摘　　要：针对中原油田文101区块地层压力系数不可靠、砂岩地层掉块、出水和井漏等问题,优选抗盐两性离子磺酸盐聚合物CPS-2000、聚合铝防塌剂AOP-1、防塌润滑剂JHF-2等处理剂配制成了聚合物钻井液。该钻井液性能稳定、抑制性强和润滑性好,且防塌效果明显,满足开窗侧钻小井眼钻井的需求。在文101-侧17井、文101-侧49井和文284侧井的施工过程中,井壁稳定,井径规则,井径扩大率小,电测和下套管均一次性成功。In order to deal with downhole problems encountered in block Wen101 Zhongyuan oil field,such as unreliable formation pressure factor,sloughing,water invasion and mud loss,a polymer drilling fluid system is optimized with agents of amphion sulphonate polymer CPS-2000,anti-sloughing agentAOP-1 and lubricator JHF-2.This drilling fluid system is applied successfully in wells of Wen101-17,Wen101-49 and Wen284,which ensures the wells having advantages of stable wellbore,small borehole diameter enlargement ratio and high success ratio of running casing and logging.
