Abstract

An electrical transmission assembly for drill pipe segments for a drill string for oil wells and gas wells. A resilient pipe segment lining having an embedded lining conductive element extending from a first lining inductive element to a second lining inductive element is affixed to the interior surface of the pipe segment. A support sleeve dimensioned for slidable mating with the interior surface of the resilient pipe segment lining has an embedded sleeve conductive element extending from a first sleeve inductive element to a second sleeve inductive element. The position of the first and second sleeve inductive elements respectively provide for them to be positioned radially and longitudinally proximal to the first and second lining inductive elements respectively as the pipe segments are threaded together.

Description

BACKGROUND

During modern drilling operations, data is acquired from drilling rig sensors for a range of purposes such as (1) monitoring and managing the smooth operation of drilling; (2) making a detailed log of the geologic formations penetrated by a borehole; (3) generating operations statistics and performance data. Measurement While Drilling (MWD), and Logging While Drilling (LWD) are terms commonly used in the industry for collection of data from drilling rig sensors. The term MWD refers to directional drilling measurements, e.g., for decision support for the smooth operation of the drilling, while LWD refers to measurements concerning the geological formation made while drilling.
MWD data may include measurements taken of the wellbore inclination from vertical and inclination from magnetic north. Directional survey measurements are typically taken by three orthogonally mounted accelerometers to measure inclination, and three orthogonally mounted magnetometers which measure direction (azimuth). Gyroscopic tools may also be used to measure Azimuth. MWD tools are generally capable of taking directional surveys in real time. With this data, a three-dimensional plot of the path of the well can be produced. A MWD Operator monitors the trajectory of the hole as it is drilled, using data that is updated and processed every few seconds or faster. This information is then used to drill in a pre-planned direction into the formation which contains the oil, gas, water or condensate. Measurements may also be taken of natural gamma ray emissions from the rock for use in determining what type of rock formation is being drilled, and, thus, by comparison with existing seismic data, the real-time location of the wellbore in relation to known formations. Directional drillers rely on receiving accurate, quality tested, real time data from the MWD Operator to allow them to keep the well drilling on the planned trajectory. For the directional driller to steer the well towards a target zone, he must know where the well is going, and what the effects of his steering efforts are.
Downhole electrical and mechanical power may be provided by downhole turbine systems, which use the energy of the drill fluid flow, battery units, or a combination of both.
MWD tools can be used to provide a variety of information about the conditions at the drill bit. The information may include rotational speed of the drill string, smoothness of that rotation, type and severity of any vibration downhole, downhole temperature, torque and weight on bit, and mud flow rate.
This information can be used by the operator to drill the well more efficiently, and to ensure that the MWD tool and any other downhole tools, such as a mud motor, rotary steerable systems, and LWD tools, are operated within their technical specifications to prevent tool failure. This information is also valuable to Geologists responsible for the well information about the formation which is being drilled.
There are a number of methods used to transmit data from the surface and the drill bit or other downhole tools, and to transmit data between the drill bit and other downhole tools and sensors to the surface. A common method of data transmission used by MWD tools is the use of drill fluid pressure signals. Downhole, a valve is operated to restrict the flow of the drilling mud (slurry) according to the digital information to be transmitted. This creates pressure fluctuations representing the information. The pressure fluctuations propagate within the drilling fluid towards the surface where they are received from pressure sensors. On the surface, the received pressure signals are processed by computers to extract the information.
Other measurements often require separate LWD tools, which communicate with the MWD tools downhole through internal wires. These tools incorporate an electrical insulator in the drill string. To transmit data, the tool generates a modulated voltage (electronic pulse telemetry) between the top part (the main drill string, above the insulator), and the bottom part (the drill bit, and other tools located below the insulator of the MWD tool). On surface, a wire is attached to the wellhead, which makes contact with the drill pipe at the surface. A second wire is attached to a rod driven into the ground near the wellhead. The wellhead and the ground rod form the two electrodes of a dipole antenna. The voltage difference between the two electrodes is the receive signal that is decoded by a computer. The tool generates voltage differences between the drill string sections in the pattern of very low frequency (2-12 Hz) waves. The data is imposed on the waves through digital modulation. In addition, many of these tools are also capable of receiving data from the surface in the same way, while mud-pulse-based tools rely on changes in the drilling parameters, such as rotation speed of the drill string or the mud flow rate, to send information from the surface to downhole tools. Making changes to the drilling parameters in order to send information to the tools generally interrupts the drilling process, causing lost time. Compared to mud-pulse telemetry, electronic pulse telemetry is more effective in certain specialized situations, such as under balanced drilling or when using air as drilling fluid. It is capable of transmitting data up to ten times faster. However, it generally falls short when drilling exceptionally deep wells, and the signal can lose strength rapidly in certain types of formations, becoming undetectable at only a few thousand feet of depth.
