Description

Technical Field

[0001] This utility model relates to the technical field of oilfield production equipment, specifically to a slider-driven associated oil and gas pressurization and transportation device. Background Technology

[0002] The oilfield has 23,830 wells. Due to the influence of extraction time and geological factors, 60% of the wells produce less than 200 m3 of associated gas per day. In order to solve the problem of low casing gas volume during oil production, the existing recovery device is too expensive. The original method of connecting the oil and casing only allows gas to enter the pipeline when the casing pressure is greater than the oil pressure. The casing pressure on site is generally between 0.6-1.0 MPa, which affects production. If the gas is released, it will waste resources and pollute the environment. In addition, Shengli Oilfield has more than 1,500 crude oil storage tanks and multi-functional tanks. About 60% of these tanks have a daily volatile gas volume of less than 200 m3. The original piston compressors and screw compressors used for these tanks had large suction pressure pulses, which caused frequent start-ups and shutdowns, making the equipment prone to damage and unable to operate normally. The volatile gas was dispersed into the atmosphere, causing environmental pollution. They were also expensive. More importantly, neither type of compressor allows liquid to enter the compressor. However, the associated gas in the field contains impurities such as water and light oil. In some oil wells, the fluid level is at the wellhead, making it easy for oil to enter and damage the equipment. Based on the above problems, the oilfield urgently needs a high-efficiency, stable, inexpensive associated gas pressurization device that is not afraid of water ingress.

[0003] Currently, in order to reduce natural gas emissions, methods such as oil-casing connection are often used to recover and utilize casing gas. However, due to the low casing gas pressure and excessive back pressure, the casing gas cannot enter the oil gathering trunk line. When measuring the liquid level, the casing gas is discharged into the atmosphere, which seriously pollutes the environment and wastes resources. In some wells, the excessively high casing gas pressure has affected the oil pump. In order to prevent the excessive casing pressure from affecting the oil pump, it is necessary to release the casing gas periodically to reduce the impact of the gas on the oil pump. As a result, the casing gas is discharged into the atmosphere, which seriously pollutes the environment.

[0004] Announcement No. CN202165248U discloses a hydraulic piston natural gas compressor, including a base and a main unit, a hydraulic station, a cooling system, and a process gas system mounted on the base. The hydraulic station and the cooling system are located at opposite ends of the base and are connected through the process gas system. The main unit is located between the hydraulic station and the cooling system and is connected to both of them through the process gas system. The main unit consists of two vertical cylinders, and the base is a skid.

[0005] The existing technology uses a hydraulically driven piston, which then compresses the natural gas, resulting in low efficiency. The two vertical cylinders further reduce efficiency. In contrast, this patented design uses a slider mechanism to directly drive the piston, compressing the natural gas with high efficiency.

[0006] Announcement No. CN214887601U discloses a piston-type natural gas compressor, including a fixed housing. A set of transverse slide rails is fixedly connected to both the front and rear sides of the bottom wall inside the fixed housing. The two sets of transverse slide rails are slidably connected to two sets of sliding blocks. By starting an added drive motor, the motor drives a drive screw fixed to its output shaft to rotate. The rotation of the screw causes a threaded nut block to move laterally. This lateral movement of the nut block, in turn, causes the mounting bracket containing the compressor body to move outwards from the fixed housing under the action of the added transverse slide rails and sliding blocks. Two sets of sliding cylinders are added to the bottom of the arc-shaped support sliding seat, slidably connected to the support column inside the bottom wall of the mounting bracket. A retaining spring is also added to the bottom of the sliding cylinders. When the fixed compressor body vibrates, the sliding cylinders move longitudinally on the support column.

[0007] The existing technology uses a motor to drive a screw to rotate, which in turn drives the threaded nut block to move laterally and then compress the natural gas. This results in a short service life for the nut. In contrast, this patented design uses a crank to drive a slider to directly drive the piston, resulting in a long service life.

[0008] Announcement No. CN205743857U discloses a hydraulic feedback type casing gas recovery device, including a gas compression cylinder, a spring, and a piston. One end of the gas compression cylinder is connected to an oil pipeline via a back pressure pipe, and the other end is connected to a drain cylinder. The gas compression cylinder is equipped with an inlet pipe and an exhaust pipe. The spring is disposed within the gas compression cylinder. One end of the piston is disposed within the gas compression cylinder and abuts against the spring. The other end of the piston is disposed within the drain cylinder. The drain cylinder is connected to an inlet pipe and is equipped with a drain pipe. Both the drain pipe and the exhaust pipe are connected to the oil pipeline. A drain check valve is disposed on the drain pipe. An inlet check valve is disposed on the inlet pipe, and an exhaust check valve is disposed on the exhaust pipe.

[0009] The prior art differs from the design concept of this patent. The prior art achieves the recovery of casing gas through hydraulic feedback, which results in a small amount of gas recovery. In contrast, this patent design uses a crank to drive a slider to directly drive the piston, resulting in a high amount of gas recovery.

