研制的抗高温油包水钻井液实现了抗高温 2 2 0℃ ,其抗高温乳化剂复配后具有优异的乳化稳定性 ,用它在现场成功地将原抗温 180℃的油包水钻井液改造成抗高温 2 2 0℃的钻井液 ,在葡深 1井四开下部 (4 5 90～ 5 5 0 0 m)井段应用 ,圆满地解决了 16 0 d钻井和测井施工的高温稳定性、悬浮性、携屑性、滤失性问题。施工期间 5 0多次起下钻具和测试仪器 ,都能下到井底 ,无阻卡显示。解决了松辽盆地深层钻井的钻井液抗高温技术问题。
Developed high temperature oil-in-water drilling fluid to achieve a high temperature 2200C, the high temperature emulsifier compound with excellent emulsion stability, with its successful in the field of the original temperature of 180 DEG C water-in-oil drilling The drilling fluid reconstructed into a high temperature resistance of 220 ℃ was applied to the lower part of the Sizhong 1 deep well (455 ~ 5500 m), which successfully solved the high temperature of 16 0 d drilling and logging Stability, Suspension, Carrying debris, Filler problems. During the construction more than 50 times from the drill and test equipment, can be down to the bottom, no resistance card display. Solve the Songliao Basin deep drilling drilling fluid high temperature technical problems.
