A fractured wellhead

Abstract

The invention discloses a fracturing wellhead, which comprises a main body, a first fracturing valve is arranged on the top of the main body, a connecting flange is installed on the bottom of the first fracturing valve, and a connecting flange is installed on the bottom of the connecting flange. A fracturing head, wherein the bottom of the fracturing head is provided with a second fracturing valve, the bottom of the second fracturing valve is provided with a third fracturing valve, and the connection between the fracturing head and the second fracturing valve is Between the fracturing head and the third fracturing valve, connecting flanges are installed, and the front parts of the first fracturing valve, the second fracturing valve and the third fracturing valve are fixed with connecting arms. In the present invention, by setting the installation sleeve, when the installation sleeve is installed on the outside of the disk-shaped handle, the worm is rotated, and the worm drives the disk-shaped handle to rotate through the meshing structure formed with the gear outside the installation sleeve. Control the radian of the disc handle to adjust the opening and closing degree of the valve, which is convenient to use.

Description

technical field [0001] The invention relates to the technical field of fracturing wellheads, in particular to a fracturing wellhead. Background technique [0002] In the field of petroleum, fracturing refers to a method of using hydraulic action to form cracks in oil and gas layers during the process of oil or gas production, also known as hydraulic fracturing. The flow environment can increase the production of oil wells, which can play an important role in improving the flow conditions at the bottom of the oil well, slowing down the interlayer and improving the production status of the oil layer. [0003] Although there are many types and quantities of the current fracturing wellheads, there are still certain problems in the existing fracturing wellheads, which bring certain inconvenience to the use of the fracturing wellheads. [0004] However, during the use of most fracturing wellheads, most of them control the opening and closing of the valve by turning the disc-shape...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a fracturing wellhead, which solves the problem that during the use of the fracturing wellhead, the opening and closing of the valve is mostly controlled by rotating the disc-shaped handle, and it is difficult to accurately control the arc of the disc-shaped handle to adjust the valve. The degree of opening and closing is adjusted, which affects the use of the problem
