| 摘 要： | 利用盆地模拟方法对勘探程度较低的莘县凹陷进行了油气生成和排出的定量模拟研究.讨论了模拟所需主要参数的确定方法,对模拟结果进行了地质解释.着重分析了主力生油层系的埋藏受热史、成熟度史及生、排油量史,初步划分了供油单元.研究指出,本区主力生油层系为下第三系沙三中下段,其次为沙四段.与相邻地区比,它们埋藏较浅,经受的最高地温及目前有机质的成熟度均偏低,总体上尚处于主要生油阶段的早中期.因主要排油期发生较晚,致使油气近距离运移为主,禹城洼陷和梁水镇洼陷两个主要油源区控制着凹陷中最有远景区的分布.

| Abstract: | The processes of hydrocarbon generation and expulsion in Shenxian depression are quantitatively studied by using basin modeling. The main parameters required before modeling are briefly discussed. The modeling results are interpreted geologically. The burial and thermal history, the generation and expulsion history of the chief source rock beds are analyzed. The results show that the chief formations of dydrocarbon generation in the depression are the lower and middle members of sha-3 and sha-4 with lower maturity. Up to now they are in the early and middle stages of catagenesis. As the chief expulsion stage is in the Minghuazhen stage, the distance of secondary migration of petroleum is shorter. Yucheng sag and Liangshuizhen sag are the two main oil source areas and control the distribution of the most prospective areas in the depression. |
