| 摘 要： | 在国内Ⅰ、Ⅱ、Ⅲ型干酪根的三组模拟实验资料基础上,经过生烃产物油气配方的摩尔组成计算,应用PR状态方程计算了生烃产物的PVT相图;根据生烃产物的气油比和PVT相图特征分析发现,Ⅰ、Ⅱ型干酪根的油气生成相态具有两种类型,即“油相型”和“气相型”,两者的Ro分界线分别在1.5%~1.6%和0.9%~1.0%之间;而Ⅲ型干酪根的生烃产物均表现为“气相型”。

| Abstract: | Based on three domestic groups of simulation experiment data of kerogen typeⅠ,Ⅱ, and Ⅲ, and through the calculation of mole composition of hydrocarbon-generation products,pvt phase maps are computed by applying pr state equation;analysis to oil/gas ration of hydrocarbon-generating products and PVT phase maps shows there are two types of hydrocarbongenerating phase behavior of kerogen typeⅠandⅡ, i.e.,“oil phase”and“gas phase”, the critical percentage for Ro is 1.5%1.6% and 0.9%1.0% respectively; and the hydrocarbon generating products by kerogen typeⅢare all“gas phase”. |
