摘　　要：勘探开发低压、常压裂缝性潜山油气藏以及能量枯竭油气藏时,若采用常规钻井液钻井,井漏频发,不仅影响施工进度,钻井液还会污染产层、堵塞油气孔道,导致产能不理想。因此,文章对低密度钻井液体系中的微泡沫钻井液体系的发展史和特点进行了分析,对今后钻遇低压裂缝性地层时如何合理优选钻井液体系提供了理论依据。In the exploration and development of low pressure and atmospheric pressure fractured buried hill reservoirs and energydepleted reservoirs,if conventional drilling fluid is used for drilling,well leakage will occur frequently,which will not only affect the construction progress,but also drilling fluids can pollute the formation and block the oil and gas hole,resulting in unsatisfactory productivity.Therefore,this paper analyzes the development history and characteristics of the micro-bubble drilling fluid system in the low-density drilling fluid system,which provides a theoretical basis for the rational selection of drilling fluid system when drilling into low-pressure fractured formation in the future.
