Title: Innovations of Chunguo Yang in Automatic Control Systems
Introduction
Chunguo Yang is a notable inventor based in Dezhou, China. He has made significant contributions to the field of automatic control systems, particularly in the context of underbalanced drilling. His innovative approach has led to the development of a unique patent that addresses critical challenges in drilling operations.
Latest Patents
Chunguo Yang holds a patent for an "Automatic control system and method for bottom hole pressure in the underbalance drilling." This invention provides an automatic control system and method for bottom hole pressure (BHP) in underbalanced drilling. It relates to computer automatic control technology. The automatic control system includes a processing module for the BHP based on the mechanisms of hydraulics. The BHP in underbalanced drilling is calculated from the acquired standpipe pressure (SPP), the calculated circulating pressure loss in the drilling tools, drill bit pressure drop, and the fluid column pressure in the drill string. The resulting BHP is then compared with the set pressure value of the system. If the BHP is higher or lower than the set pressure, an instruction to regulate throttle valve opening is issued to bring the BHP back to the set pressure range, completing BHP monitoring and control. Chunguo Yang has 1 patent to his name.
