Abstract:

Well-bore collapse in Naduzu shale has been the peimary factor that interferes the drilling in Huacha, Nakun area in Bese Basin, Guangxi. This paper focuses on the mineral content, pore and fissure configuration and the physiochemical properties of Naduzu shale,and provides scientific basis for researching the unstable factors of the well section in Naduzu, and the effective measures of preventing well collapse.

Key words: Anti-sloughing mud, Clay mineral, Clay chemistry, Clay swelling, Clay composition
