All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-8 of the specification, a three-phase separation skid-mounted pressurizing device for crude oil, gas and water comprises a base, wherein a tank body 1 is arranged on the base, one end of the tank body 1 is provided with an inlet 11, the top of the inner side of the tank body 1 is fixedly provided with a baffle 15, the baffle 15 is arranged opposite to the inlet 11, a mixture of oil, gas and water enters the tank body 1 from the inlet 11 and impacts the baffle 15, and after flowing into the tank body 1, the mixture is separated into an oil phase, a gas phase and a water phase; the bottom of the tank body 1 is provided with an oil drain port 12 and a water drain port 13, the upper end of the tank body 1 is provided with an exhaust port 14, after the oil-gas-water mixture is separated, an oil phase is discharged from the oil drain port 12, a water phase is discharged from the water drain port 13, a gas phase is discharged from the exhaust port 14, and a delivery pump 9 is arranged at the position of the oil drain port 12 and is used for delivering the oil phase to an oil delivery pipeline after being pressed.

In the above technical solution, the second water outlet 31 may be disposed on a side wall of the buffer tank 3, or may be disposed at the bottom of the buffer tank 3, and should be as large as possible when disposed at the bottom, so as to reduce the flow rate of the mixture. During normal use, the bottom of the baffle 4 should be as close as possible to the level of the oil phase in the buffer tank 3, typically 5-10cm, to reduce the rate of flow of the mixture into the oil phase. The edge of the buffer plate 4 is provided with a tapered surface from which the mixture flows down along the inner wall of the buffer tank 3 after flowing toward the inner wall of the buffer tank 3.
In this embodiment, the implementation manner is specifically as follows: the mixture of oil, gas and water is conveyed from the inlet 11 to the inside of the tank body 1, when the mixture flows out from the inlet 11, the speed is high, the impact force is high, firstly, the mixture impacts the baffle 15 to reduce the speed, and a part of gas phase is separated, and the gas phase flows from the gas outlet 22 to the inside of the tank body 1 at the right side of the upper end of the collecting hopper 2. After the mixture is slowed down, it flows down from the first water outlet 21 to the inside of the buffer tank 3 along the collecting hopper 2 and impacts the buffer plate 4 to further slow down, at this time, the flow direction of the mixture is changed to be substantially horizontal and spread around, and after passing through the position of the gap 41, it can flow into the oil phase inside the buffer tank 3 along the inner wall of the buffer tank 3. Through the setting of buffer tank 3 and buffer board 4, the mixture of oil gas water is slowed down when making on the one hand impact buffer board 4, on the other hand the mixture can flow into the oil phase in the buffer tank 3 downwards along the lateral wall of buffer tank 3, and is less to the impact force of oil phase, makes the fluctuation of oil phase in the buffer tank 3 less, and because this fluctuation is located buffer tank 3 basically, so influence less to the oil phase in jar body 1 to the direct liquid of entering jar body 1 of mixture of oil gas water, can produce great wave, causes the oil-water interface unbalance, takes place the problem of disorder.
Referring to fig. 1-4 of the specification, the embodiment further provides a buffer assembly 5, specifically, the buffer assembly 5 includes an outer cylinder 51, the outer cylinder 51 is installed at the upper end of the tank body 1, a connecting shaft 52 is vertically movably installed in the outer cylinder 51, a swivel 53 is rotatably connected to the connecting shaft 52, a first spring 54 is sleeved on the connecting shaft 52, two ends of the first spring 54 are respectively pressed with the swivel 53 and the bottom of the inner side of the connecting shaft 52, and the bottom end of the connecting shaft 52 is fixedly connected with the middle of the buffer plate 4.
When the oil-gas-water mixture impacts the buffer plate 4, the first spring 54 may serve as a buffer, that is, a part of kinetic energy and potential energy of the mixture is converted into kinetic energy of the buffer plate 4, the connecting shaft 52 and the swivel 53, and elastic potential energy of the first spring 54, so that the flow rate of the mixture can be further reduced.

It should be noted that, since the liquid level of the oil phase in the tank 1 is dynamically changed and the buffer plate 4 can move up and down, if the buffer plate 4 contacts with the oil phase in the buffer tank 3, a large fluctuation occurs, and therefore, the liquid level of the oil phase in the buffer tank 3 is detected by the liquid level sensor 6, when the liquid level of the oil phase is higher than a set value, the power assembly 7 needs to drive the buffer plate 4 to move up a distance to prevent the buffer plate 4 from contacting with the oil phase in the buffer tank 3, wherein the power assembly 7 can use a cylinder, and the power assembly 6 can also be installed at the bottom of the buffer plate 4.

Since the outer tube 51 is slidably mounted vertically to the tank 1 and the mixture is required to flow from the gap 41 to the inner wall of the buffer tank 3, the gap 41 has a small width, and when sand or stones are present in the mixture, the sand or stones remain at the edge of the buffer plate 4, and cannot be discharged, or cannot enter the bottom of the tank 1. The slag discharge assembly 8 is thus designed. When there are more sand and stones at the edge of the buffer plate 4, the amount of the mixture flowing downwards is reduced, so that more mixture is remained on the buffer plate 4, at this time, the pressure detected by the pressure sensor 80 is obviously increased, at this time, the buffer plate 4 can be driven to move upwards by the power assembly 7 and rotate the buffer plate 4, and when the buffer plate 4 moves upwards to the position of the slag hole 32, the sand and stones can be thrown out to the slag discharging assembly 8 for collection. Wherein, power pack 7 still includes the motor for drive buffer board 4 rotation.
