Description
Technical Field
The utility model relates to an oil development equips technical field, concretely relates to plunger is from positioning system.
Background
With continuous development of gas fields, the proportion of low-yield and low-efficiency wells is increased year by year, and how to exert the productivity of the low-yield and low-efficiency wells and keep the stable production of gas wells becomes a technical problem to be solved urgently. From the evaluation result in the aspect of yield increase effect, the plunger gas lift water drainage gas production technology is suitable for gas wells with small gas quantity (more than one thousand of daily gas production quantity) and high liquid-gas ratio (less than five/ten thousand of daily gas production quantity), and the slippage loss of a shaft is small. Therefore, the plunger gas lift water drainage gas recovery technology is an effective measure for improving the recovery ratio of the low-yield low-efficiency well.
The existing plunger piston for plunger piston air lift drainage is characterized in that the lower part of the plunger piston is arranged at a proper position through a rope, the process is complex and the efficiency is low.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a plunger is from positioning system has solved the complicated and lower technical problem of efficiency of pipeline process is put into to current oil development in-process plunger. The utility model provides a plurality of technical effects that preferred technical scheme among a great deal of technical scheme can produce see the explanation below in detail.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a plunger self-positioning system comprises a pipeline arranged underground, a plunger, a detection instrument arranged on the ground of a wellhead and a nitrogen injection device; wherein:
the plunger is connected with spacing buffering nipple joint through connecting device, be equipped with the screens hole that is used for giving spacing buffering nipple joint location in the pipeline, the coating of plunger side has the soluble material coating, connecting device also adopts soluble material to make.
Preferably, the screens hole in the pipeline sets up below the liquid level.
Preferably, the soluble material is magnesium aluminum alloy.
Preferably, the thickness of the soluble material coating is the difference between the plunger tube and the plunger radius.
Preferably, the monitoring instrument is an ultrasonic range finder.
Based on the technical scheme, the following technical effects can be generated:
the embodiment of the utility model provides a pair of plunger is from positioning system can be used to plunger gas lift drainage method and transfers the plunger. The utility model relates to a self-align system of plunger is through set up soluble coating and use the connecting device that soluble material made to connect spacing buffering nipple joint between plunger side and pipeline space, meets water with connecting device when soluble coating and dissolves the back, and plunger and spacing buffer separate, and the completion is transferred to the plunger. The technical problems that the process of putting the plunger into the pipeline is complex and the efficiency is low in the existing oil exploitation process are solved. The utility model relates to a plunger arrives pipeline card position in plunger self-positioning system can automatic card and break away from with spacing buffer, avoids using the rope to put into, simplifies and puts into the step, has improved and has put into efficiency.
