针对中原油田勘探开发过程中易坍塌、漏失的复杂井段 ,提出用“安全窗口”新观念来分析其受力状态 ,以利于研究安全生产的有效措施。依据MMH防塌防漏机理 ,借助OFI - 170 - 5 0高温高压动失水仪、改型API堵漏仪等仪器 ,分析了MMH钻井液体系的防塌防漏效果 ,为现场安全生产提供了一定的理论根据。
Aiming at the complex well sections prone to collapsing and losing during the exploration and development of Zhongyuan Oilfield, a new concept of “safety window” is proposed to analyze the stress state in order to facilitate effective research on safety production. According to MMH collapsible and leakproof mechanism, with the help of OFI - 170 - 5 0 high temperature and high pressure moving water loss meter and modified API plugging leak meter, the effect of collapse prevention and leakage prevention of MMH drilling fluid system was analyzed and provided for on - site safety production A certain theoretical basis.
