阜东斜坡-北三台凸起南斜坡构造有利,岩性勘探的潜力巨大,地层压力变化较大。通过测试、测井、地震资料对该区的地层孔隙流体压力进行较详细的研究后发现,在平面上以西泉鼻隆为封隔带其以北基本为低压区,南部为高压区。从垂向压力分布来看,在浅层具有旋回式压力分布的特征,向深层存在两个异常压力封存箱,一是中上侏罗统为主发育的异常压力封存箱,二是中下侏罗系统-三叠系为主发育的异常压力封存箱。
The Fudong slope - the north Santai uplift southern slope is favorable in structure, and has great potential for lithologic exploration and great changes in formation pressure. Through testing, logging and seismic data, the formation pore fluid pressure in this area is studied in more detail. It is found that in the plane, Xishuobonluo is the basic zone of low pressure zone to the north and high pressure zone to the south. From the vertical pressure distribution point of view, there are characteristics of cyclonic pressure distribution in the shallow layer, there are two abnormal pressure storage boxes to the deep layer, one is the abnormal pressure storage box with the predominate development of middle-upper Jurassic and the second is the middle- Lo system - Triassic-based abnormal pressure storage box.
