根据影响井壁稳定性的因素,即岩石组分及其理化性能(阳离子交换容量、膨胀率、水化值等),研究了塔里木盆地中央隆起泥页岩的组分、坍塌值与膨胀率、水化值、回收率、分散值之间的关系及其影响因素,将该隆起泥页岩分为高膨胀强分散水化坍塌、中分散剥落坍塌、中膨胀强分散垮塌等类型,分析了各类泥页岩井壁不稳定的坍塌机理,提出了稳定井壁的建议.

Based on the factors influencing the wellbore stability, such as rock composition and its physical and chemical properties (cation exchange capacity, expansion ratio and hydratability) , the relationships between shale composition, sloughing value, expansion ratio, hydratability, recovery ratio and dispersing value and their influencial factors were studied in the central uplift of Tarim Basin. The mudstone and shale are divided into high expansion and high dispersed and hydrated sloughing, mid-dispersed sloughing and mid-expansion and strong dispersion sloughing, the sloughing mechanism of wellbore unstability. various mudstones and shales are analyzed,and suggestions for wellbore stability are put forward.
