塔里木盆地巴楚隆起石炭—二叠系碳酸盐岩成岩作用

用显微镜法、染色法、镜煤法、铸体鉴定法、阴极发光法、X－衍射等方法研究了巴楚地区石炭系、二叠系成岩作用，证明它经历了压实、泥晶化、胶结、溶蚀、云化、重结晶、硅化、裂缝等成岩作用；经历了海底成岩环境、大气淡水成岩环境、浅埋及深埋成岩环境、表生成岩环境。各种成岩作用不断改变着石炭系、二叠系的储集性能，形成巴什托－亚松迪－带小海子组白云岩和巴楚组白云岩两个较好的储层。各种成岩矿物、石英加大、有机质成熟度、X－衍射的资料证明本区成岩阶段大致相当于Schmidt成岩阶段的“中期成岩阶段”。

DIAGENESIS OF THE CARBONATES OF CARBONIFEROUS AND PERMIAN IN BACHU AREA OF TARIM BASIN

Bachu area has gone through compaction, micritization, cemetation, dolomitization and silicification, proved by microscope. It has gone through marine diagenetic environment, meteoric diagenetic environment, shallow and deep buried diagenetic environment, and mode of diagenesis has been changing storage capability. According to diagenetic mineral, quarts largen, organic matter maturity, it has reached telodiagenesis A.
