Abstract
A kind of integrated oil field gas injection distribution controller is used for viscous crude field steam and annotates distribution of vapour amount and control.Annotate the vapour well at each mouthful an electrically operated valve and corresponding valve core position sensor are all arranged.It is characterized in that: there is standard industrial control the centre that is divided into a group with several mouthfuls of notes vapour wells, each motor operated valve and family of power and influence's core position sensor all have suitable module to insert in the control interface, and the control interface of each group is connected in series in the central control computer serial ports that can have by cable.Use a computer and annotate distribution of steam flow amount and control notes vapour automatically, higher precision is not only arranged, and do not need artificial manual operations.
Description
A kind of integrated oil field gas injection distribution controller, it is used for the oil-field thick-oil exploitation, and steam is annotated the notes vapour amount of vapour well and distributed and control, be a kind of control and measurement mechanism of electromechanical integration.
For full-bodied oil exploitation, need to adopt at some specific oil wells (or the special-purpose vapour well of annotating) and inject a certain amount of high temperature and high pressure steam, to increase the flowability of thickness oil, be convenient to exploitation.Because the geological characteristics difference of every mouthful of well requires (mainly being to annotate the steam flow amount) also different to steam injection parameter.Need more energy owing to produce steam, now forms of using large-sized boiler to concentrate steam supply to improve the thermal efficiency of boiler more.By the steam distribution pipeline steam is transported to each mouthful notes vapour well head, the steam that needs flow is injected well by distributing valve and flow measurement device.Because the steam production of steam supply boiler has certain fluctuating error, adding boiler duty can not regulate fully as required in real time, all arranged a lag time, thereby every mouthful of notes steam flow amount of annotating the vapour well can not be determined fully as required, also must distribute, therefore need often to adjust every mouthful of notes steam flow amount of annotating the vapour well according to the size of total evaporation capacity for engine.The distribution of oil field gas injection flow is now manually carried out with the many employings of control, by artificial dispensed volume and by transmission instructions such as phones, respectively to annotate vapour by operating personnel's manual adjustment and distribute valve, this has not only increased more operation element amount, and control accuracy is lower, and the control response time is long.
The objective of the invention is to invent a kind of oil field gas injection distribution controller that can distribute and control to adjust notes vapour well notes steam flow amount automatically of electromechanical integration.It can have high control precision according to the automatic accommodometer point counting of total air demand flow amount, does not need the aperture of the manual operated allocated steam valve of people.
The present invention as shown in Figure 1.In the controlled notes vapour of each mouthful well head part an electrically operated valve 1 and corresponding valve core position sensor 2 are arranged all, it is characterized in that: several mouthfuls of controlled notes vapour wells are divided into one group, a standard industrial control 3 is arranged in the centre of each group, each electrically operated valve 1 respectively has the adaptation module 5 of its switching of control and the measurement adaptation module 6 that links to each other with corresponding valve core position sensor 2, belong to the same group of adaptation module 5 and 6 of annotating the vapour well and insert in the same standard industrial control 3, the standard industrial control 3 of each group uses the series connection of standard serial communication interface to be connected on the serial communication interface that can be the common central control computer of other observing and controlling control equipment 4.
Among the present invention, form an executive system that the notes steam flow amount of each notes vapour well is controlled by each electrically operated valve 1 and valve core position sensor 2.The aperture of electrically operated valve 1 is measured by valve core position sensor 2.During this device busy, central control computer 4 obtains total evaporation capacity for engine signal, allocation strategy by pre-depositing computer and each is annotated vapour well parameter calculate calculates and respectively annotates the opening value that the vapour well is annotated the needed electrically operated valve 1 of steam flow amount, and compares with present value.The present value of each electrically operated valve aperture is used the mode of scanning by central control computer 4, send gating successively and respectively annotate the address gating signal of the measurement adaptation module 6 that the pairing valve core position sensor 2 of vapour well connected, gating inserts this measurement adaptation module 6 in the respective standard industrial control interface 3, receives the valve opening value that this module is passed back then.For electrically operated valve 1 through determining relatively afterwards to adjust, central control computer 4 is sent the address gating signal of this valve control adapter module 5 earlier, by this adaptation module of corresponding standard industrial control interface 3 gatings, central control computer 4 is sent corresponding electrically operated valve opening value then, after the adaptation module 5D/A conversion by this gating electrically operated valve 1 is controlled.
In the present invention, owing to adopted central control computer and standard industrial control to add the electromechanical integration mode of execution and measuring cell, the distribution and the control that use a computer and annotate the steam flow amount can have best allocation strategy.Simultaneously, the method by numerical control directly changes the aperture of each valve and measures existing opening value, and not only control rate responds, the time short, and higher precision is arranged, and does not need that personnel are manual to operate each valve, has alleviated labour intensity.
The notes vapour well number that the present invention is suitable for controlling can be tens mouthfuls, tens mouthfuls, up to a hundred mouthful so that more.Annotating the packet count of vapour well determines according to geographical position of annotating the vapour well and the slot count in the standard industrial control.Because annotating the vapour well will insert two adaptation module flatly, thereby for the standard industrial control that 16 slots are arranged, every group of maximum well number is 8 mouthfuls.Every group of well number can be less than this number.The slot of standard industrial control can stick with, and is measurement and the control module that increases other, can also insert other adaptation module, as increasing the temperature survey adaptation module.Standard industrial control 3 should be not excessive apart from the distance of each well, arrives by the wire length between control elements or the sensor to shorten adaptation module.A plurality of standard industrial control 3 link to each other by a standard serial communication cable, and each standard industrial control 3 is assigned different base address.Make central control computer 4 carry out observing and controlling by a standard serial communication interface.
Electrically operated valve 1 of the present invention can use the various valves of controlled opening amount.Can be Control of Voltage, also can be Current Control.Valve core displacement sensor 2 can use magnetic induction measurement form, photoelectric measurement form or capacitance measurement form.Electrically operated valve 1 and valve core displacement sensor 2 have become standard merchandise, as product G ENERAL SERVICE-MODEL 120, the MODEL 220 of U.S. TARGT ROCK company.Adaptation module 5 and measurement adaptation module 6 can be used the AD3 and the DA3 product of U.S. OPTO 22 companies.
In the present invention, standard industrial control 3 can be selected the I/O K32 of U.S. ME company (MECHATRONIC EQUIPMENT INC.) for use, or the PB16AH of U.S. OPTO 22 companies.Central control computer 4 can be selected the LC4 controller of U.S. OPTO 22 companies for use, also can select the PCS-1 industrial process control work station of U.S. ME company for use, can also select common PC computer for use.
