Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] see figure 1 , which is a schematic diagram of the pneumatic control system of the present invention for remotely controlling the pneumatic control system of the cementing tool. As shown in the figure, the pneumatic control system includes a console 1 , a pneumatic control circuit 2 and an actuator 3 . In the embodiment of the present application, the cementing tool may be a rubber plug.

[0021] In the embodiment of the present application, the operating console 1 is the intake start valve 4, the reset start valve 231, the reset control valve 232, the intake control valve 5, the first stroke valve 6 and the second stroke valve 7 as described below An installation panel (not shown in the figure) is provided to complete the installation and fixing of the above valve components. Further, the above-mentioned valve components can complete their respective functions ac...

Abstract

The invention relates to a pneumatic control system for remote control over a well cementing tool. The pneumatic control system comprises an operating desk, a pneumatic control loop connected with the operating desk, and an executing mechanism communicated with the pneumatic control loop, wherein the pneumatic control loop controls the executing mechanism to stretch out to complete release of the well cementing tool. The pneumatic control system has the advantages that the accuracy of automatically controlling the well cementing tool to carry out well cementing work is high, the well cementing efficiency is high, the labor intensity of operating personnel is relieved, the safety of well cementing work is improved, the risk of well cementing construction is lowered, and the operability of remote control over the well cementing tool is improved.

Description

technical field [0001] The invention relates to the technical field of petroleum cementing equipment, in particular to a pneumatic control system for remotely controlling cementing tools. Background technique [0002] The cementing tool can complete cementing operations such as circulation, slurry replacement, ball throwing and rubber plug release. In the cementing construction project, it is necessary for the construction personnel to manually complete the opening and closing of the stop pin or manually complete the pitching etc. at close range. [0003] After years of development, the structure and function of cementing tools have gradually improved. However, with the continuous development of drilling technology from shallow wells to medium-deep wells, deep wells and ultra-deep wells, exploration and development have gradually entered the depths of the ocean or the hinterland of deserts. . Like this, just make the cementing pipe string in the cementing operation process...
