摘　　要：为评价小眼井的规模经济效益,1998年在朝阳沟薄荷台油田进行42口φ178mm小眼井的区域推广性试验,该油田上部地层胶结疏松,下部青一段至泉四段地层微裂缝发育,易发生井塌、井漏。对原来小眼井钻井液进行了改进,经36口小眼井使用表明,改进后的小眼井钻井液封堵性及润滑性能好,防卡、防塌能力强,解决了该油田井漏、井塌的问题,与小眼井钻井工艺配合,提高了机械钻速,缩短了钻井周期,使小眼井钻井综合成本降低了11.7％。Hole collapses and lost circulations are frequently encountered during drilling in Bohetai Block of Daqing Oilfield. Slim hole drilling in the block is especially difficult, pipe stucks and lost circulations are the potential risks due to its small annular and high flow friction. A drilling fluid system for slim hole drilling in this area is developed, field using was successful.
