摘　　要：马平528井地层沉积为陆相古河道沉积,沉积岩以碎屑岩和泥岩为主,地层组成及岩性较为复杂,尤其是在该地层进行水平井施工,对钻井液体系及其各项性能参数提出了比常规水平井更高的要求。根据地层易坍塌、可钻性差、钻时慢、起下钻频繁、井眼浸泡时间长等特点,该井采用了强抑制性聚合醇润滑防塌钻井液体系,现场通过合理调整钻井液密度及其它性能参数,满足了水平井段的钻井施工要求。The Maping 528 Well is located on ancient river course of continental deposit which mainly consists of shale and clastic rocks. The formation and lithology are quite complicate. Therefore, drilling horizontal wells on such formation requires much more than conventional horizontal wells with respect to drilling fluid system and each property. Strong inhibitive drilling fluid is adopted according to sloughing formation, swelling fall off, bad drillabillity, low ROP, frequent trips, and long soak time, which performs strong inhibition, good anti sloughing, and lubrication. It meets drilling requirements for horizontal wells by adjusting density and other properties on site.
