新疆麦盖堤地区高密度钻井液技术

Application of high density drilling fluid in Maigaidi area of Xinjiang

新疆麦盖堤地区地层复杂,钻井过程中经常发生喷、漏、塌、卡等事故。介绍了高密度钻井液在麦4、麦6和麦10井中的应用,对使用技术和效果进行了对比。实践证明,高密度钻井液在麦盖堤地区的应用是成功的,井壁稳定性好,井径规则,井下事故少。但在使用高密度钻井液时应注意控制好钻井液的流变性、粘度、切力和矿化度,降低粘土含量,防止地层损害。

Characteristic of Maigaidi area of Xinjiang Uygur Autonomous Region is introduced. High density drilling fluid was applied in the said reservoir to solve the problems encountered in the drilling operation. Optimum formula of drilling fluid system is seeked and the function mechanism is also presented. Subject terms: Drilling Fluid; Mud Weight; Drilling Problem
