朝阳沟油田扶余油层油源及运移路径模拟

摘要：为研究朝阳沟油田扶余油层油气富集规律,系统收集了三肇凹陷原油地球化学测试数据,根据生物化学标志物特征探讨了朝阳沟油田油气来源;在埋藏史恢复、生排烃史恢复、储层物性分析的基础上,采用盆地模拟软件,应用流体势原理,模拟油气从三肇凹陷到朝阳沟阶地的运移路径。结果表明,朝阳沟油田油气来源于三肇凹陷,通过断层垂向连通作用和砂体侧向输导作用,由南向北运移。朝阳沟阶地北段先行聚集油气,并向南段调整,形成现今油气聚集局面,朝阳沟油田油气富集区是有效运移油气量和圈闭共同作用的结果。

Oil Source and Migration Pathway Simulation of Fuyu Oil Layer in Chaoyanggou Oil Field

Abstract: Several oil pools have been found in Fuyu oil layer in Chaoyanggou oil field. Biomarker was used to analysis the oil source. In order to simulate oil migration pathway from source area to chaoyanggou oil field , detail research has been done using basin modeling software such as burial history restoration , oil generation and expulsion ,and porosity analysis of reservoir .Based on fluid potential therory ,the oil migration pathway was calculated. The result is that the oil from Chaoyangguo oil field come from Sanzhao depress , oil mirgate from Sanzhao depress southward and accumulate in the north part of Chaoyanggou terrace first , then regualte to south , and makes oil distribution today.
