摘要: 用盆地模拟方法综合研究陆相泥质源岩水溶相、扩散相、油溶(气)相和游离相四种形式的综合排烃作用,探讨13种主要的地质因素对各相态形式相对排烃量的影响及其相对贡献量大小.研究表明,处于不同埋深阶段的陆相泥质源岩排油气相态特征不同,影响因素不同;在一般地质条件下,我国陆相泥质源岩以游离相、油溶相、水溶相和扩散相排出的天然气量分别为49%、11%、18%和22%左右,以游离相、水溶相和扩散相排出的油量分别为92%、8%和0%左右.

Abstract: The effects and relative contributions of thirteen major geological factors to the modeling results of hydrocarbon expulsion,in separate-phase,in water solution,in oil solution (of gas) and by diffusion from shale source rocks have been comprehensively and quantitatively studied by applying basin modeling technique and uncertainty analysis methods.The research results show that the characteristics of hydrocarbon expulsion in different phases from shale source rocks during their burial history are different,and the major geological factors are also different.Under general geological conditions for nonmarine shale source rocks in China, the relative amounts of natural gas expelled in separate-phase, in oil solution, in water solution and by diffusion are about 49%, 11%, 18% and 22%, respectively; the relative amounts of liquid oil expelled in separate-phase,in water solution and by diffusion are about 92%,2% and 0%,respectively.
