河南油田三口大斜度多目标井的泥浆技术

Mud Technology for Three Multiple Target High Angle Wells of Henan Oil Field

河南油田近期完成了三口多目标大斜度探井B215井、南44井和南46井。本文论述了两性离子聚合物及无荧光润滑剂ZRH—Ⅰ在这三口井中使用的效果,该泥浆体系处理剂品种少,抑制防塌效果好,携岩能力强,性能稳定,润滑性好,不影响录井。

Mud technology for three multiple target high angle wells is introduced . Mud system adopted is amphoteric polymer mud . It is shown that adding 3% lubricator ZRH- I can satisfy the demand of mud lubricity in high angle well , the above mud system has the advan- tage of good inhibity and cuttings transportation property.
