Description

Technical Field

[0001] This utility model belongs to the field of oil and gas recovery monitoring technology, specifically relating to a primary oil and gas recovery monitoring mechanism. Background Technology

[0002] In a single oil and gas recovery operation at a gas station, the entire unloading circuit is a large-channel, large-volume interconnected system. From the tanker truck → vapor hose → underground storage tank → venting pipeline, oil and gas almost instantly fill the entire space, forming a large-volume, low-concentration-gradient gas cloud. However, current sensors or sampling ports can only obtain instantaneous data at a single point within this gas cloud. In practical applications, due to the lack of a controllable, closed, and homogeneous small area of ​​oil and gas, the local, instantaneous "point concentration" cannot represent the average or peak concentration of the entire recovery process, leading to distorted calculations of recovery efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a primary oil and gas recovery monitoring mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a primary oil and gas recovery monitoring mechanism, comprising an oil and gas pipeline, an installation cylinder at the top of the oil and gas pipeline, a sealing cover rotatably mounted on the right side of the installation cylinder, an inflation valve inside the installation cylinder via an installation plug, a first pipe connected to the bottom of the inflation valve, a conversion component at the bottom of the first pipe, a mounting seat rotatably mounted on the conversion component, a monitor at the top of the mounting seat, a second pipe penetrating the left side of the mounting seat, an airbag connected to the left side of the second pipe via a first telescopic pipe, and a second telescopic pipe connected to the left side of the airbag.

[0005] Preferably, the conversion element is a hollow design.

[0006] Preferably, a third telescopic tube is connected between the left side of the conversion component and the second tube.

[0007] Preferably, a vent valve is provided on the left side of the second telescopic tube.

[0008] Preferably, an air pump is connected to the rear side of the inflation valve, and the bottom of the air pump is provided with multiple mounting holes.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] The airbag in this invention can quickly create a small local space inside the oil and gas pipeline after inflation, isolating the "large volume, low concentration gradient" gas mass into a repeatable and quantifiable test environment, making the recovery efficiency calculation closer to the true value.

[0011] This utility model, by setting an installation cylinder and a sealing cap, allows the entire mechanism to be "inserted and pulled" only above the existing oil unloading circuit, without damaging the integrity of the pipeline. After the airbag is deflated, it becomes sheet-like and can be directly pulled out from the installation cylinder without affecting normal oil unloading operations.

[0012] In this invention, by rotating the mounting base, three-section telescopic tube, and expandable airbag during the installation of the monitoring structure, it can adapt to different pipe diameters and different oil and gas media, resulting in a high number of inflation-deflation cycles and low maintenance costs.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] like Figures 1 to 4The illustrated primary oil and gas recovery monitoring mechanism includes an oil and gas pipeline, with an installation cylinder 2 at the top of the pipeline. A sealing cover 3 is rotatably mounted on the right side of the installation cylinder 2. The mechanism is characterized by an inflation valve 5 located inside the installation cylinder 2 via an installation plug 4. A first pipe 6 is connected to the bottom of the inflation valve 5, and a conversion element 7 is located at the bottom of the first pipe 6. A mounting seat 8 is rotatably mounted on the conversion element 7, and a monitor 9 is mounted on the top of the mounting seat 8. A second pipe 10 extends through the left side of the mounting seat 8, and an airbag 12 is connected to the left side of the second pipe 10 via a first telescopic pipe 11. A second telescopic pipe 13 is connected to the left side of the airbag 12. The conversion element 7 is hollow. A third telescopic pipe 14 connects the left side of the conversion element 7 to the second pipe 10. A vent valve 15 is located on the left side of the second telescopic pipe 13. An air pump 16 is connected to the rear side of the inflation valve 5, and the bottom of the air pump 16 has multiple mounting holes 17.