[0010] In summary, the technical solutions, technical problems to be solved, and beneficial effects of the above-disclosed technologies are all different from those of this utility model. For more technical features, technical problems to be solved, and beneficial effects of this utility model, the above-disclosed technical documents do not provide any technical inspiration.

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.

[0050] Example 1:

The slider support 40 has an inner slide rail 39 inside, and the slider 38 is disposed in the inner slide rail 39. The slider 38 can slide along the inner slide rail 39. The slider 38 and the active power rocker arm 34 are rotatably connected through a connecting shaft 37. The slider 38 and the connecting shaft 37 are rotatably connected, or the active power rocker arm 34 and the connecting shaft 37 are rotatably connected. The slider 38 rotates around the output shaft of the drive mechanism while sliding back and forth along the inner slide rail 39, converting the rotational motion of the output shaft of the drive mechanism into the linear motion of the reciprocating intake and exhaust unit drive rod.

[0053] Specifically, the slider 38 is made of copper alloy, which has high strength and good sliding performance. The slider 38 is connected by a connecting shaft 37 and adopts a bearingless design, which has a bearing life of more than three times.

[0054] Specifically, the slider bracket 40 and the main power rocker arm 34 are made of 65# manganese quenching and tempering, which ensures the strength of mechanical transmission and friction loss. Compared with traditional compressors, they have the characteristics of high efficiency, low failure rate and long service life.

[0055] Furthermore, the reciprocating intake and exhaust unit includes a cylinder 5, a piston 32, and a piston rod 36. The piston 32 is slidably sealed inside the cylinder 5. The piston rod 36 is threadedly connected to the piston and extends out of the cylinder 5. The piston rod 36 is the drive rod. The piston rod 36 is connected to the slider bracket 40 through a piston connecting rod flange 41. The end of the cylinder 5 away from the piston rod 36 is connected to the intake and exhaust stabilizing mechanism.

[0056] Specifically, the piston 32 is made of corrosion-resistant austenitic alloy and consists of a double gas seal plus a wear-resistant sleeve oil seal, featuring high pressure resistance, corrosion resistance, and wear resistance.

[0058] Specifically, the cylinder 5 is forged from an austenitic alloy, which has the characteristics of high metal density, good compressive strength, and strong wear and corrosion resistance.

[0059] Specifically, the piston rod 36 adopts a direct connection method, which reduces the gap between various mechanical parts, ensures that the compressed gas is completely discharged, minimizes the elasticity of the compressed gas, and improves the compression efficiency.

[0060] Furthermore, the intake and exhaust stabilization mechanism includes an intake pressure regulator 10 and an exhaust pressure regulator 12; the intake pressure regulator 10 is connected to the cylinder 5 through an intake pipe 13, and an intake one-way valve 8 is provided on the intake pipe 13; the exhaust pressure regulator 12 is connected to the cylinder 5 through an exhaust pipe 14, and an exhaust one-way valve 7 is provided on the exhaust pipe 14; the intake pressure regulator 10 is provided with an intake port 17, and an intake valve 15 is provided on the intake port 17; the exhaust pressure regulator 12 is provided with an exhaust port 18, and an exhaust valve 16 is provided on the exhaust port 18.

[0061] Among them, the intake pressure regulator 10 and the outlet pressure regulator 12 play the role of stabilizing the air pressure, ensuring that the pressure at the intake port 17 and the outlet port 18 is stable, and ensuring the normal operation of the compressor. The intake check valve 8 and the outlet check valve 7 play the role of stabilizing the airflow direction.

[0062] Specifically, the intake check valve 8 and the exhaust check valve 7 are made of corrosion-resistant materials.

[0063] Specifically, the intake pressure regulator 10 is equipped with an intake pressure sensor 9, and the outlet pressure regulator 12 is equipped with an outlet pressure sensor 11 to detect the intake pressure and outlet pressure.

[0064] Furthermore, the drive mechanism includes an explosion-proof motor 1 and a multi-stage reducer 2. The output shaft of the explosion-proof motor 1 is connected to the input shaft of the multi-stage reducer 2, and the output shaft of the multi-stage reducer 2 is connected to the end of the main force rocker arm 34 away from the slider via a key.

[0065] Furthermore, two reciprocating intake and exhaust units are provided. The piston rods 36 of the two reciprocating intake and exhaust units are located at opposite ends of the slider bracket 40. The cylinders 5 of the two reciprocating intake and exhaust units are connected to the intake and exhaust stabilizing mechanism, so that intake and exhaust are continuous.

[0066] Example 2:

[0067] Based on Embodiment 1, this embodiment adds a lubrication mechanism, which includes a mechanical housing 20. The multi-stage reducer 2 is sealed to the mechanical housing 20 via a reducer connecting plate 3. The cylinder 5 is sealed to the mechanical housing 20 via a cylinder connecting flange 4. The slider carriage transmission mechanism is located inside the mechanical housing 20. The mechanical housing 20 is filled with lubricating oil, which serves to lubricate, dissipate heat, and seal. A flow passage is provided between the slider bracket and the mechanical housing 20. The annular space between the piston rod 36 and the cylinder 5 is connected to the interior of the mechanical housing 20 via a piston lubrication oil passage 31. An oil seal 43 is provided on the outer wall of the piston 32 near the end of the mechanical housing 20. An independent lubrication system is provided, with the lubrication of the mechanical housing 20 isolated from that of the multi-stage reducer 2. The piston lubrication oil passage 31 inside the mechanical housing 20 provides cooling and lubrication for the piston 32, ensuring normal piston lubrication.

