摘要： 塔中台地边缘上奥陶统良里塔格组颗粒灰岩段发育良好的储集层, 是近几年来重要的勘探对象。为剖析该储集层孔隙发育形成过程, 依据岩石学和碳酸盐岩沉积理论, 对成岩演化进行系统研究, 建立了适合塔中地区的各成岩阶段的岩石学识别标准; 建立单井取心段的成岩演化剖面; 在区域上确定各成岩阶段胶结物的分布丰度和成岩作用的强弱。这些工作对于研究储集层发育的控制因素具有重要作用。

Abstract: Some high-quality reservoirs exist in Lianglitag limestone member of Upper Ordovician in Tazhong platform margin in Tarim basin, which have become significant targets for petroleum exploration breakthrough in recent years in this area. This paper presents indepth study of diagenesis evolution of the carbonate sediments in lithology and sedimentology, including the establishment of relevant lithology identification standards for each diagenetic stage and the cross section of diagenesis evolution for coring sections of single well as well as regional distribution and abundance of cements in various diagenesis stages and their variations of diagenesis. The results are helpful to research the controlling factors of reservoir development in this area.

Key words: carbonate rock, diagenesis evolution, lithology evidence, cathodeluminescence
