苏北盆地低电阻率油层的识别及其分布

利用交会图法、人工神经网络法、地质综合法等对苏北盆地低阻油层进行了定性和定量识别，以油砂体为最小作图单元，并突出构造的影响，对苏北盆地低阻油层的分布规律进行了研究。结果表明，苏北盆地低阻油层主要集中于高邮凹陷的沙瓦构造带和金湖凹陷的卞东油田和闵桥油田中的阜三段，尤其是集中在E1f2^1-3-E1f3^1-6层。苏北盆地低电阻率油层主要分布在三角洲前缘的席状砂微相及正韵律的上部和反韵律下部的薄层砂之中。根据此方法识别出苏北盆地新的含油层，扩大了含油层的厚度及面积，增加了原油产量，取得了较好的经济效益。

Identification of the low resistivity reservoir and its distribution in Subei Basin

The low resistivity reservoir in Subei Basin was qualitative and quantitative identified by using intersection grap method,artificial nerve network method and integration of geology method.And the distribution of the low resistivity reservoir was studied on the basis of taking the reservoir sand as the minimum drafting unit and emphasizing the structural factors.The results indicate that the low resistivity reservoir mainly distributed in Shawa structure belt of Gaoyou depression,and the Biandong Oilfield a...
