摘要
濮卫地区位于东濮凹陷中央隆起带北部,油藏控制因素复杂,其勘探程度较低。利用生物标志化合物和含氮化合物分析等方法对该区进行油气运移研究,发现油气平面运移特征表现为古云集—文明寨地区有2个油气充注区,一个是卫东断阶带下降盘洼陷内侧云3块,另一个是卫城地垒;濮卫洼陷西翼油气注入点为卫42块,沿断层下降盘向南充注,并由洼陷向地垒上运移;濮城南—户部寨地区油气除来自濮卫南部次洼外,还接受了南部前梨园或柳屯洼陷沙三段高成熟的油气。纵向运移特征则呈现为以层析作用为主的垂向运移的特点。
Pu-Wei Region is located in the northern part of central uplift zone,Dongpu Depression.The exploration degree is low in its sub-depression and the control factors of oil pool are complex.Through utilizing the biomarker and nitrogen compounds to research the hydrocarbon migration characteristics in the region,it is found that there are two hydrocarbon injection areas,i.e.Yun3 block within the sub-depression of Weidong fault downthrow wall and Weicheng horst,for the hydrocarbon migration characteristics in plane in Guyunji-Wenmingzhai Region.Hydrocarbon injection area is Wei42 block in the western flank of Pucheng-Weicheng sub-depression,with injection towards south along the downthrow wall of fault and with migration direction from the sub-depression to the horst.At South Pucheng-Hubuzhai Region,the hydrocarbon comes from the high-mature hydrocarbon of Es3 reservoir in the southern Qianliyuan or Liutun sub-depressions except for the southern sub-depression of Pucheng-Weicheng Region.The vertical hydrocarbon migration shows the characteristics of vertical migration,which is mainly the chromatography.
