摘要
介绍了朝平2井地层特点及其井身结构。在上部地层直井段和大斜度井段优选小阳离子聚合物钻井液、在下部地层水平井段优选油包水钻井液。现场应用结果表明,小阳离子聚合物钻井液抑制能力、防塌能力、携砂能力强、润滑性好、性能易于维护;油包水钻井液性能稳定、携砂和润滑效果好。两种钻井液均能满足相应井托的钻井施工需要,避免了井下复杂情况的发生。
The characteristics of Chaoping-2 well are introduced. Cationir polymer mud is adopted in the upper section, and water-in-oil drilling fluid is used in the horizontal section. It is indicated that the two kinds of drilling fluid can satisfy the requirement of drilling engineering .