[0068] Specifically, the mechanical housing 20 is made of 65# manganese plate with heat treatment, which maximizes the tortuosity of the stress points of the housing. The housing is designed with piston lubrication oil passage 31, which uses the piston's back and forth pushing and pulling motion to drive the lubricating oil to lubricate the piston.

[0069] Specifically, the intake and exhaust ends of cylinder 5 are far from the mechanical housing 20, which greatly reduces the temperature inside the mechanical housing 20, ensuring that the components do not overheat and significantly improving their service life.

[0070] Furthermore, the slider bracket 40 is provided with a flow hole to reduce the movement resistance of the slider bracket 40 within the mechanical housing 20, so that the lubricating oil can fully lubricate the slider carriage transmission mechanism.

[0071] Example 3:

[0072] Based on Embodiment 2, this embodiment adds a cooling mechanism, which includes a cylinder water-cooled radiator 6, a coolant tank 25, a cooling circulation pump 26, and a coolant radiator 29. The cylinder water-cooled radiator 6 has an inner cavity sleeve and is provided with a first liquid port 21 and a second liquid port 22 that are far apart. Two cylinder water-cooled radiators 6 are provided and are respectively fitted onto the outer walls of two cylinders 5. The two second liquid ports 22 are connected by a series cooler pipeline 23. The cooling circulation pump 26 is connected to one of the first liquid ports 21 through a coolant inlet pipeline 27. The coolant radiator 29 is connected to the other first liquid port 21 through a coolant return pipeline 24. Both the cooling circulation pump 26 and the coolant radiator 29 are connected to the coolant tank 25, which is provided with a coolant filling port 28. The coolant radiator 29 can effectively reduce the temperature of the cylinders 5, reduce the aging of the piston seals due to heat during gas compression, and ensure safe and efficient recovery of oil and gas.

[0073] Specifically, the coolant radiator 29 is connected to the crude oil pipeline heating system to heat the crude oil, thereby realizing the utilization of waste heat.

[0074] Specifically, the explosion-proof motor 1 and the cooling circulation pump 26 are both electrically connected to the motor driver.

[0075] Specifically, the cylinder water-cooled radiator 6 is equipped with a temperature sensor 19.

[0076] During operation, the air inlet 17 is connected to the casing, and the air outlet 18 is connected to the process flow. The output shaft of the explosion-proof motor 1 rotates, and after being reduced in speed by the multi-stage reducer 2, it drives the main power rocker arm 24 to rotate. The main power rocker arm 24 drives the slider 38 inside the slider bracket 40 to move up and down in the inner slide rail 39 of the slider bracket 40 through the connecting shaft 37, which in turn drives the slider bracket 40 to move left and right. The slider bracket 40 drives the piston rod 27 and the piston 26 to move back and forth. When the slider bracket 40 moves to the left, it compresses the gas in the left cylinder 5, and the right cylinder 5 completes the intake process. When it moves to the right, it compresses the gas in the right cylinder 5, and the left cylinder 5 completes the intake process. This cycle repeats to complete the intake and exhaust process, pressurizes the casing oil and gas, and forces it into the process flow to complete the recovery of casing gas. The mechanical housing 20 is filled with lubricating oil, which flows into the cylinder 5 through the piston lubrication oil passage 31 for lubrication. The heat generated by the cylinder 5 during the intake and exhaust process is dissipated through the cylinder heat sink 6.

[0077] Example 4:

[0078] Based on Embodiment 3, this embodiment adds an explosion-proof electrical box 49. The explosion-proof electrical box 49 is equipped with a touch screen and a remote control module 48. The remote control module is connected to the temperature sensor 19, the inlet pressure sensor 9, the outlet pressure sensor 11, and the motor driver through the antenna 50. The touch screen displays temperature, pressure, speed of the explosion-proof motor 1, and speed of the cooling circulation pump 26. The touch screen and the remote control module 48 send commands to the motor driver to control the explosion-proof motor 1 and the cooling circulation pump 26, thereby controlling the pressure and temperature.

[0079] Specifically, the explosion-proof electrical box 49 is also equipped with an outlet temperature gauge 44, an inlet temperature gauge 45, an inlet pressure gauge 46, and an outlet pressure gauge 47 to prevent the touch screen from malfunctioning and being unable to view the working status.

[0080] Specifically, the remote control module can be a PLC programmable controller.

[0081] It should be noted that the touch screen and remote control module 48, the motor driver, the temperature / pressure sensor, and the motor / pump are all existing technologies, which are clear to those skilled in the art.
