泥浆对水平孔岩屑运移影响分析

Analysis on Influence of Mud to Cutting Movement in Horizontal Hole

摘要:

泥浆的主要功用之一是通过自身的循环，有效地清除钻孔内破碎下来的岩屑，特别是对于水平孔，可以避免砂床的形成，减少钻孔内的事故。结合室内实验及相关工程应用，采用水力学的方法，对泥浆中影响水平孔岩屑运移的各种参数进行了分析，提出了建立室内实验评价系统的总体构架。

Abstract:

Drilling mud can clean out the cuttings by its circulation, especially for horizontal hole, it can avoid the sand-bed formation and reduce downhole troubles. Based on the laboratory experiment and engineering application, analysis was made on various parameters which affect cutting movement in horizontal hole with hydraulics, and suggestion was made to establish the overall framework for laboratory experiment evaluation system.
