Description

Technical Field

[0001] This invention relates to the field of oil-gas-water separation device technology, specifically a high-efficiency adaptive oil-gas-water separation and mixing skid device. Background Technology

[0002] The oil-gas-water separation and mixing skid unit is an integrated, modular, and highly efficient processing device, mainly used in oil and gas field development and gathering and transportation systems for the integrated processing of oil, gas, and water three-phase mixtures for separation, pressure regulation, metering, and mixing.

[0003] Currently, during the transmission of oil, gas, and water mixtures, the feed pipe of the three-phase separator has bends. These bends are prone to changes in fluid flow, pressure, and the generation of bubbles. These bubbles can accelerate the accumulation of oil and sludge in the bend area, affecting the transmission rate of the mixture. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency adaptive oil-gas-water separation and mixing skid device. A second portion of hot air is transmitted to the interior of the heating jacket through a second pipe to heat the feed pipe of the three-phase separator. This prevents the formation of bubbles when the oil-gas-water mixture is transported to the bend. The movement trajectory and distribution of the bubbles will affect the deposition location of oil in the pipe, causing the oil to concentrate and deposit in the bend area, forming a thicker oil layer and affecting the transport rate of the mixture.

[0006] The three-phase separator is equipped with a cleaning assembly, which includes a storage tank. One side of the storage tank is connected to one of the output ends of a U-shaped tube. A push plate is slidably installed inside the storage tank. A moving rod is slidably connected to one side of the push plate. A magnetic block is fixedly connected to one end of the moving rod. A cleaning tank is connected to the lower end of the storage tank. A float plate is slidably installed inside the cleaning tank. A first nozzle and a second nozzle are connected to one side of the cleaning tank. One end of the first nozzle and the second nozzle are connected to both sides of the three-phase separator. An anti-corrosion box is installed on one side of the storage tank. One side of the anti-corrosion box is connected to the cleaning box.

[0007] Preferably, both sets of output ends of the U-tube are connected to one side of the three-phase separator, and one set of output ends of the U-tube is connected to the storage tank and the first pipe, while the other set of output ends of the U-tube is externally connected to a heat exchanger.

[0008] Preferably, the other end of the first pipe is connected to a second pipe, one end of the second pipe is connected to a heating jacket, the heating jacket is set outside the feed pipe of the three-phase separator, and one end of the heating jacket is provided with an exhaust port.

[0009] Preferably, a spring is fixedly connected to one side of the storage box, and one end of the spring is connected to the inner wall of the storage box.

[0010] Preferably, the movable rod has protrusions at both ends, a slider on one side of the movable rod, and three sets of sliding grooves at the bottom of the storage box, with the protrusions and sliders slidably connected to the sliding grooves.

[0011] Preferably, a first through hole is provided between the storage box and the cleaning box, the magnetic block is slidably connected to the first through hole, and a magnetic sealing ring is provided at the connection between the magnetic block and the first through hole.

[0012] Preferably, a push rod is fixedly connected to one side of the storage box, one end of the push rod penetrates one side of the anti-corrosion box, and one end of the push rod is connected to a block through a connecting rod.

[0013] Preferably, a fifth pipe is connected to one side of the corrosion-resistant box, one end of the fifth pipe is connected to the cleaning box, and the plug is slidably connected to one end of the fifth pipe.

[0014] Preferably, the cleaning box is provided with a limiting block inside, a third pipe is connected to one side of the storage box, the two ends of the storage box are respectively connected to a first spray pipe and a second spray pipe, the other end of the second spray pipe is connected to a fourth pipe, and a nozzle is provided at one end of the fourth pipe.

[0015] Preferably, a feed pipe is provided on both sides of the cleaning box and one side of the anti-corrosion box. Valves are provided on the feed pipes on both sides of the cleaning box, the feed pipe on one side of the anti-corrosion box, and the fourth pipe. One-way valves are provided at the connection between the fifth pipe and the cleaning box and at the connection between the U-shaped pipe and the storage box.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, the hot air in the second part is transmitted to the interior of the heating jacket through the second pipe to heat the feed pipe of the three-phase separator. This prevents the formation of bubbles when the oil-gas-water mixture is transmitted to the bend. The movement trajectory and distribution of the bubbles will affect the deposition location of the oil in the pipe, causing the oil to concentrate and deposit in the bend area, forming a thicker oil layer, which affects the transmission rate of the mixture.

