Abstract
The problem of a kind of long-range natural gas belching well constant speed drives a well device, is a kind of production gas technology of Gas Industry, solves the long-range constant speed of natural gas belching well and drive a well, long-range closing well.Technical solution will put 1 to switch remote on/off solenoid valve using 4Gwifi, and control membrane valve is turned on and off, to drive a well or closing well.Technical solution will put 2 as using oil pressure cntrol feedback reduced pressure valve, when oil pressure reduces, Pneumatic diaphragm valve pneumatic system pressure increases, and air bladder valve opening increases, and ensures that constant speed drives a well.
Description
Technical field
It drives a well device the present invention relates to drive a well between natural gas automatic drive a well device, especially constant speed.
Background technology
Su Lige, pacify the border region, total developed in Yulin, sub- continent and five big main force gas field of Shenmu County verifies oil in place 1.95 trillion
Side has developed and has verified 300,000,000,000 side of oil in place or more substantially;Classification of Gas Pools boundary according to national standards belongs to hypotonic-cause
Close reserves, Soviet Union's Sulige gas field investigates out low yield altogether in by the end of June, 2016 for cut-off(The daily output is less than 5000 sides)5184 mouthfuls of gas well, accounts for
The 57.5% of the total well number in gas field, and stripper well well number is climbed to a higher point year by year.Fig. 1 is stripper well well number cumulative year after year block diagram.Gas well is natural
Successively decreasing causes gas well middle and later periods pressure and yield to reduce, and gas well fluid-carrying capability is poor, and gas well is unable to the problem that continuous production is main.
Drive a well between low yield more problems during driving a well at present:
(1)Manually drive a well since the quantity of well is more, it is of high cost;
(2)Plunger and intelligence, which drive a well just to drive a well, to be flowed through greatly in pressure wink, causes block valve take-off, gas gathering station drain are too late to cause to compress
Machine is shut down.And due to can the quantity-produced period, gas well fluid-carrying capability is poor, causes near wellbore zone and wellbore effusion, reduce
The recovery ratio of reservoir reduces;To solve the above problems, be badly in need of wanting it is a kind of can long-range switchable and controllable flow velocity device, this hair
Bright patent meets the actual requirement of production.
Invention content
Technical problem to be solved:Automatically during driving a well, height is flowed through wink, some belching wells are more than 10x104m3/ d, production
Liquid measure is excessive, on the one hand may cause compressor shutdown, and production liquid excessively makes gas field more than separator designed capacity in the short time
Production fluid enters gathering line and causes liquid stifled or frozen block, influences production system stabilization.On the other hand due to reservoir short time energy
Release, pit shaft and near wellbore zone reservoir hydrops make the reduction of reservoir recovery ratio, so driving a well ensure well head not frozen block situation
It opens slowly down.Solve technical solution and advantage used by its technical problem:Because of gas well capacity and oil pressure when driving a well
It is directly proportional, so selecting oil pressure to be fed back as control, by increasing feedback reduced pressure valve, by hand reducing pressure valve and oil pressure feedback control
System pressure.When the oil pressure is low, system pressure rises, and pressure control aperture air bladder valve opening becomes larger.When oil pressure is high, it is
Pressure of uniting declines, and pressure control aperture air bladder valve opening becomes smaller.To ensure that gas well constant speed produces, reduction drives a well to collecting defeated
The impact of system improves reservoir recovery ratio, reduces the cost that manually drives a well.The long-range natural gas belching well constant speed of Fig. 2 drives a well device skill
Art solution principle figure.
Claims (4)
- The device 1. a kind of natural gas belching well constant speed drives a well, which is characterized in that remote control module, Pneumatic control module are described Remote control module is used for remote switch well;The Pneumatic control module for realizing switch well and ensures the well when driving a well Flow substantially constant.
