【摘要】：CQ-WOM油基钻井液是川庆钻探工程有限公司钴采工程技术研究院自主研发的无土相白油基钻井液体系。该体系在威202H3平台的应用情况表明,改进后的CQ-WOM油基钻井液性能稳定且易于调控,具有良好的抑制性、润滑性和储层保护特性,封堵性与滤失造壁性能优异,高温高压滤失量小于1 mL(120℃测定),可重复利用性强,完全满足钻井工程要求。为四川威远-长宁区块龙马溪储层水平井采用油基钻井液钻井提供了借鉴经验。
[Abstract]:CQ-WOM oil-base drilling fluid is a soilless white oil-based drilling fluid system developed by the Cobalt recovery Engineering Technology Research Institute of Chuanqing drilling Engineering Co Ltd. The improved CQ-WOM oil based drilling fluid is stable and easy to control, with good inhibition, lubricity and reservoir protection, excellent plugging and filtration wall building performance. The filtration loss at high temperature and high pressure is less than 1 mL(120 鈩，
