Abstract:

It is difficult to analyze the performance of multi-layered sandstone reservoir,because there is not adequate dynamic
detection data for producers and injectors. A new approach to the question is presented. Based on microscopic percolation
mechanism and macroscopic development characteristics,after the relationship between cumulative production of single well
and the dynamic and static factors which affect waterflood development,such as reciprocal value of filtrational resistance,
average pore throat radius,reciprocal value of interlayer frequency,net thickness and monthly liquid production is researched,
and a discriminant matrix is established to determine the weights of the various factors. Then distribution coefficient of every
producer is gotten,so are the layered accumulative production and performance. The instance validation results show that the
method is suitable,and can be used to analyze the performance of wells without dynamic detection data,for guiding the later
exploitation.
