In particular, after gas injection, it is difficult to obtain the venting test data required by the geological department in a timely manner. To address these issues, this invention designs and manufactures a mobile venting medium recovery device, overcoming the aforementioned shortcomings. Utility Model Content

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1

[0031] Reference Figure 1-6This is the first embodiment of the present invention, which provides a mobile discharge medium recovery device, including,

[0032] The main structure 100 includes a device skid 101, a support base 102 fixedly installed on the top of the device skid 101, a tank assembly 103 set on the top of the support base 102, a protective assembly 104 set on the top of the tank assembly 103, two auxiliary storage boxes 105 symmetrically arranged at the bottom of the tank assembly 103, two sets of lifting lugs 106 symmetrically arranged on both sides of the device skid 101, and a control cabinet 107 fixedly installed on the top of the device skid 101.

[0033] The transmission mechanism 200 includes a liquid inlet assembly 201 disposed at one end of the tank assembly 103, an oil delivery assembly 202 disposed at the other end of the tank assembly 103, a loading assembly 203 disposed on one side of the oil delivery assembly 202, and a monitoring assembly 204 disposed on the top of the device skid 101. The monitoring assembly 204 is used to control the overall device.

[0034] Specifically, the tank assembly 103 includes a recovery tank 103a fixedly installed on the top of the support base 102, a venting medium inlet 103b opened at the top right end of the recovery tank 103a, and an oil level observation port 103c provided on one side of the venting medium inlet 103b.

[0035] Furthermore, the tank assembly 103 also includes a flame arrestor breather valve 103d located on one side of the oil level observation port 103c, a manhole 103e located on one side of the flame arrestor breather valve 103d, and a drain port 103f located at the bottom left end of the recovery tank 103a.

[0036] It should be noted that the device bottom skid 101 provides stable support, the auxiliary parts storage box 105 is used to store components such as the flame arrester breather valve 103d that may be subject to ultra-high height restrictions during transportation, and the lifting lug 106 is used for the rapid relocation of the device.

[0037] Furthermore, the protective assembly 104 includes a split-type protective cage 104a fixedly installed on the top right end of the recycling tank 103a, a support grid platform 104b fixedly installed on the top of the recycling tank 103a, and a folding guardrail 104c set on the top of the support grid platform 104b. The folding guardrail 104c is connected to the support grid platform 104b by a hinge pin, and the split-type protective cage 104a is fixedly connected to one end of the support grid platform 104b.

[0038] It should be noted that the support grid platform 104b is welded to the top of the recycling tank 103a with angle steel, and together with the split-type protective cage 104a and the folding guardrail 104c, it plays a safety protection role. The split-type protective cage 104a can be separated into upper and lower half protective cages. A pin is set at the upper end of the lower half protective cage and a pin tube is set at the lower end of the upper half protective cage. The two can be separated or combined at will. The design of the above structure effectively reduces the height of the device.

[0039] The liquid inlet assembly 201 includes a drain pipe 201a located at the bottom right end of the recovery tank 103a, a drain gate valve 201b fixedly connected to the end of the drain pipe 201a, a three-way pipe 201c fixedly connected to the end of the drain gate valve 201b, and an electric ball valve 201d located at the top of the three-way pipe 201c.

[0040] Preferably, the liquid inlet assembly 201 also includes an inlet pipeline 201e connected to the top of the electric ball valve 201d, an electric butterfly valve 201f disposed on the inlet pipeline 201e, and a pipe-type separator 201g disposed on the top of the discharge medium inlet 103b, the pipe-type separator 201g being connected to the inlet pipeline 201e.

[0041] It should be noted that the inlet process pipeline 201e is equipped with a detachable tee pipe 201c. One end of the inlet process pipeline 201e is connected to the flange on the edge of the unit's bottom skid 101, and the other end is connected to the tee pipe 201c. When sewage needs to be discharged, the tee pipe 201c can be removed and a sewage discharge pipe can be installed for sewage discharge. The pipe-type separator 201g is designed in the shape of a pipe and has a built-in separation wire mesh. The medium passes through the pipe separator and undergoes pressure reduction, diffusion, and buffering. The separated oil droplets fall into the recovery tank 103a, and the gas is discharged from the flame arrestor breather valve 103d.

