摘要
为了实现对天然气资源量的定量模拟,提出“聚气系统”的概念,并利用盆地模拟技术建立了聚气系统天然气资源量动态模拟模型.聚气系统是包含一个聚气区和若干与其相关供气区的天然气生、运、聚、散的自然系统.所建立的天然气资源量模拟模型包括了地史、热史、生排烃史和天然气运聚史,考虑了天然气运聚过程中的溶解作用、扩散作用和断层散失作用.
In order to quantitatively evaluate the natural gas resources in one exploration object, the concept of Gas Accumulating System——a physical system of natural gas generation, migration and accumulation which includes one accepting area and several providing area——is put up. Using basin modeling technique, on the basis of geological history, thermal history, hydrocarbon generation and expulsion history, we set up the model of natural gas migration and accumulation, which takes into consideration the resolution, diffusion and losing through the faults of natural gas. This model is applied to the calculation of the gas resources in an area of a basin in west China, the result is consistent with that come from other methods.
