Embodiment Construction
[0028] The present invention will be further described below in conjunction with accompanying drawing.
[0029] 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 first pneumatic control circuit 2 , a first actuator 3 , a second pneumatic control circuit 20 and a second actuator 30 . In the embodiment of the present application, the first cementing tool may be a rubber plug, and the second cementing tool may be a sphere. Wherein, the first pneumatic control circuit 2 is mainly used for injecting rubber plugs to complete the cementing operation. The second pneumatic control circuit 20 is mainly used to throw the ball to complete the cementing operation.
[0030] In the embodiment of the present application, the operating console 1 is the first intake start valve 4, the firs...

The invention relates to a pneumatic control system used for controlling cementing tools remotely. The pneumatic control system comprises a console, a first pneumatic control loop, a first actuating mechanism, a second pneumatic control loop and a second actuating mechanism, wherein the first pneumatic control loop is connected with the console; the first actuating mechanism communicates with the first pneumatic control loop; the first actuating mechanism is controlled by the first pneumatic control loop to stretch out, and thus release of the cementing tool is completed; the second pneumatic control loop is connected with the first pneumatic control loop in parallel; the second actuating mechanism communicates with the second pneumatic control loop; and the second actuating mechanism is controlled by the second pneumatic control loop to stretch out, and thus release of the second cementing tool is completed. The pneumatic control system has the advantages that the cementing tools are automatically controlled to conduct cementing work, the accuracy is high, the cementing efficiency is high, the safety of cementing work is improved, the risks of cementing construction are reduced, and the operability of remote control over the cementing tools 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...
