Abstract: The degasser is at the forefront of gas logging and is fixedly installed on the buffer tank of drilling fluid outlet. It is one of the key equipments of gas logging operation. The degassing efficiency of degasser directly affects the stability, accuracy and continuity of gas logging data acquisition of mud logging, and then affects the discovery of the show of gas and oil and evaluation effect, and the safety of degasser directly affects the safety of operators. By analyzing the limitations of traditional degasser structure design, and referring to automatic control technology, magnetic induction technology and Archimedes buoyancy principle, a new engine degasser that meets international safe power supply, anti-blocking and adaptive liquid level was developed, which realizes automatic operation and safe power supply of degasser, reduces the labor intensity, eliminates potential risk, saves the maintenance cost, improves the stability, accuracy and continuity of gas logging data, and has better prospects for popularization and application.

Key words: gas logging, degasser, self-adaptation, safe power supply, automatic control, magnetic induction
