中原油田钻井二公司近年来,针对华北气田钻水平井段长、大位移和大斜度的难题,巩固和发展环保型保护储层钻井液技术,开展了钾铵基悬浮乳液体系技术尝试。通过该体系的实施,证明该体系具有优良的润滑、防塌、抗温和保护油气层性能,并有抑制性和抗污染能力。可以在华北地区大力推广。
In recent years, in order to consolidate and develop the environmentally friendly drilling fluid technology for reservoir protection, aiming at the problems of long, large displacement and large gradient of horizontal wells in North China Gas Field, a technological attempt of potash ammonium-based suspension emulsion system has been carried out. Through the implementation of the system, the system has proved that the system has excellent lubrication, anti-collapse, anti-moderate protection of the reservoir performance, and inhibitory and anti-pollution ability. Can be vigorously promoted in North China.
