摘要
首次采用热模拟实验中配比的方法对未熟有机质生气过程进行了研究,通过热模拟实验建立了龙口地区煤岩理论生气史模型,并在此基础上通过龙口煤岩配比模拟,建立了孤北地区C-P煤系烃源岩生烃演化地质模型,根据地质模型回归出了孤北地区烃气产率计算公式,结合热演化史和构造演化史对孤北地区煤系烃源岩的生气过程及天然气的资源潜力进行了分析,研究发现孤北地区C-P煤系烃源岩主要有两次生气过程,第二次生气量大,是孤北地区煤成气藏的主要气源,估算煤成气的资源量约为110×108m3。
In this paper,the hydrocarbon generation model of crudity organic material is established,and have a detailed analysis of the Hydrocarbon Generation and Accumulation Potential Analysis of C-P Coal Source Rock in Jiyang depression,Gubei Area is presented. The results indicated that the region of interest have twice hydrocarbon generation process,the second one has big yield and good conserve condition,it is the main hydrocarbon source of coal genetic gas reservoir in the area,and gas drived form the resources of coal is about 110 × 108m3.