[0018] 2. In this invention, the cleaning agent is delivered to the first and second spray nozzles via a third pipe. The first and second spray nozzles then deliver the cleaning agent to the three-phase separator, where it cleans and separates any remaining impurities. The impurities are then discharged through the drain port of the three-phase separator, reducing the cleaning cycle for construction personnel and alleviating their workload. Traditional three-phase separators require construction personnel to enter the separator through a manhole for cleaning, which is a frequent and tedious process.

[0019] 3. In this invention, a portion of the corrosion inhibitor is transported along with the cleaning agent through the second spray pipe to the inside of the fourth pipe. The fourth pipe then sprays the agent onto the outer surface of the three-phase separator through a nozzle at one end, providing corrosion protection for the three-phase separator. This prevents the three-phase separator from being exposed to harsh weather conditions such as wind, sun, rain, and frost when it is installed outdoors, thus accelerating its aging and corrosion and shortening its service life.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] See Figures 1 to 4 As shown, the present invention provides a high-efficiency adaptive oil-gas-water separation and mixing skid device, including a three-phase separator 1, an auxiliary component 2 installed on the three-phase separator 1, the auxiliary component 2 including a U-shaped tube 201, the U-shaped tube 201 installed inside the three-phase separator 1, the U-shaped tube 201 having two sets of output ends, one set of output ends of the U-shaped tube 201 being connected to a first pipe 203, one end of the first pipe 203 being connected to a liquid flow stabilizing baffle inside the three-phase separator 1, and one side of the first pipe 203 being connected to a heating jacket 205;

[0031] When the oil-water-gas mixture passes through the transmission pipe on one side of the three-phase separator 1, it is transported to the interior of the three-phase separator 1 of the mixing skid device for sedimentation and separation. Then, the construction personnel start the external heat exchanger of the U-tube 201. The heat exchanger transmits hot air into the U-tube 201 for circulation, heating the oil-water-gas mixture inside the three-phase separator 1. The increase in temperature will reduce the viscosity of oil and water. The viscosity of oil decreases significantly with the increase in temperature, and the viscosity of water will also decrease. After the viscosity decreases, the resistance to movement of oil droplets and water droplets in the medium is reduced, making it easier for them to collide and coalesce, thereby efficiently and adaptively accelerating the separation speed.

[0032] When the heat exchanger circulates hot gas into the U-tube 201, the hot gas is discharged from the output end of the other end of the U-tube 201. Part of the discharged hot gas is transmitted through the first pipe 203, and the second pipe 204 divides the hot gas into two parts. The first part of the hot gas is transmitted to the liquid flow stabilizing baffle inside the three-phase separator 1 to soften the oil on the liquid flow stabilizing baffle and reduce the adhesion of the scale. When the oil-water-gas mixture is transmitted to the three-phase separator 1 of the mixing skid device for sedimentation and separation, it needs to pass through the liquid flow stabilizing baffle inside the three-phase separator 1 to reduce the fluid flow rate of the mixture. The mixture carries oil, and the adhesion of the oil on the liquid flow stabilizing baffle increases, resulting in increased scale strength, which in turn affects the flow rate of the mixture.

[0033] Because the oil-gas-water mixture has bends in its feed pipe during transport, these bends cause changes in fluid flow, pressure, and the generation of bubbles. These bubbles accelerate oil buildup in multiple ways. A second portion of hot gas is transferred through the second pipe 204 to the heating jacket 205 to heat the feed pipe of the three-phase separator 1, preventing the formation of bubbles when the oil-gas-water mixture reaches the bends. The trajectory and distribution of these bubbles affect the deposition location of oil buildup in the pipe.

