摘　　要： 渤中地区沙河街地层微裂缝非常发育,地层易坍塌,井壁稳定周期短。笔者通过研究新型无固相储层强抑制钻井液体系,降低其水活度,提高其抑制性和封堵性,增强井壁稳定周期;选用具有单向液体开关性能的暂堵剂,加强储层保护。 The formation of Shahejie in Bozhong area is very developed,the formation is easy to collapse,and the period of wellbore stability is short.By studying a new type of drilling fluid system with strong inhibition of solid-free reservoir,the author reduces its water activity,improves its inhibition and plugging,and enhances the period of wellbore stability;selects temporary plugging agent with one-way liquid switching performance to strengthen reservoir protection.
