摘要
利用油气藏地球化学参数和指标 ,对埕岛复杂油气田的油气聚集、运移系统进行了研究 .按油气的地球化学特征和储集空间的差异性将其划分为埕北断裂及主体带、斜坡带和CB30潜山带三大类油气聚集系统 ;按油气源、运移途径等的不同将其划分为三种油气运移系统 ,即埕北凹陷 -埕北断裂及主体带、沙南 (渤中 )凹陷 -斜坡带和渤中、桩东凹陷 -GB30构造带 ;最终归纳出单凹陷 -它源 -断裂带式、单凹陷 -它源 (自源 ) -斜坡带式和双凹陷 -它源
The hydrocarbon migration and accumulation system analysis to a complicated oilfield is carried out for Chengdao oilfield based on analytical parameters of reservoir geochemistry and integrated geological data.Three hydrocarbon accumulation systems and six sub-systems are identified according to the differences in characteristics of geochemistry.Three hydrocarbon migration systems are divided according to the results of oil-source rock correlation and the differences in migration pathways.Finally,three models of the hydrocarbon migration and accumulation systems are proposed for the studied area.The results will shed new light onto the exploration and development of Chengdao oilfield in the future.
