Description

Technical Field

[0001] This utility model relates to the technical field of skid-mounted equipment for oil fields, specifically a skid-mounted mechanism for purifying associated gas in oil fields. Background Technology

[0002] Associated gas in oil fields refers to natural gas that overflows from oil reservoirs along with oil during oil extraction. Direct combustion of associated gas in oil fields will cause greenhouse gas emissions and energy waste. Therefore, it is necessary to use skid-mounted purification equipment to treat associated gas in oil fields. The skid-mounted mechanism in oil fields is a modular integrated device that pre-installs the equipment, pipelines, valves, control systems, etc. required for oil field production on a metal frame, forming a functional unit that can be transported as a whole and deployed quickly.

[0003] Currently, common skid-mounted purification systems for associated gas in oil fields pose a safety hazard due to gas leakage. Because there are many pipe connections inside the skid-mounted system, gas leakage can easily occur if the sealing of some pipe connections is poor, thereby affecting the safety and stability of the skid-mounted system.

[0004] There is an urgent need for a skid-mounted mechanism for purifying associated gas in oil fields to address the technical deficiencies mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a skid-mounted mechanism for purifying associated gas in oil fields, so as to solve the problem of pollution caused by gas leakage mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a skid-mounted mechanism for purifying associated gas in oilfields, comprising a support base, an adjusting seat at the top of the support base, a protective railing fixedly connected to the periphery of the top of the adjusting seat, metal frames fixedly connected to both sides of the top of the adjusting seat, mounting brackets fixedly connected to both sides inside the metal frames, a deacidification device and a dehydration processor respectively fixedly mounted on the mounting brackets, a gas pretreatment device fixedly mounted at the top of the adjusting seat, a gas transmission pipe fixedly connected to the right side of the gas pretreatment device, and a gas transmission pipe fixedly connected to the left side of the dehydration processor. The device is equipped with a fixed gas outlet pipe. A controller is installed on the left side of the metal frame. An installation pipe is fixedly connected to the top of the gas pretreatment equipment. A connecting pipe is fixedly installed on the installation pipe. The connecting pipe is connected to the gas inlet pipe of the deacidification equipment. A detection cover is installed outside the connection of the connecting pipe. A gas sensor is fixedly connected inside the detection cover. A connecting ring is fixedly connected to the top of the detection cover. A fixing bolt is provided on the connecting ring. A reserved groove is provided inside the support base. A hydraulic cylinder is movably connected to the bottom of the reserved groove. A level is fixedly installed at the bottom of the adjustment base.

[0007] As a further technical solution of this utility model, the connecting ring is installed on the outside of the connecting pipe and is fixedly connected by fixing bolts.

[0008] As a further technical solution of this utility model, the gas sensor is electrically connected to the controller, and the controller is equipped with an alarm module.

[0009] As a further technical solution of this utility model, the two sides of the bottom end of the adjusting seat are fixedly connected to the limiting slide rails, and the output end of the hydraulic cylinder is movably connected to the limiting slider, which is embedded in the limiting slide rails in a sliding connection.

[0010] As a further technical solution of this utility model, the mounting bracket is provided with mounting bolts, the threads of which penetrate the mounting plate on the deacidification equipment and the dehydration processor and are fixedly connected to the metal frame.

[0011] As a further technical solution of this utility model, the deacidification device is arranged below the dehydration processor, and the deacidification device and the dehydration processor are connected by a pipeline.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the associated gas purification skid-mounted mechanism not only realizes the function of intelligent monitoring to improve purification safety and the function of easy adjustment and installation stability, but also realizes the function of reducing the footprint and facilitating assembly.

[0013] (1) By setting up a gas pretreatment device, a deacidification device and a dehydration processor, a detection hood, a gas sensor, a connecting ring and fixing bolts, when treating associated gas, the gas pretreatment device treats it by centrifugal sedimentation, and the hydrate structure can be destroyed by heating or throttling. Then it enters the deacidification device for deacidification treatment. Finally, after being treated by the dehydration processor, the gas can be transported. During the treatment process, detection hoods are installed at the pipe connections used for gas transportation. The gas sensor inside the detection hood can detect gas leakage in time. Once gas is detected, the data is transmitted to the controller to realize timely alarm. This structure improves the safety of the skid-mounted mechanism.

[0014] (2) By setting up a support seat, adjusting seat, limit slide, reserved groove, hydraulic cylinder and level, some ground areas have low flatness during use. When installing the equipment, first install the support seat in the designated area, and then judge the level status according to the level on the adjusting seat. The level status of the adjusting seat can be adjusted by independently adjusting two sets of hydraulic cylinders to maintain the stability of the equipment.

[0015] (3) By setting up an adjustment seat, guardrail, metal frame, mounting bracket and mounting bolt, the gas pretreatment equipment, deacidification equipment and dehydration processor on the skid-mounted mechanism are arranged vertically from bottom to top. The vertical mounting on the metal frame by the mounting bracket can reduce the floor space. Moreover, the gas pretreatment equipment, deacidification equipment and dehydration processor can be removed from the metal frame to form independent modules for use. This structure realizes the functions of reducing floor space and facilitating assembly. Attached Figure Description

[0024] Specifically, such as Figure 1 and Figure 2 As shown, the gas pretreatment device 6 treats the associated gas by centrifugal sedimentation, and the hydrate structure can be destroyed by heating or throttling. Then, it enters the deacidification device 8 for deacidification treatment. Finally, after being processed by the dehydration processor 10, the gas can be transported.

Once gas is detected, the data is transmitted to the controller 5 to realize timely alarm. The gas pretreatment equipment 6, deacidification equipment 8 and dehydration processor 10 on the skid-mounted mechanism are arranged vertically from bottom to top. They are vertically installed on the metal frame 4 by the mounting bracket 18 to reduce the footprint. Moreover, the gas pretreatment equipment 6, deacidification equipment 8 and dehydration processor 10 can be removed from the metal frame 4 to form independent modules for use. When using the equipment, some ground areas have low flatness. When installing the equipment, first install the support base 1 in the designated area, and then judge the level status according to the level 17 on the adjusting seat 2.