[0034] This causes oil stains to accumulate in the bending area, forming a thicker oil stain layer, which affects the transmission rate of the mixture. One end of the heating jacket 205 is equipped with an exhaust port 206, which exhausts the hot air inside the heating jacket 205 to the outside, maintaining the stable air pressure inside the heating jacket 205. The hot air is mainly low-temperature waste heat generated by the operation of the equipment, and its components are mainly water vapor and air. It does not contain toxic or harmful substances and will not cause pollution to the environment after being discharged.

[0035] See Figures 5 to 8 As shown, a cleaning assembly 3 is installed on the three-phase separator 1. The cleaning assembly 3 includes a storage box 301. One side of the storage box 301 is connected to one of the output ends of the U-shaped tube 201. A push plate 302 is slidably installed inside the storage box 301. A moving rod 304 is slidably connected to one side of the push plate 302. A magnetic block 305 is fixedly connected to one end of the moving rod 304. A cleaning box 309 is connected to the lower end of the storage box 301. A float plate 320 is slidably installed inside the cleaning box 309. A first nozzle 311 and a second nozzle 312 are connected to one side of the cleaning box 309. One end of the first nozzle 311 and the second nozzle 312 are connected to both sides of the three-phase separator 1. A corrosion-resistant box 314 is installed on one side of the storage box 301. One side of the corrosion-resistant box 314 is connected to the cleaning box 309.

[0036] Hot air is discharged from the output end of the other end of the U-shaped tube 201. A portion of the discharged hot air is transferred to the inside of the storage box 301, where it accumulates and compresses the push plate 302, causing it to move within the storage box 301. During this time, hot air continues to be output, and the pressure of the hot air exceeds the elastic force of the spring 303, compressing the spring 303. When the push plate 302 moves to the position of the protrusion at one end of the moving rod 304, it drives the moving rod 304 to move. The moving rod 304 then drives the magnetic block 305 at one end to move. When the push plate 302 moves the moving rod 304 to the end of the chute, the moving rod 304 causes the magnetic block 305 to move away from the storage box 301 and away from the cleaning... At the first through hole provided between the boxes 309, the hot air inside the storage box 301 is transferred to the cleaning box 309 through the first through hole. At this time, the sedimentation separation work inside the three-phase separator 1 is also completed, the heat exchanger stops working and transfers hot air, and the hot air no longer pushes the push plate 302 to move. As a result, the elastic force of the spring 303 is greater than the pressure of the hot air, the spring 303 drives the push plate 302 to rebound and reset. The push plate 302 pushes the hot air inside the storage box 301, and the auxiliary hot air is transferred to the cleaning box 309 through the first through hole. The other end of the U-tube 201 is provided with a one-way valve 318 to prevent the hot air from flowing back into the U-tube 201 and affecting the normal operation of the U-tube 201.

[0037] When hot air is transferred into the cleaning box 309 through the first through hole, the hot air pushes the float 320 to move inside the cleaning box 309. The float 320 squeezes the cleaning agent inside the cleaning box 309. The cleaning agent is transferred to the first nozzle 311 and the second nozzle 312 through the third pipe 310. The first nozzle 311 and the second nozzle 312 then transfer the cleaning agent into the three-phase separator 1 to clean the remaining impurities after separation. The impurities are then discharged through the drain port of the three-phase separator 1, reducing the cleaning cycle of the construction personnel and reducing the workload of the workers. The traditional three-phase separator 1 requires the construction personnel to enter the three-phase separator 1 through the manhole to clean the three-phase separator 1. The cleaning work is relatively frequent and tedious.

[0038] When the push plate 302 returns to its original position following the spring 303, the push plate 302 will press the protrusion at the other end of the moving rod 304, thereby driving the magnetic block 305 to re-seal the first through hole between the storage box 301 and the cleaning box 309 through the moving rod 304, so as not to affect the next operation. A magnetic sealing ring 306 is provided at the connection between the magnetic block 305 and the first through hole to ensure that there is no air leakage when the first through hole is sealed.

