摘　　要：泌阳凹陷油气分布平面上明显受生油中心区的控制,主要围绕生油中心区呈环带状分布,呈现"满盆"含油,正向构造带是主要聚集区;纵向上"层层"含油,主力油层为核三上段2-4油组;油藏类型多,南北差异大并呈互补,构造岩性油藏为主。利用翁氏模型、油田规模序列法、龚帕兹模型、帚状模型等,对泌阳凹陷探明储量增长趋势进行预测,认为泌阳凹陷资源量4×108t左右,剩余资源量1.4×108t,勘探潜力较大,近期仍然可以保持较高的探明储量增长速度。Biyang sag hydrocarbon distribution is influenced by oil generation central area,which shows belt-shaped distribution around oil generation central area,presents 'the full basin' oiliness.The forward structure belt is the main accumulation area,on longitudinal 'layer upon layer' oiliness,main oil layer is He III up-segment 2-4 oiliness.The oil deposit type are various,the north and south difference is big and assumes supplementally,structure lithologic deposit primarily.Using Weng model,the field size order method,Gompertz model,broom model and so on,Biyang sag reservoir growth trend has been predicted.It is thought Biyang sag reservoir quantity is 4×108 t,residual resource quantity is 1.4×108 t,the exploration potential is big,in the near future the high proven reserves rate can still be maintained.
