川西龙门山前构造带液欠提速适应性研究

Study on adaptability of liquid underbalanced acceleration in Longmen piedmont tectonic belt

本文通过开展川西龙门山前构造带液体欠平衡钻井技术适应性研究,对液体欠平衡施工井段优选,论证其可行性,制定液体欠平衡提速方案,有效地降低钻井液密度,提高钻井速度,缩短钻井周期。

The adaptability of liquid underbalanced acceleration in Longmen piedmont tectonic belt is carried out in this paper by optimization of the liquid under balanced well to verify the feasibility of the technology and formulate liquid underbalanced acceleration plan,which can reduce the density of drilling fluid,improve the drilling speed,and shorten the drilling cycle.
