摘要: 本文从地质历史演变出发,重塑了川西北盆地梓渔地区沉积物理藏史、温度史、有机质热演化史;应用TTI值来计算上三受统天然气资源量,并在计算方法上有所改进;根据计算结果,结合该区地质特征,评价了天然气富集程度。经试用效果良好,可普遍用于煤系天然气资源评价。

Abstract: Based on the evolution of geologic history and the reconstruction of sedimentary process, temperature change, and gas generation, this paper calculates by improved TTI method the volume of gas generated in Upper Triassic in Zitong region of Northwest Sichuan .basin .According to the volume calculated as well as the geologic characteristics of this region, this paper evaluates the gas richness in Upper Triassic.The method of evaluating gas resources of coal measure strata introduced here can be commonly applied in other similar regions.

Key words: Natural gas, Resource extent, TTI value, Upper Triassic, Northwest Sichuan
