DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figure 1 As shown, an embodiment of the present invention provides an integrated separator device for oil fields, including: a tank body 1, a liquid inlet 11, a corrugated plate agglomerator 12, a gas phase separation tube 13, a cyclone separator 14, a sand phase separation chamber 151, a water phase separation chamber 161 and an oil phase separation chamber 171.

[0043] The liquid inlet 11 is arranged at the upper part of the tank body 1, the outer wall of the corrugated plate coalescer 12 is fixedly connected to the upper inner wall of the tank body 1 and is located below the liquid inlet 11, the lower outer wall of the gas phase separation tube 13 is fixedly connected to the inner wall of the corrugated plate coalescer 12, and a gas phase outlet 133 is arranged at the upper part through the upper part of the tank body 1, the outer wall of the cyclone separator 14 is fixedly connected to the middle inner wall of the tank body 1, and is located below the corrugated plate coalescer 12 and the gas phase separation tube 13.

[0044] The water phase separation chamber 161 is located inside the sand phase separation chamber 151, and the oil phase separation chamber 171 is located inside the water phase separation chamber 161. The bottom of the sand phase separation chamber 151, the bottom of the water phase separation chamber 161, and the bottom of the oil phase separation chamber 171 slope downward in sequence and are all fixedly connected to the lower inner wall of the tank body 1.

[0045] The bottom of the sand phase separation chamber 151 , the bottom of the water phase separation chamber 161 , and the bottom of the oil phase separation chamber 171 are successively lowered, and are respectively provided with a sand phase outlet 152 , a water phase outlet 162 , and an oil phase outlet 172 that transversely passes through the lower part of the tank body 1 .

[0046] In a possible embodiment, the crude oil enters the tank body 1 from the liquid inlet 11, and then undergoes agglomeration treatment through the corrugated plate agglomerator 12 to increase the particle size of the tiny oil droplets in the crude oil; the crude oil flows into the cyclone separator 14 from the lower side of the corrugated plate agglomerator 12, and in this process, the gas phase of the crude oil enters the gas phase separation pipe 13 and leaves the tank body 1 from the gas phase outlet 133. The crude oil from which the gas phase has been removed undergoes cyclone separation through the cyclone separator 14, and the separated sand phase, water phase, and oil phase enter the sand phase separation chamber 151, the water phase separation chamber 161, and the oil phase separation chamber 171, respectively, and leave the tank body 1 from the sand phase outlet 152, the water phase outlet 162, and the oil phase outlet 172, respectively.

[0047] like Figures 2 to 4 As shown, illustratively, the lower inner wall of the gas phase separation tube 13 is provided with an annular gas baffle 131 and a conical gas baffle 132 in sequence from top to bottom.

[0048] The outer side of the annular air baffle plate 131 is fixedly connected to the lower inner wall of the gas phase separation tube 13 , and the outer side of the conical air baffle plate 132 is fixedly connected to the lower inner wall of the gas phase separation tube 13 via a bracket.

[0049] The radius of the conical air baffle plate 132 is greater than the inner ring radius of the annular air baffle plate 131 , and smaller than the outer ring radius of the annular air baffle plate 131 .

[0050] Specifically, by arranging the annular air baffle 131 and the conical air baffle 132 in sequence from top to bottom, the oil-gas mixture can be prevented from directly and continuously passing through the middle of the inner ring of the annular air baffle 131, thereby increasing the complexity of the movement trajectory of the oil-gas mixture and improving the gas phase separation accuracy.

[0051] In this embodiment, two groups of annular air baffles 131 and conical air baffles 132 are provided.

[0052] Exemplarily, the annular air baffle 131 is a pleated structure that is inclined downward from the inner ring to the outer ring.

[0053] Specifically, through the pleated structure of the annular gas baffle 131 , the oil phase recovered from the oil-gas mixture can flow down from the pleated gaps, thereby leaving the gas phase separation tube 13 and entering the cyclone separator 14 .

[0054] Exemplarily, a filter membrane 1311 is fixedly disposed on the inner ring of the annular air baffle 131 .

[0055] Specifically, the filter membrane 1311 fixedly arranged on the inner ring of the annular air baffle 131 can filter the oil-gas mixture when it passes through the inner ring of the annular air baffle 131, thereby intercepting the oil phase in the oil-gas mixture. In this embodiment, the filter membrane 1311 is a nuclear pore membrane.

[0056] Exemplarily, the cyclone separator 14 includes: a cyclone support body 141 and a cyclone flow channel 142 .

[0057] The outer wall of the swirl flow channel 142 is fixedly connected to the inner wall of the middle part of the tank body 1 , and the inner wall is fixedly connected to the swirl support body 141 .

[0058] The swirl support body 141 is cylindrical in the middle, and the upper and lower parts are both protruding into cones.

[0059] Specifically, in this embodiment, the swirl flow channel 142 adopts a gradual single spiral flow channel, and the spacing between adjacent spirals gradually decreases, so that the effective flow area gradually decreases, generating a strong vortex, thereby making it easy to separate the sand phase, the water phase and the oil phase. The conical setting of the upper part of the swirl support body 141 makes it easier for the gas phase to gather on the longitudinal axis of the upper part of the tank body 1, and the conical setting of the lower part makes it easier for the oil phase to gather on the longitudinal axis of the lower part of the tank body 1.

[0060] Exemplarily, the tank body 1 is further provided with a first cleaning inlet 181 and a second cleaning inlet 184 .

