Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0026] In the following detailed description, reference may be made to the various specification drawings that form a part of this application and that illustrate specific embodiments of the application. In the drawings, like reference numerals generally describe substantially similar components in different figures. The various specific embodiments of the present application have been described in sufficient detail below to enable those of ordinary skill in the relevant art and technology to implement the technical solutions of the present application. It should be understood that other embodiments may also be utilized or structural, logical or electrical changes may be made to the embodiments of the present application.

[0027] An embodiment of the present application provides a vehicle-mounted metering skid, which includes: a first gas-liquid separator, a second gas-liquid separator, a gas flowmeter, a liquid flowmeter, a first water cut monitor, a liquid pipeline, a gas pipeline, an inlet liquid elbow, and a mixed liquid outlet; wherein, the inlet of the inlet liquid pipe is used to receive the mixed liquid to be detected, the first gas-liquid separator and the second gas-liquid separator are arranged side by side vertically, the inlet liquid pipe includes an inlet liquid elbow and an inlet liquid straight pipe, the inlet liquid elbow has a preset bending angle and is communicated with the lower port of the inlet liquid straight pipe, the inlet liquid straight pipe and the first gas-liquid separator are arranged side by side vertically, an outlet is opened on the side of the inlet liquid straight pipe close to the first gas-liquid separator, and the outlet is communicated with the inlet of the first gas-liquid separator; the liquid outlet of the first gas-liquid separator is connected to the inlet of the second gas-liquid separator through a liquid pipeline, the liquid outlet of the second gas-liquid separator is connected to the inlet of the liquid flowmeter through a liquid pipeline, the liquid outlet of the liquid flowmeter is connected to the mixed liquid outlet through an outlet liquid pipeline, the first water cut monitor is arranged on the liquid pipeline between the liquid outlet of the second gas-liquid separator and the inlet of the liquid flowmeter for measuring the water cut of the liquid in the liquid pipeline; the gas outlet of the first gas-liquid separator is connected to the gas outlet of the second gas-liquid separator through a gas pipeline, and the gas outlet of the second gas-liquid separator is connected to the outlet liquid pipeline through a gas pipeline; the gas flowmeter is arranged on the gas pipeline between the gas outlet of the second gas-liquid separator and the outlet liquid pipeline.

[0028] The vehicle-mounted metering skid provided by the embodiment of the present application reduces the volume of the vehicle-mounted metering skid by arranging the gas-liquid separator and the inlet liquid pipe side by side, and optimizing the installation positions of the gas pipeline, the liquid pipeline and the first water cut monitor. Moreover, the vehicle-mounted metering skid provided by the present application has fewer accessories, and can accurately measure the gas volume, water volume and oil volume in the three-phase mixed liquid with one mixed liquid inlet. Overall, the structure is simple and compact, the transportation is stable, and the measurement efficiency of the oil well liquid volume can be significantly improved.

[0029] In some embodiments of the present application, optionally, the upper port of the inlet liquid straight pipe is a flange port, a flange blind plate is arranged on the flange port, and the flange port is used to arrange a water cut monitor.

[0030] In the embodiment of the present application, the first water cut monitor can be arranged at the upper port of the inlet liquid straight pipe, and the first water cut monitor can be used to directly measure the water cut of the mixed liquid entering the inlet of the inlet liquid pipe.

[0031] In some embodiments of the present application, optionally, the outlet of the liquid inlet pipe is connected to the liquid inlet of the first gas-liquid separator through a conveying pipeline, wherein the conveying pipeline includes a first conveying pipeline and a second conveying pipeline arranged side by side, the first conveying pipeline is used for conveying gas in the mixed liquid, and the second conveying pipeline is used for conveying liquid in the mixed liquid.

[0032] In the embodiments of the present application, the mixed liquid entering the liquid inlet pipe includes gas and liquid. Since the liquid inlet pipe includes a liquid inlet elbow and a liquid inlet straight pipe, the mixed liquid will impact the inner wall of the liquid inlet straight pipe multiple times after entering the liquid inlet straight pipe. In this way, part of the gas will escape from the mixed liquid, and the escaped gas will rise and then enter the first gas-liquid separator through the first conveying pipeline, while the liquid will flow into the first gas-liquid separator through the second conveying pipeline due to its large density. Arranging two conveying pipelines side by side up and down between the first gas-liquid separator and the liquid inlet pipe can separate gas and liquid in advance before the mixed liquid enters the first gas-liquid separator, thereby improving the separation efficiency of the first gas-liquid separator.

