摘　　要：滨4-10-10井是胜利油田滨4区块平方王油田的一口生产井,钻探目的是开发平方王油田东块沙四中部油藏,完钻层位沙四段。滨4区块地层联通性好,孔隙度大,并不同程度存在着大孔道及地层亏空,漏失严重。研制开发出了新型随钻堵漏钻井液,并在滨4-10-10井进行现场试验,取得了良好的防漏和堵漏效果,实现了边钻进边防漏边堵漏的综合堵漏措施,达到了快速安全钻进的目的。现场使用表明,随钻堵漏钻井液性能稳定,能够快速提高粘度和切力,性能易于现场调整,具有很强的防塌润滑性及一定的安全性,同时又具有堵漏作用,起到桥堵加固作用,与其它添加剂配伍性能好;具有一定的密度调节范围,不需要特殊设备,易于操作,施工简单,该钻井液体系具有很强的防漏、堵漏能力,具有常规钻井液的优良特性和很强的封堵能力及承压能力。Bin 4-10-10 well was a commercial well in Bin 4 block of Shengli oilfield.It was drilled to open up middle reservoir in Sha 4 block located on the east of Pingfangwang oilfield.The target formation was Sha IV.Bin 4 block had better connectivity and high porosity.The high capacity channel and formation were voided at a certain extent and leakage was seriously.The novel sealing fluid while drilling was developed and the field trial was conducted in the well of Bin 4-10-10.The effects of leak protection and se...