[0061] The first cleaning inlet 181 is located above the corrugated plate coalescer 12 , and the second cleaning inlet 184 is located between the corrugated plate coalescer 12 and the cyclone separator 14 .

[0062] The first cleaning inlet 181 is located outside the tank body 1 and is provided with a first cleaning valve 183 . After the first cleaning inlet 181 enters the tank body 1 , a first nozzle 182 is also provided.

[0063] The second cleaning inlet 184 is located outside the tank body 1 and is provided with a second cleaning valve 186 . After the second cleaning inlet 186 enters the tank body 1 , a second nozzle 185 is also provided.

[0064] In a possible embodiment, the first cleaning valve 183 and the second cleaning valve 186 are opened at a fixed time during the separation process, and the first nozzle 182 and the second nozzle 185 clean the corrugated plate coalescer, the cyclone separator and the inner wall of the tank, so that the device can perform separation and cleaning operations at the same time. The mixed liquid produced by the cleaning can separate the sand phase, the water phase and the oil phase again during the separation process, ensuring the cleanliness without affecting the separation effect. In other possible embodiments, the cleaning process can also be performed after the separation is completed.

[0065] Exemplarily, the gas phase outlet 133 is connected to a gas phase flow meter 134 and a gas phase valve 135 in sequence.

[0066] The water phase outlet 163 is connected to a water phase flow meter 163 and a water phase valve 164 in sequence.

[0067] The oil phase outlet 172 is connected to an oil phase flow meter 173 and an oil phase valve 174 in sequence.

[0068] The gas phase flowmeter 134 , the gas phase valve 135 , the water phase flowmeter 163 , the water phase valve 164 , the oil phase flowmeter 173 , and the oil phase valve 174 are all electrically connected to the controller.

[0069] In a possible embodiment, the gas phase flow rate, water phase flow rate and oil phase flow rate are monitored respectively by the gas phase flow meter 134, the water phase flow meter 163 and the oil phase flow meter 173, and the gas phase flow rate, water phase flow rate and oil phase flow rate are regulated respectively by the gas phase valve 135, the water phase valve 164 and the oil phase valve 174.

[0070] Exemplarily, the water phase valve 164 is connected to the first cleaning valve 183 and the second cleaning valve 186 via a pipeline.

[0071] A circulating water pump 165 is further provided between the water phase valve 164 and the first cleaning valve 183 and the second cleaning valve 184 .

[0072] Specifically, by providing the circulating water pump 165 , the water phase flowing out of the water phase outlet 162 can be transported from the circulating water pump 165 to the first cleaning inlet 181 and the second cleaning inlet 184 , thereby realizing the recycling of water resources.

[0073] Exemplarily, the tank body 1 is also provided with a pressure sensor 191 and a liquid level sensor 192 .

[0074] The pressure sensor 191 and the liquid level sensor 192 are both electrically connected to the controller.

[0075] Specifically, the pressure in the tank body 1 is monitored by the pressure sensor 191, the liquid level in the tank body 1 is monitored by the liquid level sensor 192, and each valve in the device is regulated by the controller based on the pressure data and the liquid level data, so as to improve the safety of the separation process.

[0076] In a possible embodiment, the tank body 1 is further provided with a wall thickness sensor for monitoring the remaining service life and damage of the device.

[0077] Exemplarily, the liquid inlet 11 is also connected in sequence to a liquid inlet pipe 24 , a desanding cyclone 4 , a connecting pipe 22 , a desanding filter tank 3 , a raw liquid inlet pipe 21 and a raw liquid inlet 2 .

[0078] The connecting pipe 22 is provided with a liquid inlet pump 23 , and the liquid inlet pipe 24 is provided with a liquid inlet valve 25 .

[0079] In a possible embodiment, before the crude oil enters the tank body 1, it first passes through the raw liquid inlet 2, the raw liquid inlet pipe 21, the sand removal filter tank 3, the connecting pipe 22, the sand removal cyclone 4 and the liquid inlet pipe 24 in sequence, so that most of the sand phase can be filtered out in advance, thereby preventing blockage in the tank body 1 during separation.

[0080] The embodiment of the present invention improves separation efficiency and separation accuracy through the coordinated cooperation of a corrugated plate coalescer, a gas phase separation tube, a cyclone separator, a sand phase separation chamber, a water phase separation chamber and an oil phase separation chamber; the inner wall of the lower part of the proposed gas phase separation tube is provided with an annular gas baffle and a conical gas baffle in sequence from top to bottom, thereby increasing the complexity of the movement trajectory of the oil-gas mixture; the inner ring of the proposed annular gas baffle is fixedly provided with a filter membrane, thereby improving the gas phase separation accuracy; the proposed first cleaning inlet, the second cleaning inlet, the first nozzle and the second nozzle improve the cleaning convenience by cleaning the corrugated plate coalescer, the cyclone separator and the inner wall of the tank; the proposed gas phase flowmeter, the gas phase valve, the water phase flowmeter, the water phase valve, the oil phase flowmeter and the oil phase valve are all electrically connected to the controller, thereby improving the monitorability and controllability of the separation rate; a circulating water pump is also provided between the proposed water phase valve and the first cleaning valve and the second cleaning valve, thereby improving the utilization rate of water resources; the proposed pressure sensor and the liquid level sensor are all electrically connected to the controller, thereby improving the safety monitoring of the separation process.
