[0002] Oil extraction refers to the extraction of oil resources from underground reservoirs by drilling and other means. In the process of oil extraction, it is necessary to measure the oil content in the underground reservoir in order to evaluate the oil reserves and determine the extraction plan. In oil extraction, gas-liquid separation equipment is widely used to measure the oil content in underground reservoirs.

DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0028] In the following detailed description, reference may be made to the various specification drawings that are part of the present application and are used to illustrate specific embodiments of the present application. In the accompanying drawings, similar reference numerals describe substantially similar components in different figures. The various specific embodiments of the present application are described below in sufficient detail so that a person of ordinary skill in the art with relevant knowledge and skills in the art can implement the technical solutions of the present application. It should be understood that other embodiments may also be used or structural, logical or electrical changes may be made to the embodiments of the present application.

[0029] The embodiment of the present application proposes a cyclone separator, including a float assembly, a cyclone separation cylinder and a gas outlet assembly, wherein the cyclone separation cylinder is a cylindrical structure with one end sealed and the other end open, and the side of the cyclone separation cylinder is provided with a liquid inlet and a liquid outlet; the gas outlet assembly includes a shell, a float assembly limiting structure and a gas outlet arranged on the top of the shell, the bottom of the shell is sealed and connected to the open end of the cyclone separation cylinder, the internal cavity of the shell is connected to the inner cavity of the cyclone separation cylinder, and the two form the activity space of the float assembly; the float assembly includes a float connecting rod and a gas outlet arranged respectively on the outer shell. The float and the plug at both ends of the float connecting rod; a float assembly limiting structure is provided on the inner wall of the shell, a ventilating structure is provided on the float assembly limiting structure, the float connecting rod is passed through the float assembly limiting structure, the plug is limited between the float assembly limiting structure and the gas outlet, and the float connecting rod and the float assembly limiting structure are movably connected; when in use, if the liquid in the mixed liquid entering the liquid inlet flows toward the gas outlet, the float, under the action of the buoyancy of the liquid, causes the plug on the float connecting rod to move toward the gas outlet to block the gas outlet.

[0030] The cyclone separator proposed in the embodiment of the present application is provided with a movable float. When the liquid in the mixed liquid flows to the gas outlet, the float floats, so that the plug connected to the float blocks the gas outlet, preventing the liquid from flowing out of the gas outlet, thereby improving the separation purity of gas-liquid separation. The cyclone separator of the present application is often used in the process of measuring the gas and oil content in the petroleum mixed liquid. After the mixed liquid obtained from the oil well is separated by the cyclone separator, the content of the separated gas is measured by a gas flow measurement device, and the water content of the separated liquid and the flow rate of the liquid are measured by a water content monitor and a liquid flow measurement device, so that the oil content in the liquid can be measured. Since the cyclone separator of the present application can prevent the liquid from entering the gas being separated, the measurement accuracy of the gas content can be improved. In addition, the cyclone separator proposed in the embodiment of the present application has a simple structure and is easy to produce.

[0031] In some embodiments of the present application, optionally, the outer shell includes a first flange, a second flange and a cap connected in sequence, the bottom of the first flange is connected to the open end of the cyclone separation cylinder, the cap is a shell structure, the gas outlet is opened on the top surface of the shell structure, and a sealing port is opened at the other end of the shell structure opposite to the top surface, and the sealing port abuts against the end surface of the second flange, and the central cavity of the first flange, the central cavity of the second flange and the inner cavity of the cap are connected to form an internal cavity of the outer shell.

[0032] In the present application, the housing is formed by connecting a first flange, a second flange and a cap. The first flange and the second flange have simple structures. A plurality of connecting through holes are arranged along the circumference of the first flange and the second flange. The first flange and the second flange can be connected and fixed by fasteners. The cap has a sealing port and a gas outlet at both ends, and one end with the sealing port is connected to the second flange. Using the common first flange and the second flange as part of the housing can not only improve the installation efficiency, but also reduce the manufacturing cost.

[0033] In some embodiments of the present application, optionally, the float assembly limiting structure is a long strip structure, and the air permeable structure is an air permeable groove opened along the thickness direction of the float assembly limiting structure; or, the float assembly limiting structure is a circular sheet structure, and the air permeable structure is an air permeable hole opened along the axial direction of the float assembly limiting structure; or, the float assembly limiting structure is a polygonal sheet structure, and the air permeable structure is an air permeable groove opened along the thickness direction of the float assembly limiting structure.

[0034] In the embodiment of the present application, the float assembly limiting structure is used to limit the position of the float assembly, so that the float and the plug in the float assembly can be respectively located on both sides of the float assembly limiting structure, so that the float assembly can stand upright in the activity space of the float assembly and can move freely. When the liquid flows to the gas outlet, the float float moves toward the gas outlet and drives the plug to move, so that the plug blocks the gas outlet and prevents the liquid from flowing out of the gas outlet. The float assembly limiting structure has many forms, which can be long strips, discs, etc., and the present application does not make specific restrictions on this.

