胜利松软地层密闭取芯技术在吉1井的应用

The Application of Sealed Coring Technology in Unconsolidated Formation in the Jixiang Well 1of the Shengli Oilfield

介绍了胜利油田Rmb-8100密闭取芯工具及工艺技术在吉1井的现场应用情况。在吉1井的取芯过程中,通过采取一系列技术措施,选择合适的密闭取芯工具、取芯钻头,采用油基密闭液,优化钻井参数,在白垩系银根组砂岩中密闭取芯进尺91.08m,芯长84.57m,收获率92.9%,密闭率97.8%,创造了吉祥油田浅层松软地层密闭取芯最好成绩。

The paper presents the field application and technology of Rmb-8100 sealed coring tool in the well 1 of Jixiang oilfield. In the coring operation in the cretaceous Yingen formation of the well 1, by taking some technical measures, selecting appropriate coring tools, appropriate coring bits, using oil base sealing fluid, we have completed coring footage 91.08m, the length of core 84. 57m ,coring recovery 92. 9% , core sealing rate 97. 8%, which created best achievement of unconsolidated formation sealed co- ring of J ixiang oilfield.