[0039] Both sides of the cleaning tank 309 are equipped with feed pipes. When the float 320 squeezes the cleaning agent inside the cleaning tank 309, one side of the float 320 moves to a limiting block inside the cleaning tank 309 and stops moving. The cleaning agent is no longer transmitted, and the cleaning work is completed. At this time, the construction personnel open the valve 319 on one side of the feed pipe of the cleaning tank 309 to replenish the cleaning agent in the cleaning tank 309, which is convenient for the next work. Since the feed pipe on one side of the cleaning tank 309 is below the float 320, when the cleaning agent is replenished, the cleaning agent will push the float 320 to reset upward. At the same time, the valve 319 on the feed pipe on the other side of the cleaning tank 309 is opened, and the heat transmitted inside the cleaning tank 309 is transferred to the outside, preventing the heat transmitted inside the cleaning tank 309 from affecting the reset of the float 320, so as to carry out the next work.

[0040] If the mixing skid device is installed outdoors, the construction personnel open valve 319 on the feed pipe on one side of the corrosion-resistant box 314 to add corrosion inhibitor to the corrosion-resistant box 314. Then, when the exhaust hot air is discharged, another part is introduced into the storage box 301 to collect. At the same time, the air pressure pushes the push plate 302 to move inside the box, and the push plate 302 pushes the push rod 315 to move inside the corrosion-resistant box 314. The push rod 315 drives the block 316 away from the connection between the fifth pipe 317 and the corrosion-resistant box 314 through the connecting rod. The corrosion inhibitor inside the corrosion-resistant box 314 is transferred to the cleaning box 309 through the fifth pipe 317, mixes with the cleaning agent inside the cleaning box 309, and then flows through the cleaning agent. The cleaning agent is transmitted through the third pipe 310 to the first nozzle 311 and the second nozzle 312. Then, the construction personnel open the valve 319 on the fourth pipe 313. A portion of the corrosion inhibitor is then transmitted through the second nozzle 312 to the fourth pipe 313. The fourth pipe 313 is then sprayed onto the outer surface of the three-phase separator 1 through a nozzle at one end to provide corrosion protection for the three-phase separator 1. This prevents the three-phase separator 1 from being exposed to the natural environment when it is installed outdoors, where it would be affected by harsh weather conditions such as wind, sun, rain, and frost, which would accelerate the aging and corrosion of the three-phase separator 1 and shorten the service life of the equipment.

[0041] A one-way valve 318 is provided on the fifth pipe 317 to prevent the cleaning agent from flowing back into the fifth pipe 317 and affecting the transmission of the corrosion inhibitor in the fifth pipe 317.

[0042] In an optional embodiment, both sets of output ends of the U-tube 201 are connected to one side of the three-phase separator 1, and one set of output ends of the U-tube 201 is connected to the storage tank 301 and the first pipe 203, while the other set of output ends of the U-tube 201 is externally connected to a heat exchanger.

[0043] It should be noted that when the construction personnel start the external heat exchanger of the U-tube 201, the heat exchanger will transfer hot air into the U-tube 201 for circulation, which will heat the oil-water-gas mixture inside the three-phase separator 1. The hot air will be discharged from the output end of the other end of the U-tube 201. Part of the discharged hot air will be transferred through the first pipe 203, and the other part of the discharged hot air will be transferred to the storage tank 301.

[0044] In an optional embodiment, the other end of the first pipe 203 is connected to a second pipe 204, one end of the second pipe 204 is connected to a heating jacket 205, the heating jacket 205 is disposed outside the feed pipe of the three-phase separator 1, and one end of the heating jacket 205 is provided with an exhaust port 206.

[0045] It should be noted that the second part of the hot air is transferred to the heating jacket 205 through the second pipe 204 to heat the feed pipe of the three-phase separator 1. The exhaust port 206 discharges the hot air inside the heating jacket 205 to the outside, keeping the internal air pressure of the heating jacket 205 stable. The hot air is mainly low-temperature waste heat generated by the operation of the equipment, and its components are mainly water vapor and air. It does not contain toxic or harmful substances and will not cause pollution to the environment after being discharged.

[0046] In an optional embodiment, a spring 303 is fixedly connected to one side of the storage box 301, and one end of the spring 303 is connected to the inner wall of the storage box 301.

