摘要

从岩石力学、地球物理测井、工程录井、环空水力学和钻井液化学等方面分析定向井井眼稳定问题,建立地层孔隙压力剖面、地层坍塌压力剖面和地层破裂压力剖面,以实现对钻井液性能、井身结构及其它工程参数的优化设计。

Abstract

In order to realize optimized design on drilling fluid prpperties, bore hole structure and other parameters, a comprehensive analysis on bore hole wall staility in directional wells from point of view of rock mechanice, geophysical logs, engineering data collection, annulus hydraulics and drilling fluid chemistry was conducted and formation prore pressure profile, formation sloughing profile and formation breakdown pressure profile were established.