[0042] Specifically, the oil delivery assembly 202 includes an intake process manifold 202a fixedly connected to the drain port 103f, a main gate valve 202b disposed on the intake process manifold 202a, a filter cylinder 202c disposed on the intake process manifold 202a, and a discharge process manifold tee 202d connected to the filter cylinder 202c.

[0043] Furthermore, the oil transfer assembly 202 also includes an oil pump 202e fixedly installed on the top of the device skid 101, an oil pump inlet gate valve 202f installed on the side of the discharge process manifold tee 202d near the oil pump 202e, a check valve 202g installed on the output pipe of the oil pump 202e, and an inlet manifold gate valve 202h installed on the discharge process manifold tee 202d.

[0044] Furthermore, the loading assembly 203 includes an infusion line 203a located at the output end of the inlet manifold gate valve 202h, a loading pump 203b fixedly connected to the infusion line 203a, a safety valve 203c located on the infusion line 203a, a lifting component 203d located on the top of the device skid 101, a loading arm rotating component 203e located on the top of the lifting component 203d, a loading arm 203f located inside the loading arm rotating component 203e, an electric valve 203g located on the loading arm 203f, and a loading arm bracket 203h located on the top of the device skid 101. The loading arm 203f is fixedly connected to the output end of the loading pump 203b, and the top of the loading arm bracket 203h is fixedly connected to the bottom of the loading arm 203f.

[0045] It should be noted that one end of the suction process manifold 202a is connected to the outlet flange of the recovery tank 103a, and the other end is connected to the inlet flange of the loading pump 203b. The lifting component 203d is slidably connected to the electro-hydraulic lifting column and the 180° sliding rod nut, which plays the role of lifting the loading arm to overcome the requirements of overheight and overlength transportation. The rotating component 203e of the loading arm is composed of a reversible motor, gears, lifting slide rods and socket couplings. The reversible motor provides 180° reciprocating power. The lifting slide rods and socket couplings are responsible for connecting the gears. The small gear drives the large gear to reciprocate, so as to achieve the purpose of rotating the loading arm 203f.

[0046] When in use, the entire device is transported to the work site and fixed with the help of the lifting lugs 106 on both sides of the device bottom skid 101. Then, the fire arrestor breathing valve 103d and other components are taken out from the auxiliary parts storage box 105 and installed. Then, the folding guardrail 104c is unfolded and it is securely connected to the support grid platform 104b through the hinge pin. At the same time, the split guardrail 104a is assembled through the pin.

[0047] When recovering the vented medium, connect the external vented pipeline to the flange at the end of the inlet pipeline 201e, open the electric butterfly valve 201f and the electric ball valve 201d, and the vented medium enters the pipe-type separator 201g through the inlet pipeline 201e, where oil and gas are separated. The oil droplets enter the recovery tank 103a from the vented medium inlet 103b, and the separated gas is safely discharged through the flame arrestor breather valve 103d.

[0048] When the medium needs to be loaded onto the truck, the main gate valve 202b is opened. The medium in the recovery tank 103a enters the suction process manifold 202a through the drain port 103f. After passing through the filter cylinder 202c to filter impurities, it enters the discharge process manifold tee 202d. The loading pump 203b is started through the control cabinet 107. The medium enters the infusion pipeline 203a through the inlet manifold gate valve 202h. The lifting component 203d adjusts the height of the loading arm 203f. The loading arm rotating component 203e drives the loading arm 203f to rotate to the appropriate loading position. At the same time as the loading pump 203b is started, the electric valve 203g is automatically opened. The medium is input to the external transportation equipment through the loading arm 203f. After loading is completed, the loading pump 203b is turned off, and the electric valve 203g is automatically closed.

[0049] When it is necessary to discharge sewage from the recycling tank 103a, first remove the three-way pipe 201c, install the sewage discharge pipe, then open the sewage discharge gate valve 201b, and complete the sewage discharge operation through the sewage discharge pipeline 201a.

