摘要
多分支物源汇集的王集地区是泌阳北部斜坡带滚动勘探的重点地区,也是难点地区。该区构造复杂,断裂破碎严重,油藏类型多样化,复合油藏和岩性油藏是现阶段的勘探重点。多物源砂体的交汇造成储层平面展布复杂,对油气运聚的控制作用认识不清,砂体和油水边界预测难度大是王集地区现阶段生产过程中面临的主要难题。选取重点含油小层,精细刻画单砂体的物源方向、砂体展布形态、沉积微相类型、与构造的匹配关系,明确王集地区有利油层分布的区域和层系是当前的首要任务。同时,分层系理清王集地区储层展布特征及储层在油气藏聚集过程中所起的作用,是寻找和发现王集地区剩余隐蔽油藏的有效手段。
Wangji area is an area of multiple braches of provenance and it is the key and difficult area for rolling exploration in northern slope zone of Biyang.The area has the characteristics of complicated structure,various reservoir types and serious broken faulting.At present,the exploration target is compound reservoir and lithologic reservoir.Due to multiple branches of provenance,the reservoir plane distribution is complicated and the understanding of controlling factors on hydrocarbon accumulation is not clear,and the main problems for production in Wangji area are great difficulties in sand bodies and oil-water boundary prediction.Therefore,oil-bearing layers have been selected to carry out fine description of the matching relation between provenance direction of single sand body,sedimentary micro-facies types and the structures,and the first priority in Wangji area is to make clear the favorable oil layers distribution and its layer series.Meantime,making clear the reservoir distribution in different layer series and its role in hydrocarbon accumulation are the effective means to look for and find remaining hidden reservoirs in Wangji area.
