| 摘 要： | 伊拉克米桑油田位于伊拉克东南部的米桑省,地质情况复杂,存在严重的盐膏层蠕变缩径、垮塌、高压盐水层、井漏等复杂情况,特别是目的层裂缝性漏失十分严重,采用常规堵漏技术收效甚微,在目的层中堵漏既要保证堵漏效果,还要保证完井后的采油作业能建立有效的通道。AGCS27井四开钻进至井深2 932 m发生漏失,先后应用各种堵漏剂进行了20多次的堵漏作业,效果均不理想,最后采用套管传输堵漏工艺,将大颗粒、长纤维堵漏材料,装入套管筒直接送至漏层,对漏层进行封堵,取得了良好的效果,为该井的顺利完钻提供了井眼保证,是一种创新的堵漏工艺,对深井裂缝性漏失的堵漏作业,具有经济性和实用性。

| Abstract: | Lost circulation was frequently encountered in the complex formations in Misan Oilfield in Misan Province of Iraq. Lost circulation, especially those occurred in the reservoir formations, cannot be stopped using conventional techniques. When drilled the Well AGCS27 to 2,932 m, lost circulation occurred, and was not able to be completely controlled after trying various lost circulation materials (LCM) for 20 times. Finally, a casing barrel was used to transfer the large particle, long fiber LCM to the thief zones, and the lost circulation was successfully stopped. As an economic and practical method of lost circulation control, this technology is worth trying in drilling deep wells with fracture-induced lost circulation. |
