Description
Technical field
Technical field is captured and launched the present invention relates to plunger, and in particular to a kind of plunger capture automatically delivery device and its
Application method.
Background technique
It can will be unable to after gas well energy production to less than critical liquid carrying flow rate with liquid output in well production
Effect carries out liquid, and as production continues, liquid will be built up in pit shaft and form hydrops, and hydrops, which exists, makes gas well can not be just
Often production, can make gas well stop production when serious.Therefore, it just needs to carry out in time drainage gas recovery when hydrops occurs in gas well, protects
Demonstrate,prove gas well steady production.
Technique of plunger gas lift is a kind of cost-effective water pumping gas production method, and plunger is launched in Wellbore of Gas Wells, utilizes gas
Well produces tolerance and pushes plunger periodic duty in oil pipe, and plunger forms mechanical packing interface, Neng Gouyou between lifting gas-liquid
Effect prevents to alter on gas to be fallen after rise with liquid, is reduced liquid " slippage " effect, is increased gas well drain efficiency.
It in technique of plunger gas lift application, needs periodically to be taken out detection and replacement to plunger, uses manual plunger at present
Catcher captures the plunger of operation, needs when capture that plunger lift well progress closing well is first reached plunger and reaches well head item
Part, operator reach gas well scene and are opened plunger catcher by being manually operated, and the back-plunger that drives a well reaches well head and is captured
Firmly.When launching plunger, plunger is installed on catcher by operator manually, hangs plunger using catcher, and drive a well process
After the completion, then catcher is closed by manual operation and discharges plunger, plunger is fallen under the effect of gravity.During manual operation,
Because manual catcher spring force is not easy to control, it may appear that capture and launch failure, influence technique applicable cases.
In plunger operational process, manual plunger catcher is in close state, and plunger is not captured after reaching well head, In
Plunger is parked in top under gas well fluid matasomatism, and rheologyization of being bullied influences, and plunger will appear concussion, when throughput is not enough to withstand column
When plug, plunger will be fallen at christmas tree valve or four-way position, will be fallen in oil pipe when serious, and under gas effect
Constantly concussion or up and down motion.
Using manual plunger catcher, manual operation heavy workload is needed, catcher launches poor reliability, increases operation
Difficulty;In addition, airflow channel can be reduced when plunger is fallen in christmas tree or oil pipe, throttle effect, winter temperature are formed when serious
It will appear hydrate frozen block when spending low;When for application packing element structure plunger, reforming phenomena, which will generate packing element performance to destroy, to be made
With shortening packing element sealed plunger application time.
When using plunger lift for big tubing string production gas well, since plunger weight is big, delivery device is captured using manual
When, it can not manually operate, while producing tolerance and be unable to continuous and effective and withstanding on plunger at the top of plunger lubricator, plunger is fallen will be tight
Blocking air-flow produces channel again, it is therefore desirable to consider that the convenient plunger of application operating captures delivery device automatically, realize that plunger arrives
Stablize after reaching and capture and launch automatically, guarantees ease-to-operate and gas well operational reliability.
Therefore, for big tubing string producing well technique of plunger gas lift application, plunger can be captured and launch automatically by having developed
Device also meets application for conventional plunger gas-lift well.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, provides a kind of plunger and capture delivery device and its user automatically
Method.The present invention can be realized plunger and capture and launch automatically, have the characteristics that control stablizes, is easy to operate.

Film valve rod (15) moves up simultaneously, and plunger lift gas well gas circulation road (8) is opened, and plunger (5) is lifted liquid and risen, when arrival plunger
After at the top of gaslift lubricator (4), liquid is contacted by discharge, plunger (5) in plunger lift gas well gas circulation road (8) with impact block (7)
Counter motion afterwards, the other end of capture block (14) will be sprung into the capture groove on plunger (5) side wall, be realized to plunger (5)
It captures, plunger (5) is in trap state at this time;
Step 2: plunger downlink is launched
On the basis of step 1 plunger (5) is in trap state, starting plunger lift controller (1) issues closing well order, micro-
After solenoid valve (2) receives order, a port of source gas line (9) connection is closed, and open company, pipeline (11) institute of losing heart
Logical third port, the gas in first switch well membrane valve (6) and second switch well membrane valve (17) be discharged it is discouraged,
One switch well film valve rod (16) and second switch well film valve rod (15) move down, at this time plunger lift gas well gas circulation road
(8) it closes, second switch well film valve rod (15) reinforces capture block (14), makes to capture after overcoming the elastic force for capturing spring (13)
Block (14) rotates clockwise withdrawal, and plunger (5) is released, and plunger (5) moves down under self gravitation effect, at this time plunger
(5) it launches successfully automatically.
Step 3:
The course of work of step 1 and step 2 is repeated, plunger (5) gaslift carries out periodically lifting liquid operation.
10. a kind of plunger according to claim 8 captures the application method of delivery device automatically, it is characterized in that: described
Plunger lift controller (1) is a kind of control controlled on telecottage's software with remote control function and realization
Device.