[0050] In summary, the skid 101 provides stable support and a solid foundation for installation. All functional components, including the recovery tank 103a, are mounted on its top. No complex on-site civil engineering is required; the skid can be directly transported to the work site via the lifting lug 106 and quickly put into use, effectively avoiding the environmental impact of excavation work. Through the coordinated operation of the main structure 100 and the transmission mechanism 200, efficient recovery, processing, and loading of the vented medium are achieved. The pipe-type separator 201g of the liquid inlet assembly 201 separates the vented medium into oil and gas. The separated oil droplets enter the recovery tank 103a, while the gas is discharged through the flame arrestor breather valve 103d. The oil delivery assembly 202 and the loading assembly 203 work together to achieve this. The system completes the external transport of the medium, effectively solving the problem of transportation limitations in traditional venting medium recovery. The lifting component 203d and the loading arm rotating component 203e work together to achieve position adjustment of the loading arm 203f, ensuring that the device always maintains a high-efficiency operating state and significantly improving the efficiency and safety of venting operations. The auxiliary component storage box 105 can store components that are prone to exceeding height limits, such as the flame arrester breather valve 103d, during transportation. The split-type protective cage 104a can be disassembled and combined, and the folding guardrail 104c can be folded, effectively reducing the height of the device during transportation. The height and angle of the loading arm 203f can be adjusted by the lifting component 203d and the loading arm rotating component 203e, effectively avoiding the problem of exceeding length and height limits during transportation.

[0051] Example 2

[0052] Reference Figure 1-2 and Figure 4-5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a monitoring component 204 for the device, which can monitor and adjust various data during the use of the device, ensuring the safe use of the device and providing data support for oil well production capacity prediction.

[0053] Specifically, the monitoring component 204 includes a temperature transmitter 204a located at the lower end of one side of the recovery tank 103a, two electric heating rods 204b symmetrically located on the other side of the recovery tank 103a, a magnetic float level gauge 204c located on one side of the recovery tank 103a, an inlet pressure transmitter 204d located on the discharge process manifold tee 202d, a pressure transmitter 204e located on the oil pump 202e, a flow meter 204f installed on the inlet pipeline 201e, and a magnetostrictive level gauge 204g located at the top of the recovery tank 103a.

[0054] It should be noted that the magnetic float level gauge 204c installed on the top of the recovery tank 103a is interlocked with the electric ball valve 201d on the inlet pipeline 201e. The electric ball valve 201d closes when the liquid level is high and opens when the liquid level is low. The temperature transmitter 204a at the lower end of one side of the recovery tank 103a is interlocked with the electric heating rod 204b at the lower right end of the recovery tank 103a. It automatically opens when the temperature is below 60°C and automatically closes when the temperature is above 60°C. The loading pump 203b is interlocked with the loading arm 203f. The electric valve 203g at the end outlet is interlocked. When the loading pump 203b starts, the electric valve 203g opens, and when the loading pump 203b closes, the electric valve 203g closes. The amount of nitrogen injected into the formation is known by the flow meter on the nitrogen injection pump outlet pipeline, but the amount released is unknown. The flow meter 204f can be used to calculate the nitrogen discharge volume and determine the gas column height at the downhole oil and gas interface, providing a basis for predicting the oil well's production capacity. The control cabinet 107 is used to control the start and stop of the two pump motors.

[0055] During operation, temperature transmitter 204a monitors the temperature of the medium inside the tank in real time. When the temperature is below 60°C, electric heating rod 204b automatically starts heating. When the temperature is above 60°C, electric heating rod 204b automatically shuts off to ensure the medium is in a suitable state. Magnetic level gauge 204c monitors the liquid level in recovery tank 103a in real time. When the liquid level reaches a high level, electric ball valve 201d automatically shuts off. When the liquid level drops to a low level, electric ball valve 201d automatically opens to ensure the safe operation of the device. At the same time, flow meter 204f accurately measures the medium flow rate, providing data support for determining the height of the gas column at the downhole oil and gas interface. During the medium transportation process, inlet pressure transmitter 204d and oil pump 202e work together with pressure transmitter 204e to monitor the manifold pressure in real time, ensuring a stable and safe oil transportation process.

[0056] In summary, the interlocking design of the components in the monitoring module 204 effectively improves the intelligence level of the device and enhances the convenience of operation. It effectively solves the problems of cumbersome operation and difficult safety control when recovering traditional venting media. The flow meter 204f can also provide data support for oil well production capacity prediction. Through the cooperation of the above structures, the effective operation and control of the device can be achieved without complicated manual operation, thus extending the service life of the device.
