水基无粘土低固相钻井液在镇泾工区的应用

Application of Water-base Clay Free Low Solid Drilling Fluid in Zhenjing Work Area

摘要:

根据镇泾油田勘探开发一体化、低成本开发战略要求，在设计范围之内尽可能采用新工艺、新技术，以缩短钻井周期，提高作业效率，缩短钻井液对储层浸泡时间，减轻钻井液对储层伤害。在确保安全生产、施工质量的前提下，大胆应用水基无粘土低固相钻井液体系，并采取相关的防范措施,经实践证明能有效地控制井下复杂情况的发生，达到了提高钻井速度、降低钻井成本的目的。

Abstract:

Water-base clay free low solid drilling fluid was applied in Zhenjing oilfield to shorten drilling period, improve operation efficiency, shorten the soakage time of the reservoir with drilling fluid and reduce the reservoir damage caused by drilling fluid. It was proved by practice that the drilling fluid could effectively control the complicated situations in downhole with increased drilling speed and lowered drilling cost.
