Description

Technical Field

[0001] This utility model relates to the field of oil production enhancement equipment technology, and in particular to a ring-shaped high-pressure manifold. Background Technology

[0002] With the continuous discovery and exploitation of oil and natural gas, the scale and number of fracturing operations are also increasing. This places greater demands on the safety of engines containing flammable liquids and the power requirements of fracturing pumps on fracturing trucks. The pressure and displacement output to the high-pressure manifold are also increasing. Typically, high-pressure manifolds are straight pipes, resulting in significant flow resistance and energy loss of fracturing fluid, as well as substantial erosion and wear on the pipe walls. These unresolved issues have hindered oil and natural gas extraction. Therefore, to improve these conditions, we propose an annular high-pressure manifold. Utility Model Content

[0003] The purpose of this invention is to solve the problems in the prior art and provide a ring-shaped high-pressure manifold.

[0004] The technical solution of this utility model is:

[0005] A ring-shaped high-pressure manifold includes a high-pressure discharge assembly, which is disposed at both ends of a fracturing pump and forms a closed-loop annular pipeline with the fracturing pump.

[0006] To better form a closed loop and facilitate installation and disassembly, the high-pressure discharge assembly includes pipes and fittings. The pipes include four straight pipes, namely Straight Pipe I, Straight Pipe II, Straight Pipe III, and Straight Pipe IV. The fittings include L-type Fitting I, L-type Fitting II, T-type Tee I, and T-type Tee II. One end of L-type Fitting I and one end of T-type Tee II are respectively connected to the two ends of the fracturing pump. The other end of L-type Fitting I is connected to one end of Straight Pipe II. The other end of Straight Pipe II is connected to one end of T-type Tee I. The two ends of T-type Tee I are connected to one end of Straight Pipe I. The three ends of T-type Tee I are connected to one end of Straight Pipe III. The other end of Straight Pipe III is connected to one end of L-type Fitting II. The other end of L-type Fitting II is connected to one end of Straight Pipe IV. The other end of Straight Pipe IV is connected to the two ends of T-type Tee II.

[0007] To enhance safety, a protective component is also included. This component is located on the high-pressure discharge assembly side and includes a controllable plug valve and a water pipe. One end of the controllable plug valve is connected to the three ends of a T-type tee II, and the other end is connected to the water pipe, which can be used for fire extinguishing safety protection of the engine.

[0008] To achieve fire suppression and protection as quickly as possible, multiple nozzles are installed on the water pipes.

[0009] The present invention adopts the above structure and has the following advantages:

[0010] 1. The overall design uses a ring manifold to reduce the flow resistance of fracturing fluid in the fracturing pump and manifold. It has a buffer to reduce energy loss, make the pressure rise faster, balance the vibration caused by the internal stroke of the fracturing pump, and has a safety fire extinguishing function.

[0011] 2. It has a large output displacement, low flow resistance, and is equipped with protective components that can help extinguish engine fires safely. Attached Figure Description

[0014] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0015] like Figure 1 As shown, an annular high-pressure manifold includes a high-pressure discharge assembly and a protection assembly. The high-pressure discharge assembly is installed at both ends of the fracturing pump 12 and forms an annular closed loop with the fracturing pump 12.

[0016] like Figure 1 As shown, the high-pressure discharge assembly includes pipes and fittings. The pipes include four straight pipes, namely straight pipe I1, straight pipe II3, straight pipe III5, and straight pipe IV7. The fittings include L-type fitting I2, L-type fitting II6, T-type tee I4, and T-type tee II11. L-type fitting I2 has two ends, A and B. L-type fitting II6 has two ends, A and B. T-type tee I4 has three ends, A, B, and C. T-type tee II11 has three ends, A, B, and C. One end (A) of L-type fitting I2 and one end (A) of T-type tee II11 are respectively... Connected to both ends of fracturing pump 12, the other end (end B) of L-type connector I2 is connected to one end of straight pipe II3, the other end of straight pipe II3 is connected to one end (end B) of T-type tee I4, the two ends (end A) of T-type tee I4 are connected to one end of straight pipe I1, the other end of straight pipe I1 serves as the high-pressure outlet, the three ends (end C) of T-type tee I4 are connected to one end of straight pipe III5, the other end of straight pipe III5 is connected to one end (end A) of L-type connector II6, the other end (end B) of L-type connector II6 is connected to one end of straight pipe IV7, and the other end of straight pipe IV7 is connected to the two ends (end B) of T-type tee II11. Figure 1As shown, these pipes, joints and fracturing pump 12 form a closed-loop high-pressure manifold.

[0017] The protection assembly includes a controllable stopcock valve 10 and a water pipe 9. One end of the controllable stopcock valve 10 is connected to the three ends (C ends) of a T-type tee II 11, meaning the protection assembly is connected from the three ends (C ends) of the T-type tee II 11. The other end of the controllable stopcock valve 10 is connected to the water pipe 9, which is equipped with three nozzles, such as... Figure 1 As shown, D1, D2 and D3 are respectively. The water outlet of the three nozzles corresponds to the engine 8. The switch of the controllable plug valve 10 controls the fracturing fluid to be sprayed out through the water pipe 9 and the three nozzles to extinguish the fire and protect the engine 8.

[0018] Under normal circumstances, the controllable plug valve 10 is closed, and the high-pressure fracturing fluid pumped by the fracturing pump 12 is discharged from one end (end A) of the L-type connector I2 and one end (end A) of the T-type tee II11 on the left and right sides respectively. The fracturing fluid discharged from the left side flows through the L-type connector I2 and the straight pipe II3, and the fracturing fluid discharged from the right side flows through the T-type tee II11, the straight pipe IV7, the L-type connector II6 and the straight pipe III5. Then the two paths converge at the T-type tee I4 and are finally discharged from the straight pipe I1, which serves as the high-pressure outlet.

[0019] In an emergency, the controllable stopcock valve 10 can be opened, and the high-pressure fracturing fluid pumped by the fracturing pump 12 can also be sprayed out through the controllable stopcock valve 10, water pipe 9 and three nozzles to provide fire extinguishing and safety protection for the engine 8.

[0020] It should be noted that the engine 8, water pipe 9, controllable plug valve 10, fracturing pump 12, fracturing fluid, as well as pipes and joints mentioned above are all applications of existing technology.

[0021] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.

[0022] All equivalent changes and modifications made to the scope of this utility model patent application shall fall within the technical scope of this utility model.