[0035] In some embodiments of the present application, optionally, the float assembly limiting structure is an annular sheet structure, the outer circumference of the sheet structure is fixed on the inner wall of the middle hole of the first flange, the float connecting rod is passed through the inner hole of the sheet structure, and the air-permeable structure is an air-permeable hole opened between the inner hole of the sheet structure and the outer circumference.

[0036] In an embodiment of the present application, the float assembly limiting structure is an annular sheet structure, the float connecting rod is inserted into the inner hole of the float limiting structure, and the float connecting rod can move in the inner hole toward the gas outlet or away from the gas outlet. The gas can reach the middle cavity of the second flange and the cavity of the cap through the air vent, and finally flow out from the gas outlet. In this embodiment, the float limiting structure is similar to an annular screen structure, and the outer circumference is fixed in the mounting groove on the inner wall of the first flange. In some embodiments, optionally, the float limiting structure also includes a boss, the boss is a hollow structure, and the hollow part in the boss is connected to the inner hole of the float limiting structure.

[0037] In some embodiments of the present application, optionally, the float assembly limiting structure further includes a righting sleeve, the righting sleeve is fixed in the inner hole, and the float connecting rod is inserted into the righting sleeve.

[0038] The stabilizing sleeve can limit the moving direction of the float connecting rod, so that the float connecting rod moves along the axial direction of the stabilizing sleeve. In this way, when the float moves, the plug can accurately block the gas outlet to prevent liquid from flowing out of the gas outlet.

[0039] In some embodiments of the present application, optionally, the cap includes a connected collector and a fixing tube, the cross-section of the collector along the center line is U-shaped, the arc-shaped end surface of the collector is the top surface of the cap, and the fixing tube is used to connect and fix the second flange and the collector.

[0040] In the present application, the collector is U-shaped to better collect gas, so that the gas flowing to the gas outlet is collected and then flows out of the gas outlet quickly. In addition, the fixed pipe can be conveniently connected to the collector and the second flange.

[0041] In some embodiments of the present application, optionally, the cap also includes a fixing plate and a recessed head, wherein the fixing plate is fixed on the inner wall of the fixed tube, and the recessed head is a hollow cylindrical structure, which is inserted on the fixing plate, and the gas separated from the mixed liquid passes through the hollow structure of the recessed head and the inner cavity of the collector and flows out of the cyclone separator from the gas outlet.

[0042] In the present application, the female head is fixed to the fixed tube via a fixing plate. During assembly, the fixing plate, female head and fixed tube can be assembled first, and then the fixed tube can be fixed between the collector and the second flange, which can improve installation efficiency.

[0043] In some embodiments of the present application, optionally, the fixing plate is a circular sheet structure, a boss is provided in the middle of the fixing plate toward the gas outlet, the inner diameter of the through hole in the boss is smaller than the inner diameter of the through hole on the main body of the fixing plate, the through hole in the boss is connected to the through hole on the main body of the fixing plate, and the recessed head is inserted into the through hole on the main body of the fixing plate.

[0044] In some embodiments of the present application, optionally, the recessed head is fixedly connected to the fixing plate via threads.

[0045] In some embodiments of the present application, optionally, the recessed head and the fixing plate are threadedly connected, and the inner diameter of the through hole in the boss is smaller than the inner diameter of the through hole on the body of the fixing plate, which can limit the depth of the recessed head inserted into the through hole, thereby facilitating connection and installation.

[0046] In some embodiments of the present application, optionally, the shape of the recessed head matches the shape of the plug, and when the plug enters the recessed head, the hollow structure in the recessed head is blocked.

[0047] In some embodiments of the present application, optionally, the recessed head is a conical columnar structure, and the plug is a conical structure.

[0048] The concave head is set as a conical columnar structure to better match the plug. Since the end of the concave head close to the plug is a conical opening, the probability of the plug moving toward the gas outlet and entering the concave head becomes greater. After entering the concave head, the cylindrical hollow structure of the concave head and the plug are more tightly fitted, further preventing the liquid from flowing out and improving the purity of the separated gas.

[0049] In some embodiments of the present application, optionally, the float includes a buoy cavity and a buoy cover, the buoy cover is detachably connected to the buoy cavity, the buoy cavity is a cylindrical structure with one end closed, and the float connecting rod and the buoy cover are detachably connected.

[0050] The cavity in the float can reduce the weight of the float, so that even if a small amount of liquid flows out in the direction of the gas outlet, the float can move under the action of the liquid, so that the plug blocks the gas outlet and improves the reaction sensitivity of the float. The float connecting rod and the upper cover of the float are detachably connected, and the float can be replaced when there is a problem with the float. In addition, in an embodiment of the present application, a circular groove opened along its axial direction is provided on the top of the plug, and the float connecting rod is a hollow rod, which can further reduce the weight of the float assembly and improve the sensitivity of the float to floating when it encounters liquid.
