中国石油网消息（特约记者吴玲瑶 通讯员张伟）12月7日，新疆顺北区块作业现场传来喜讯：由川庆钻探工程公司承担取芯作业的顺北84斜井在井深9055.66米成功完成取芯，创造国内取芯深度最新纪录。
顺北84斜井是中国石化西北局部署在新疆顺北区块的一口勘探井，设计完钻井深9232.49米。该井目的层埋藏深、压实性强，储层碳酸盐岩孔洞、裂缝发育，井斜甚至达到49度，不仅严重影响机械钻速及取芯单筒进尺和收获率，还同时存在井漏、溢流等井控风险。
为圆满完成本次任务，川庆钻探取芯技术团队按照“不造成井控问题、不造成井下复杂、确保取芯收获率”原则，采用自主研发的SPQ121-66定向井取芯工具和CQT558G金刚石取芯钻头，与中国石化胜利80116钻井队协同配合，历时3天时间，成功在该井井段9050.66米至9055.66米取芯1筒次、进尺5米、芯长4.9米、收获率达98%，为建设方精准评价储层提供了第一手地质资料。
