泡沫泥浆压力平衡钻进工艺

Balanced Drilling Process with Foam Mud

摘要:

从深水位水井钻探严重漏失的实际出发，根据压力平衡钻进原理，提出使用超低密度泡沫泥浆在深水位水井中进行压力平衡钻进的可能性，对泡沫泥浆压力平衡钻进的原理和工艺进行探讨，并简要介绍了在陕西乾县水井施工应用该工艺的情况。

Abstract:

Considering the severe circulation loss during drilling in water well with the deep water table, the feasibility of application of balanced drilling with foam mud of extra low density to water well drilling with the deep water table is proposed. The foam mud balanced drilling principle and process are discussed. The application of the process in water well drilling in Qian County, Shanxi is briefly introduced.
