泵吸反循环钻进中循环液中断的故障树分析

The Fault Tree Analysis of Interruption of Fluid in Pump Suction Reverse Circulation Drilling

循环液中断是泵吸反循环钻进工艺中最为普遍的问题之一。根据故障树 (FTA)分析原理 ,介绍了泵吸反循环钻进中循环液中断的逻辑分析方法 ,为制定纠正和预防措施提供重要依据。

Interruption of fluid is one of the common problem in pump suction reverse circulation .Based on the principle of Fault Tree Analysis (FTA), the logical analysis method for interruption of fluid in pump suction reverse circulation is introduced and provide important basis for correcting and precautionary measures (by Sun Kejia & Feng Yuguo)