[0033] In some embodiments of the present application, optionally, the outlet of the liquid inlet pipe is connected to the liquid inlet of the first gas-liquid separator through a conveying pipeline, wherein the conveying pipeline includes a first conveying pipeline and a second conveying pipeline arranged side by side, and both the first conveying pipeline and the second conveying pipeline are used for conveying the mixed liquid.

[0034] During use, considering the flow rate of the mixed liquid, the separation of the mixed liquid in the liquid inlet straight pipe may not be complete, so that the mixed liquid containing liquid and gas can flow into both the first conveying pipeline and the second conveying pipeline.

[0035] In some embodiments of the present application, optionally, the vehicle-mounted metering skid further includes a skid-mounted frame for accommodating the liquid inlet pipe, the first gas-liquid separator, the second gas-liquid separator, the gas flowmeter, the liquid flowmeter, and the first water cut monitor; wherein the skid-mounted frame includes a base and a top layer, and a plurality of first-type fixing brackets are arranged on the base in the direction towards the top layer, and the first-type fixing brackets are connected to the liquid pipeline for fixedly supporting the liquid pipeline; a plurality of second-type fixing brackets are arranged on the top layer in the direction towards the base, and the second-type fixing brackets are connected to the gas pipeline for fixedly supporting the gas pipeline.

[0036] In the embodiments of the present application, the vehicle-mounted metering skid has a skid-mounted frame made of metal material, which can play a role in fixing and supporting the liquid pipeline and the gas pipeline. In addition, the skid-mounted frame can be used to fix the liquid inlet pipe, the first gas-liquid separator, the second gas-liquid separator, the gas flowmeter, the liquid flowmeter, and the first water cut monitor on the truck. In this way, by moving the truck loaded with the vehicle-mounted metering skid, the measurement of the oil liquid of different oil wells can be carried out efficiently.

[0037] In some embodiments of the present application, optionally, the first gas-liquid separator and / or the second gas-liquid separator is a cyclone gas-liquid separator. The cyclone gas-liquid separator includes a cyclone separation cylinder and a gas outlet assembly.

A float and a plug are respectively arranged at both ends of the float link.

[0038] In the embodiments of the present application, the gas-liquid separator is a cyclone separator. A float is included in the gas outlet assembly at the upper part of the cyclone separator. If there is liquid flowing upward and ready to flow out from the upper gas outlet end, the float will float upward under the action of the liquid, so that the gas outlet is blocked. At this time, neither gas nor liquid can flow out from the gas outlet, thus achieving the effect of restricting the liquid from flowing out from the gas outlet.

[0039] In some embodiments of the present application, optionally, the gas outlet assembly includes a first flange, a second flange and a collector connected in sequence, and the internal cavities of the three form the movable chamber; among them, the collector is a U-shaped structure. The port of the collector is connected to the second flange. A concave head is fixed on the collector. The concave head is provided with a through hole along its center line. The gas outlet is provided at the center of the arc end of the collector. The gas outlet and the through hole are communicated through the cavity of the collector. The through hole is communicated with the movable chamber; the float link is inserted into the movable chamber. The plug is a conical convex head. When the float floats up, the convex head on the float link enters the through hole of the concave head, so that the through hole is closed.

[0040] In some embodiments of the present application, the movable chamber is composed of the internal cavities of the first flange, the second flange and the collector. A conical convex head is arranged at the end of the float link. When the float moves upward, the convex head is inserted into the through hole of the concave head, so that the through hole in the gas outlet is closed, and the liquid cannot flow out from the gas outlet. The whole structure is simple and compact, and is convenient for assembly.

[0041] In some embodiments of the present application, optionally, the concave head is fixed to the collector through the fixing piece. The fixing piece is a circular structure. The fixing piece covers the port of the collector. The convex head is inserted into the middle area of the fixing piece.

[0042] The concave head can be fixed in the middle area of the collector by using a circular fixing piece, which can improve the fixing strength of the concave head.

[0043] In some embodiments of the present application, optionally, both the gas flowmeter and the liquid flowmeter are float flowmeters.

[0044] The float flowmeter can measure the flow rate of the mixed liquid, has low requirements for the physical properties of the fluid to be measured, can accurately measure the flow rate, and has high reliability and stability, with a simple structure and convenient operation.

[0045] In some embodiments of the present application, optionally, the heights of both the first gas-liquid separator and the second gas-liquid separator are less than 1.6 m.

[0046] The height of the vehicle-mounted metering skid proposed in the embodiments of the present application is less than 1.6 m, which is convenient for transportation when loaded on a vehicle and has high transportation stability.
