Description
Technical field:
The present invention relates to a kind of with the desirable instrument that is used for deep drilling and workover treatment in oil drilling and the workover treatment.
Background technology:
All in 120 °, used helicoid hydraulic motor universal joint adopts hermetic for present used oil drilling in oil field and workover treatment plain edition helicoid hydraulic motor, heatproof.Stationary part adopts the liner packing element, and rotor portion adopts chromium coating.At the running part of helicoid hydraulic motor, adopt on 8 groups of string bearings, the TC bearing is shorter, and the helicoid hydraulic motor that makes like this can better bear the vibrations that the buffering downhole drill bit passes to helicoid hydraulic motor in deep-well work.
Summary of the invention:
A kind of oil drilling and workover treatment instrument of being applied to, universal joint partly adopts the intermediate distributary falling temperature method, to reduce by the mud temperature of helicoid hydraulic motor, in the screw drilling tool motor part, stationary part adopts high temperature resistant alkaline-resisting acid-resisting rubber to vulcanize, and rotor portion adopts the tungsten alloy electroplating technology to have splendid covering power and an ancient unit of weight plating ability.Running part at helicoid hydraulic motor, adopt 10 groups of string bearings, the TC bearing has extended 50 millimeters, sealing device is adopted at the power transmission shaft position, be installed in spacer or power transmission shaft outer and transmission shaft shell or time pipe nipple, lay respectively at the lower end of journal bearing upper end and lower radial bearing, the helicoid hydraulic motor that makes like this can better bear the vibrations that the buffering downhole drill bit passes to helicoid hydraulic motor in deep-well work.
High temperature deep well screw drilling tool mainly is made up of four parts:
1. bypass valve parts 2. motor parts
3. universal joint parts 4. power transmission shaft parts
Helicoid hydraulic motor implement to use: by-pass valve of screwdrill has bypass and closes two positions, is in bypass position in the round trip process, makes in the drill string mud circulation walk around the motor of not working and enters annular space, and mud does not overflow on raised platform around a well when making a trip like this.When mud flow rate and pressure reached typical set value, spool moved down, and closes the bypass valve opening, this moment slurry flows through motor, can be transformed into mechanical energy to pressure.When the slurry flows value during too small or termination of pumping, the insufficient pressure that is produced when overcoming spring force and stiction, spring handle spool jack-up, the bypass valve opening is in the enable possition again.The motor of helicoid hydraulic motor is a positive displacement, and the factor of decision drilling tool performance is that the input flow rate of motor and the pressure that acts on two ends fall, rather than the type of drilling fluid.The physical and chemical performance of drilling fluid does not generally influence the drilling tool performance except that diminishing individually the drill tool life, should note considering the needs of drilling technology.But the contained various grits of drilling fluid must be limited, and in the application life of reducing drilling tool because it can quicken the wearing and tearing of bearing, motor, suggestion solid phase sand content is no more than 1% (fact proved: if sand content reaches 5%, drill tool life can reduce by 50%).Note simultaneously not being mixed with all gases in the drilling fluid, be easy to generate " cavitation effect " because be mixed with under the variation of drilling fluid pressure in drilling tool of gas, the damage, the especially stator rubber that quicken drilling tool are easier to be bad by cavitation erosion, must give enough attention.The operating characteristic of this helicoid hydraulic motor is, the height of its rotating speed is directly proportional with the flow of transferring power medium, pressure general who has surrendered by helicoid hydraulic motor is directly proportional with the moment of torsion that is produced, that is to say, be directly proportional with the pressure of the drill, the pressure of the drill increases, and moment of torsion and circulating pressure all will increase, so just can be according to circulating pressure accurately at control the pressure of the drill.After drilling tool uses, should dismantle immediately, check universal drive shaft, check power transmission shaft, surpass maintenance standard, should in time change relevant consumable accessory as wear extent, otherwise can because of overusing of universal drive shaft causes drilling tool can't operate as normal.
This helicoid hydraulic motor and conventional screw drilling tool difference are:
Driving-shaft assembly: at the running part of helicoid hydraulic motor, with original string bearing on original 8 groups, be improved to present 10 groups, original TC bearing has been extended 50 millimeters, the helicoid hydraulic motor that makes like this can better bear the vibrations that the buffering downhole drill bit passes to helicoid hydraulic motor in deep-well work.
Motor: in the screw drilling tool motor part, the high temperature resistant alkaline-resisting acid-resisting rubber that the liner packing element of original stationary part is modified into the import prescription vulcanizes on the stator of helicoid hydraulic motor, and rotor portion adopts the tungsten alloy electroplating technology to have splendid covering power and an ancient unit of weight plating ability.
Universal joint: we rotate universal joint assembly the off-centre of rotor to have become concentric rotation, design is unique in this respect, it can avoid the universal joint of other design to produce fracture and stuck phenomenon, the design universal joint adopts the intermediate distributary falling temperature method like this, better will reduce by the mud temperature of helicoid hydraulic motor.
