Abstract
The utility model relates to a casing gas recovery device, which comprises an oil pipeline, a liquid level regulator, an air inlet pipeline, an oil-gas separator, a centrifugal compressor and a gas pipeline, wherein the oil pipeline is connected with a control valve of the liquid level regulator, an inlet end is connected with a casing, and an outlet end is connected with an oil pipe output interface; the air inlet pipeline, the oil-gas separator, the centrifugal compressor and the gas pipeline are sequentially connected; the utility model realizes the first discharge of the crude oil in the sleeve through the arrangement of the liquid level regulator; the crude oil mixed into the air inlet pipeline can be separated through the arrangement of the oil-gas separator; the oil is prevented from being diffused to the gas transmission pipeline, and production accidents caused by filling of the sleeve are avoided.
Description
Technical Field
The utility model relates to an oil field oil recovery engineering field especially relates to a sleeve pipe gas recovery unit.
Background
The production of sleeve pipe gas can produce the influence to the production efficiency of crude oil, if directly discharge into the atmosphere in the polluted environment, cause the wasting of resources, it is very necessary to provide a sleeve pipe gas recovery unit to retrieve sleeve pipe gas, and the problem of miscella is not considered to some sleeve pipe gas recovery units.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a sleeve pipe gas recovery unit to solve the problem that proposes among the above-mentioned background art. In order to achieve the above purpose, the utility model provides a following technical scheme: a sleeve gas recovery device comprises an oil pipeline, a liquid level regulator, an air inlet pipeline, an oil-gas separator, a centrifugal compressor and a gas pipeline;
the oil pipeline is connected with a control valve of the liquid level regulator, the inlet end of the oil pipeline is connected with the sleeve, and the outlet end of the oil pipeline is connected with the oil pipe output interface;
the air inlet pipeline, the oil-gas separator, the centrifugal compressor and the gas pipeline are sequentially connected;
the centrifugal compressor is detachably arranged on the gas pipeline;
the oil-gas separator is detachably arranged on the gas inlet pipeline;
when crude oil enters the sleeve and the liquid level reaches the set height of the liquid level regulator, the liquid level regulator controls a valve on an oil pipeline to be opened, and the crude oil in the sleeve is pumped out; if the oil inlet speed is too high, part of crude oil enters an air inlet pipeline, the oil gas enters an oil-gas separator through the air inlet pipeline for oil-gas separation, and separated sleeve gas is output through a gas transmission pipeline;
the embodiment of the utility model provides a beneficial effect that technical scheme brought is:
the embodiment of the utility model provides a sleeve pipe gas recovery unit realizes the first recovery of the interior crude oil of sleeve pipe through setting up liquid level regulator. And the oil-gas separator is arranged, so that the crude oil can be recovered for the second time. Through the cooperation of above device, can realize safely, high-efficiently retrieving the sleeve pipe gas in succession to can prevent that crude oil from sneaking into the gas transmission pipeline, can guarantee the normal production of oil well.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. an oil pipeline; 2. a liquid level regulator; 3. an air intake line; 4. an oil-gas separator; 5. a centrifugal compressor; 6. a gas line.
Detailed Description
The following description will be given by combining the drawings in the drawings of the embodiments of the present invention to the working principle of the casing gas recovery device provided by the present invention:
the embodiment of the utility model provides a sleeve pipe gas recovery unit, as shown in figure 1, the device includes: the device comprises an oil conveying pipeline 1, a liquid level regulator 2, an air inlet pipeline 3, an oil-gas separator 4, a centrifugal compressor 5 and an air conveying pipeline 6.
The oil outlet end of the oil pipeline 1 is connected with the crude oil output interface, and the oil inlet end is communicated with the sleeve.
The liquid level indicator of the liquid level regulator 2 is arranged on the sleeve, and the two-way valve is arranged on the oil pipeline 1.
Oil liquid enters the sleeve, when the level of the crude oil liquid reaches a certain level, the two-way valve of the liquid level regulator 2 is opened to pump the oil liquid in the sleeve out, if the oil inlet speed is higher than the oil pumping speed, part of the crude oil enters the air inlet pipeline, is separated in the oil-gas separator, is pressurized by the centrifugal compressor 5 and then is output through the air delivery pipeline 6.
