Study On Monitoring And Control Algorithm Of Drilling

At present, in the course of drilling, many cases still rely on manual by experienced drilling personnel control. Since the operation for a long time, the operator's spirit and physical will be exertion, the inevitable happened of drilling stay and drilling accident, it will bright about problems of insecurity, and the volume control to the interruption is carried out, sending the quality of drilling varies are different from person, This will affect the quality of drilling, hole deviation and prone to sticking accidents.Facing these problems, the study of intelligent fuzzy automatic control technology and its delivery system of drilling to improve the drilling in promoting automation, reduce the cost of drilling, the quality of a certain theoretical and practical guide. In this paper, the characteristics of the work of drilling, completion of the design based on fuzzy control of the computer Constant pressure control drilling program, which used dual-loop control structure of the road, within the speed encoder feedback signals constitute a partial negative feedback loop, the drill will be external pressure measurement Feedback signals constitute another way of negative feedback loop, For the actual system is difficult to be precise mathematical model of the problem, we ring in the control algorithms using fuzzy control thought, broke through the limitations of conventional PID control. And Visual C++ programming environment designed and implemented a set of practical monitoring and control software. Its features include drilling Constant pressure control algorithms, underground signal read and display, filtering, encoding/decoding, the signal explained that a variety of parameters such as the display...
