摘　　要：目前适用于低压层钻进的钻井液技术有可循环微泡沫钻井液、可循环玻璃微珠钻井液、低密度油基钻井液等低密度钻井液以及精细控压钻井技术等。通过水平井低压油层施工的适应性分析,精细控压钻井技术较低密度钻井液体系在满足低压油层防漏、水平井施工以及环保方面具有明显优势。At present,the drilling fluid technologies suitable for low-pressure reservoir drilling are low-density drilling fluids such as Recyclable Micro Foam drilling fluid,Recyclable glass microbead drilling fluid,low-density oil-based drilling fluid,and managed pressure drilling(MPD) technology. Through the adaptability analysis of lowpressure oil reservoir drilling in horizontal wells,the managed pressure drilling(MPD) technology has obvious advantages in meeting the requirements of low-pressure reservoir leakage prevention,horizontal well drilling and environmental protection.
