马岭油田中一区延10储层分类及剩余油分布规律研究

Research on Zhong I area Yan 10 reservoir classification and residual oil distribution law in Maling oilfield

  • 摘要: 马岭油田中一区位于鄂尔多斯盆地伊陕斜坡构造单元的南西部,经过30多年的滚动勘探开发,目前已进入快速递减期,剩余油分布更加零散、复杂。基于现有的地质资料和低渗油田储层的实际情况,选择了小层砂体平均厚度、孔隙度值、渗透率值以及含油饱和度值四个参数对研究区延10储层进行了储层分类评价,将研究区储层分为一、二、三类。通过对中一区生产井生产动态资料的分析,结合油田开发至今历年来地层压力的变化情况,确定了剩余油的分布范围,总结出了剩余油的分布特征,为油田开发后期剩余油开采提供重要依据。

     

    Abstract: Zhong I area Yan 10 reservoir in Maling oilfield is located in the south west of Yishan slope tectonic unit of Ordos basin.After 30 years progressive exploration and development,it has entered rapid decreasing period.Residual oil distributed scattered and complex.Based on the existing geological data and the real situation of low permeable oilfield,four parameters as substrata avarage thickness,porosity,permeability and oil saturation have been selected to evaluate the reservoir classification of Yan 10 reservoir,the study reservoir is divided into one,two and three kinds.According to Zhong I area production well dynamic data analysis,combined with the change of stratum pressure during the oilfield development,the residual oil distribution is determined,the distribution characteristics of the residual oil is summarized,which provided important basis for residual oil exploitation in oil field later development.
