Motor-driven fiber-avoidance accurate oriented perforating process

The fiber-avoidance perforating process of the novel fiber logging technology has the defects of large cumulative error, limited perforating gun length and easy centralizer/anchoring device sticking. In order to solve these problems, a new type of motor-driven fiber-avoidance accurate oriented perforating process was designed by means of ultrasonic underwater wireless communication method and inter-gun wireless cascade communication method. By virtue of this newly designed process, the physical models of intelligent telemetry device, gun head controlling device, inter-gun measuring and controlling device and surface system were developed. In addition, the corresponding performance test devices were developed to test the rotary driving force performance of motor and the performance of underwater wireless communication technology and experimentally study the application range of core chip. Multiple tests show that the program of the novel motor-driven oriented perforating process is feasible and provides a new idea for the related research on the omni bearing control technology for oil and gas wells and the development of new oriented perforating process series.
