Description

Technical Field

[0001] The present invention relates to the technical field of shale oil and gas exploitation, and in particular to a hand-liquid-operated integrated intelligent control fracturing valve. Background Art

[0002] With the economic growth and the increasing demand for energy, the demand for shale oil and gas is increasing. However, with the continuous improvement of fracturing technology, the demand for fracturing equipment is also increasing. With the exploitation of shale oil and gas, fracturing equipment is required to be more intelligent and efficient, which will inevitably lead to the replacement of traditional equipment. New equipment needs to meet the challenges of high temperature resistance, high pressure resistance, high sulfur content and other harsh working conditions brought by new working conditions. The hand-liquid-operated integrated intelligent control fracturing valve is an important component of fracturing equipment and is particularly important.

[0003] For example, a fracturing valve with application number CN202122832840.2 and authorization announcement date 20220628, the fracturing valve comprises: a valve body, having a fluid channel; a valve stem assembly, movably arranged in the valve body, the valve stem assembly comprising a valve stem and a valve plate arranged on the valve stem, the valve plate being used to control the opening and closing state of the fluid channel; a driving device; a transmission structure connected to the valve stem; a connecting structure, the connecting structure respectively cooperates with the output end of the driving device and the transmission structure to stop rotation, so as to connect the driving device and the transmission structure through the connecting structure; wherein the driving device drives the connecting structure to rotate, so as to drive the transmission structure to move through the connecting structure, so that the valve stem moves along its extension direction. The utility model effectively solves the problem that it is difficult for staff to operate the fracturing valve in the prior art.

[0004] At present, traditional fracturing valves are controlled manually or hydraulically. In the fracturing service process, two fracturing valves are generally used in series. The manual valve is operated manually, and the hydraulic valve is operated by a remote hydraulic control station. However, whether it is a manual or hydraulic gate valve, there are the following disadvantages in its working process:

[0005] 1. During the operation of the manual valve, the valve is judged by counting the number of turns and observing the position. After it is in place, it is rotated 1 / 4 turn to determine the fully open position of the valve. However, during the on-site service process, sand often enters the middle cavity, making the number of turns inaccurate and unable to judge whether the valve is in place;

[0006] 2. The hydraulic valve can only be opened and closed by the remote hydraulic drive device. It can only be observed from a close distance whether the valve is opened and closed. After the sand enters the middle cavity, it is difficult to judge whether the valve is opened and closed.

[0007] 3. Under each working condition, a manual valve and a hydraulic valve are connected in series. Usually, they are operated manually. When the hydraulic valve fails, the manual valve is operated manually, which increases costs and is unsafe.

[0008] 4. Whether sand has entered the valve cavity is also determined by the process and is difficult to determine intelligently. Summary of the invention
