摘要
潜江凹陷潜40油组沉积时期,气候半干旱,物源规模中等,受潜江组同沉积断层广华断层、蚌湖断层影响,在下降盘形成北东向展布的深洼槽,上升盘为水下古高地区,在断层下降盘发育水下分流河道、河口坝砂体,断层上升盘发育滩坝砂体,自身烃源发育,综合评价指出该区具有多类型岩性油藏勘探潜力,在该思路的指导下勘探获得新发现。
At the period of sediment,Eq4^0 formation in Qianjiang sag displayed semi-arid climate and mid-sized source.Under the influence of Guanghua Fault and Benghu Fault,a north-east spread sag was formed in its downdropped block where underwater distributary channels and estuary dam sand bodies developed well while underwater palaeouplift was formed in its upthrown side where beach bar and hydrocarbon source developed well.The comprehensive evaluation indicates that this area has exploration potential for multi-type lithologic reservoirs and under the guidance of such an evaluation breakthrough has been made in exploration.
