马岭油田北三区延10储层宏观非均质性研究

Macroscopic heterogeneity of the Yan 10 reservoir in Beisan area,Maling oilfield

  • 摘要: 马岭油田北三区延10储层主要发育平行层理、交错层理、斜层理等层理类型,韵律特征为多期次正韵律叠加;从上到下沉积相属于从曲流河相到辫状河相的过渡,从上到下小层非均质性增强,推测由于辫状河比曲流河河道变化更加频繁,沉积更加复杂导致;研究区平面上的非均质程度较强,对油田的实际开发生产影响程度较大。

     

    Abstract: In Yan 10 reservoir from Beisan area of Maling oilfield,parallel bedding,cross bedding and oblique bedding were mainly developed and the multi periods positive rhythm superposition was the main characteristics.From top to bottom,the sedimentary facies were from meandering to braided river facies transition,and the reservoir heterogeneity was enhanced.It was predicted the braided river changed more frequently than meandering river and the deposition was more complicated.Laterally,the heterogeneity degree in the study area was strong,which would greatly affect the actual production of oilfield.