[0047] It should be noted that when the hot gas pressure pushes the push plate 302 to move, the spring 303 is compressed and stores energy. After the heat exchanger stops supplying gas, its elasticity drives the push plate 302 to spring back and reset, pushing the residual hot gas to be completely discharged. During the reset process, the spring 303 drives the magnetic block 305 to re-seal the first through hole through the moving rod 304, forming a double seal with the magnetic sealing ring 306 to prevent the cleaning agent from flowing back.

[0048] In an optional embodiment, the moving rod 304 has protrusions at both ends, a slider on one side of the moving rod 304, and three sets of sliding grooves at the bottom of the storage box 301, with the protrusions and sliders slidably connected to the sliding grooves.

[0049] It should be noted that when the push plate 302 is pushed and moved by the pressure of hot air, the protrusion on one side slides directionally along the slide groove, which not only ensures that the push plate 302 moves only along the preset path, but also precisely controls the end point of the push plate 302's stroke through the physical limit at the end of the slide groove. When the push plate 302 moves to the end of the slide groove, the protrusion just touches the corresponding protrusion at the end of the moving rod 304, driving the moving rod 304 to move axially, thereby driving the magnetic block 305 to disengage from the first through hole to open the gas passage. During the reset phase, the spring 303 pushes the push plate 302 to move in the opposite direction, and its protrusion is guided again by the slide groove, squeezing the protrusion on the other side of the moving rod 304 during the return stroke, forcing the magnetic block 305 to re-seal the through hole, forming a double seal with the magnetic sealing ring 306.

[0050] In an optional embodiment, a first through hole is provided between the storage box 301 and the cleaning box 309, the magnetic block 305 is slidably connected to the first through hole, and a magnetic sealing ring 306 is provided at the connection between the magnetic block 305 and the first through hole.

[0051] It should be noted that the magnetic sealing ring 306 is installed at the connection between the magnetic block 305 and the first through hole. Its function is to prevent gas or liquid leakage between the storage box 301 and the cleaning box 309 by magnetic attraction when the magnetic block 305 blocks the through hole.

[0052] In an optional embodiment, a push rod 315 is fixedly connected to one side of the storage box 301. One end of the push rod 315 passes through one side of the anti-corrosion box 314, and one end of the push rod 315 is connected to a block 316 via a connecting rod.

[0053] It should be noted that while the pneumatic pressure pushes the push plate 302 to move inside the box, the push plate 302 also pushes the push rod 315 to move inside the corrosion-resistant box 314.

[0054] In an optional embodiment, a fifth pipe 317 is connected to one side of the corrosion protection box 314, one end of the fifth pipe 317 is connected to the cleaning box 309, and the block 316 is slidably connected to one end of the fifth pipe 317.

[0055] It should be noted that the push rod 315 drives the block 316 away from the connection between the fifth pipe 317 and the anti-corrosion box 314 through the connecting rod. The anti-corrosion agent inside the anti-corrosion box 314 is transferred to the cleaning box 309 through the fifth pipe 317 and mixes with the cleaning agent inside the cleaning box 309.

[0056] In an optional embodiment, the cleaning box 309 is provided with a limiting block inside, the storage box 301 is connected to a third pipe 310 on one side, the two ends of the storage box 301 are respectively connected to a first nozzle 311 and a second nozzle 312, the other end of the second nozzle 312 is connected to a fourth pipe 313, and a nozzle is provided at one end of the fourth pipe 313.

[0057] It should be noted that a portion of the corrosion inhibitor is transported along with the cleaning agent through the second spray pipe 312 to the inside of the fourth pipe 313. The fourth pipe 313 is then sprayed onto the outer surface of the three-phase separator 1 through a nozzle at one end, thus providing corrosion protection for the three-phase separator 1.

[0058] In an optional embodiment, a feed pipe is provided on both sides of the cleaning box 309 and on one side of the anti-corrosion box 314. A valve 319 is provided on the feed pipes on both sides of the cleaning box 309, the feed pipe on one side of the anti-corrosion box 314, and the fourth pipe 313. A one-way valve 318 is provided at the connection between the fifth pipe 317 and the cleaning box 309 and at the connection between the U-shaped pipe 201 and the storage box 301.