[0021] In this invention, the inflatable airbag 12 can quickly create a small local space inside the oil and gas pipeline after inflation, isolating the large-volume, low-concentration-gradient gas mass into a repeatable and quantifiable test environment, making the recovery efficiency calculation closer to the true value. By setting up the installation cylinder 2 and the sealing cap 3, the entire mechanism only requires "insertion and removal" above the existing oil unloading circuit, without damaging the pipeline integrity. After deflation, the airbag 12 is sheet-like and can be directly extracted from the installation cylinder 2 without affecting normal oil unloading operations. In this invention, by rotating the mounting base 8, the three-section telescopic tube, and the expandable airbag 12 during the installation of the monitoring structure, it adapts to different pipe diameters and different oil and gas media, resulting in a high number of inflation-deflation cycles and low maintenance costs.

[0022] Example 2

[0023] like Figures 1 to 4 The illustrated primary oil and gas recovery monitoring mechanism includes an oil and gas pipeline for primary oil and gas recovery. An installation cylinder 2 is provided at the top of the oil and gas pipeline, and a sealing cover 3 is rotatably provided on the right side of the installation cylinder 2. The sealing cover 3 is used to seal the oil and gas pipeline during normal operation. When it is necessary to monitor the primary oil and gas, the sealing cover 3 can be opened, and the monitoring structure can be placed into the oil and gas pipeline through the installation cylinder 2 to realize oil and gas monitoring.

[0024] In this embodiment, the monitoring structure specifically includes: an installation plug 4 with the same inner diameter as the installation cylinder 2, the installation plug 4 being located at the lower part of the inflation valve 5, so that the inflation valve 5 can be installed on the oil and gas pipeline through the installation plug 4, the bottom of the inflation valve 5 being connected to a first pipe 6, the bottom of the first pipe 6 being provided with a conversion component 7, the conversion component 7 being specifically a conversion from a vertical pipe to a horizontal pipe, the conversion component 7 being a hollow design, that is, the conversion component 7 being able to communicate upward with the first pipe 6; an installation seat 8 being rotatably provided on the conversion component 7, the left side of the installation seat 8 being provided with a second pipe 10, when a third telescopic pipe 14 is connected between the second pipe 10 and the left side of the conversion component 7, it means that the second pipe 10 can rotate below the first pipe 6, and can also communicate with the first pipe 6 and the inflation valve 5; it is understood that the user can first rotate the installation seat 8 to keep the second pipe 10 in a vertical state, for inserting the installation cylinder 2 into the oil and gas pipeline.

[0025] The second tube 10 is connected to an airbag 12 via a first telescopic tube 11 on its left side. The airbag 12 is connected to a second telescopic tube 13 on its left side. Furthermore, the user can first rotate the mounting base 8 to keep the second tube 10 vertical, and then reduce the size of the first telescopic tube 11, airbag 12, and second telescopic tube 13 connected to the second tube 10 to their minimum dimensions for insertion into the oil and gas pipeline. In practical applications, the user opens the sealing cap 3, inserts the monitoring structure into the oil and gas pipeline through the mounting cylinder 2, and fixes the mounting plug 4 inside the mounting cylinder 2. The insertion sequence is: second telescopic tube 13, airbag 12, first telescopic tube 11, and second tube 10. After the second tube 10 contacts the inner wall of the pipeline, it is forced to rotate the mounting base 8. At this time, the third telescopic tube 14 bends, becoming perpendicular to the first tube 6. Therefore, by simply installing the monitor 9 on the top of the mounting base 8, the oil and gas inside the oil and gas pipeline can be monitored.

[0026] Furthermore, an air pump 16 is provided, which is connected to the inflation valve 5. The air pump 16 can be fixed by the four mounting holes 17 at the bottom. After fixing, the air pump 16 is started and works with the inflation valve 5 to inflate the airbag 12 located in the pipeline, intercepting oil and gas to form a test area for monitoring by the monitor 9. In addition, an air release valve 15 is provided on the left side of the second telescopic tube 13. After monitoring is completed, the air in the airbag 12 is released, causing the airbag 12 to shrink to a sheet shape, which is conducive to the removal of the monitor 9. After removal, the sealing cover 3 is rotated back to its original position, restoring the normal operation of the oil and gas pipeline.