For the modern drilling of directional, deep wells, there is increasing use of transmission wire assemblies incorporating insulated wire conductors for the transmission of data signals between the surface and the drill bit and other downhole tools and sensors. Electrical transmission wire assemblies of this variety may also used for the transmission of electric power downhole from the surface. Many of the oil wells and many of the gas wells being drilled today are drilled to depths of 5,000 to 15,000 feet. With the common 31 foot length for the pipe segments, often referred to as “drill rods”, of the drill string used to drill such wells, this range of well depths requires between 160 and 480 pipe segments. At the bottom of the drill string is a drill bit that may operate to drill through rock by torque applied at the surface and transmitted to the drill bit through the drill string. The pipe segments of the drill string transmit drill fluid pumped from a drill fluid pump located at the surface to the drill bit for cooling and flushing the drill bit and pushing the rock cuttings from the drill bit up the annular space between the drill string and the rock wall of the borehole, or well casing, to the surface. For directional drilling control signals that are to be transmitted by a transmission wire assembly from the surface to the drill bit, and for MWD and LWD signals that are transmitted by a transmission wire assembly from borehole sensors to the surface, the transmission wire assembly must provide for the segment by segment assembly of the drill pipe and the transmission of the control signals and the sensor signals from segment to segment for the entire length of the drill string. The simplest of such transmission wire assemblies consist merely of an insulated wire, with periodic sealed mechanical and electrical connections, freely positioned in the inner fluid chamber of the drill pipe segments of the drill string which is used for the pumping of drill fluid from the surface to the drill bit. The transmission wire may be periodically attached to the drill string. More complex transmission wire assemblies involve electrical or induction connections at each pipe segment joint between connected pipe segments.
Several oilfield equipment companies are currently marketing wired drill pipe systems. These systems use electrical wires built into every component of the drill string, which transmit electrical signals directly between the surface and the downhole tools. These systems provide data transmission rates orders of magnitude greater than anything possible with mud-pulse or electromagnetic telemetry, both from downhole tools to the surface and from the surface to downhole tools.
There are a number of transmission wire assemblies and systems disclosed in the prior art providing for the direct transmission of electrical signals between the surface and the drill bit, downhole tools, and downhole sensors. Those prior art assemblies and systems have met with varying degrees of success. Prior art assemblies and systems have varying limitations and vulnerabilities, including vulnerability to physical damage during installation or operation, difficulty and unreliability of assembly, and signal transmission unreliability.
In the present specification, including the claims, the term “electrical transmission assembly” as applied to the present invention, for use with drill pipe segments for a drill string for oil wells and gas wells, shall be defined to include an electronic transmission assembly for electronic communication signal transmission between adjacent drill pipe segments of a drill string comprised of a plurality of drill pipe segments, and shall be defined to include an electrical transmission assembly for electrical power transmission between adjacent drill pipe segments of a drill string comprised of a plurality of drill pipe segments.
An objective of the present invention is to provide an electrical transmission assembly for drill pipe segments for a drill string for oil wells and gas wells with enhanced ease of drill string assembly and reduced vulnerability during installation and operation.
A further objective of the present invention is to provide an electrical transmission assembly for drill pipe segments for a drill string for oil wells and gas wells with improved reliability for achieving desired electrical connectivity during drill string assembly and improved reliability of signal transmission during operation.
A still further objective of the present invention is to provide an electrical transmission assembly for drill pipe segments for a drill string for oil wells and gas wells with enhanced signal strength maintenance for directional, deep well drilling.
A still further objective of the present invention is to provide an electrical transmission assembly for drill pipe segments for a drill string for oil wells and gas wells with enhanced signal strength maintenance for MWD tools and LWD tools.