[0059] It should be noted that the one-way valve 318 can prevent the backflow of liquids in the pipeline, such as cleaning agents and corrosion inhibitors, to avoid contamination or affecting the transmission. The valve 319 can be manually controlled for liquid replenishment, venting and corrosion inhibitor spraying to ensure normal operation and flexible operation of the device.

[0060] Working principle: When the oil-water-gas mixture passes through the transmission pipe on one side of the three-phase separator 1, it is transferred to the interior of the three-phase separator 1 of the mixing skid device for sedimentation and separation. Then, the construction personnel start the external heat exchanger of the U-tube 201. The heat exchanger transfers hot air into the U-tube 201 for circulation, heating the oil-water-gas mixture inside the three-phase separator 1.

[0061] When the heat exchanger circulates the hot gas into the U-tube 201, the hot gas is discharged from the output end of the other end of the U-tube 201. Part of the discharged hot gas is transmitted through the first pipe 203, and the second pipe 204 divides the hot gas into two parts. The first part of the hot gas is transmitted to the liquid flow stabilizing baffle inside the three-phase separator 1.

[0062] During the transmission of the oil-gas-water mixture, there are bends in the feed pipe of the three-phase separator 1. At the bends in the pipe, the fluid flow state changes, pressure changes, and bubbles are generated. Moreover, the bubbles accelerate the formation of oil stains from multiple aspects. The second part of the hot air is transmitted to the heating jacket 205 through the second pipe 204 to heat the feed pipe of the three-phase separator 1.

[0063] Hot air is discharged from the output end of the other end of the U-shaped tube 201. A portion of the discharged hot air is transferred to the inside of the storage box 301, where it accumulates and compresses the push plate 302, causing it to move within the storage box 301. During this time, hot air continues to be output, and the pressure of the hot air exceeds the elastic force of the spring 303, compressing the spring 303. When the push plate 302 moves to the position of the protrusion at one end of the moving rod 304, the push plate 302 drives the moving rod 304 to move. The moving rod 304 then drives the magnetic block 305 at one end to move. When the push plate 302 drives the moving rod 304... When the push plate moves to the end of the chute, the moving rod 304 drives the magnetic block 305 away from the first through hole between the storage box 301 and the cleaning box 309. The hot air inside the storage box 301 is transferred to the cleaning box 309 through the first through hole. At this time, the sedimentation separation work inside the three-phase separator 1 is also completed. The heat exchanger stops working and transfers hot air. The hot air no longer pushes the push plate 302 to move. As a result, the elastic force of the spring 303 is greater than the pressure of the hot air. The spring 303 drives the push plate 302 to rebound and reset. The push plate 302 pushes the hot air inside the storage box 301.

[0064] When hot air is transferred into the cleaning tank 309 through the first through hole, the hot air pushes the float 320 to move inside the cleaning tank 309. The float 320 squeezes the cleaning agent inside the cleaning tank 309. The cleaning agent is transferred to the first nozzle 311 and the second nozzle 312 through the third pipe 310. The first nozzle 311 and the second nozzle 312 transfer the cleaning agent to the three-phase separator 1.

[0065] If the mixed-transport skid device is installed outdoors, the construction personnel open valve 319 on the feed pipe on one side of the corrosion-resistant box 314 to add corrosion inhibitor to the corrosion-resistant box 314. Then, when the exhaust hot air is discharged and another part is introduced into the storage box 301, the air pressure pushes the push plate 302 to move inside the box. At the same time, the push plate 302 pushes the push rod 315 to move inside the corrosion-resistant box 314. The push rod 315, through the connecting rod, drives the block 316 away from the connection between the fifth pipe 317 and the corrosion-resistant box 314, and the corrosion inhibitor inside the corrosion-resistant box 314... The agent is transported through the fifth pipe 317 to the cleaning tank 309, where it mixes with the cleaning agent inside. Then, along with the cleaning agent, it is transported through the third pipe 310 to the first nozzle 311 and the second nozzle 312. Then, the construction personnel open the valve 319 on the fourth pipe 313, and a portion of the corrosion inhibitor is transported along with the cleaning agent through the second nozzle 312 to the fourth pipe 313. The fourth pipe 313 is then sprayed onto the outer surface of the three-phase separator 1 through a nozzle at one end.
