Abstract

The invention provides an electric fracturing switch wireless electric control system comprising a master controller, a motor driving module, a motor round number detecting circuit module, and a computer. The motor round number detecting circuit module is connected with the master controller and detects the number of rotated rounds of a motor shaft. The master controller is connected with the motor driving module, receives instructions transmitted by the computer, and controls the motor driving module according to the instructions transmitted by the computer and the number of rotated rounds of the motor shaft. The motor driving module is connected with an external motor and drives the external motor to perform forward rotation, backward rotation, and stop operation under the control of the master controller, thereby controlling an electric fracturing switch to switch among an on position, an off position, and a middle position. The electric fracturing switch wireless electric control system solves problems of high operating ambient temperature and high pressure of an electric fracturing switch wireless communication part.

Description

technical field [0001] The invention relates to the technical field of oilfield well completion, in particular to a radio control system for electronically controlled fracturing switches in the oilfield repeated switch multi-stage segmented well completion technology. Background technique [0002] As the oilfield enters the late stage of development, the development objects are becoming more and more complex, and the development difficulty is becoming more and more difficult. Interlayer contradictions and intralayer differences in major oilfields are becoming more and more prominent, and the grades of newly added resources are getting lower and lower. Horizontal wells can increase the contact area between the wellbore and the oil layer, and increase oil and gas production and ultimate recovery. However, with the extension of oil exploration and development time, conventional oil fields such as medium and high permeability gradually decrease, and unconventional gas reservoirs...
