摘 要:在充分分析中拐凸起邻井地质资料和实钻情况后,针对井下可能出现的复杂情况,制定预防措施,优化井身结构,优选钻头,强化工程技术措施,优化钻井液体系,细化钻井液措施,3500m左右的探井实现了二开安全顺利完井,钻井周期缩短45.28%,平均机械钻速提高47.58%,复杂时率降低为零,井径规则,电测一次成功率100%,提速增效成果显著。After complete analysis of geology materials of convex adjacent wells and the in-situ drilling condition in Zhongguai oil field,we optimized the casing program,optimally selected bits,improved technical measures,optimized the drilling fluid system and subdivided the drilling fluid measures to realize smooth completion in the second spudding for a 3500 m of exploitation well.The average drilling period was shorten by 45.28%;theaverage ROP of 47.58% was increased;the complexing time rate was decreased to zero;the well diameter was formal;the successful rate of electric logging in one time was 100%,and the speed increase and efficiency are significant.