SUMMARY OF THE INVENTION

The electrical transmission assembly of the present invention provides for electronic communication signal transmission or for electrical power transmission between adjacent drill pipe segments of a drill string, for oil or gas well drilling, comprised of a plurality of drill pipe segments. Each drill pipe segment has a segment first end and a segment second end. The segment first end has a tapered female threaded connector with a female connector inside end and the segment second end has a tapered male threaded connector with a male connector outside end. The tapered female threaded connector typically has a mechanical coupling capability for mechanically coupling with the tapered male threaded connector of a first adjacent pipe segment, and the tapered male threaded connector has a mechanical coupling capability for mechanically coupling with the tapered female threaded connector of a second adjacent pipe segment. The tapered female threaded connector may be mechanically coupled with the tapered male threaded connector of a first adjacent pipe segment by the tapered male threaded connector of the first adjacent pipe segment being threaded together with the tapered female threaded connector. Likewise, the tapered male threaded connector may be mechanically coupled with the tapered female threaded connector of a second adjacent pipe segment by the tapered male threaded connector being threaded together with the tapered female threaded connector of the second adjacent pipe segment. Each drill pipe segment has a segment interior surface which extends from the female connector inside end to the male connector outside end.
A preferred embodiment of the electrical transmission assembly of the present invention may incorporate a resilient pipe segment lining which is affixed to the segment interior surface and which may preferably extend from the female connector inside end to the male connector outside end. The resilient pipe segment lining may preferably be bonded to the segment interior surface, but alternatively may be affixed to the segment interior surface by means that will be known to persons of skill in the art, in view of the disclosures of this specification and the drawings.
The resilient pipe segment lining may have one or more lining conductive elements which may be embedded in the resilient pipe segment lining and may preferably extend from a first lining inductive element to a second lining inductive element. Preferably the lining conductive elements and the lining inductive elements are completely encased and sealed by the resilient pipe segment lining, thereby protecting the lining conductive elements and the lining inductive elements from direct exposure to the environment of the drill string.
A preferred embodiment of the electrical transmission assembly of the present invention incorporates a support sleeve which may have a sleeve insertion portion and a sleeve extension portion. The sleeve insertion portion may be dimensioned for slidable mating with the resilient pipe segment lining at the female connector inside end. The sleeve extension portion may be dimensioned for slidable mating with the resilient pipe segment lining at the male connector outside end in the pipe joint of the pipe segment with the first adjacent pipe segment as the male connector outside end of the first adjacent pipe segment is threaded into the female connector inside end of the pipe segment.
One or more sleeve conductive elements may be embedded in the support sleeve and may preferably extend from a first sleeve inductive element positioned at a first sleeve inductive element position to a second sleeve inductive element positioned at a second sleeve inductive element position. The first sleeve inductive element position provides for the first sleeve inductive element to be positioned radially and longitudinally proximal to a first lining inductive element as the sleeve insertion portion of the support sleeve is inserted in the resilient pipe segment lining at the female connector inside end, positioning the support sleeve in the service position. With the support sleeve in the sleeve service position, the second sleeve inductive element position provides for the second sleeve inductive element to be positioned radially and longitudinally proximal to a second lining inductive element of the first adjacent pipe segment as the male connector outside end of the first adjacent pipe segment is threaded into the female connector inside end of the pipe segment. The foregoing may be repeated for each pipe joint of the drill string. This provides for the transfer of an electrical communication signal or electric power between the pipe segments of the drill string.
In addition to providing for the electrical connectivity between each of the pipe segments through the inductive interaction between the first sleeve inductive element and the first lining inductive element, and through the inductive interaction between the second sleeve inductive element and the second lining inductive element, the support sleeve may provide support and protection to the resilient pipe segment lining at and proximal to the first lining end at the female connector inside end, and at and proximal to the second lining end at the male connector outside end.
