Abstract

Abstract:

The interlayer and interwell producing degree are very different in the water drive reservoir during the stage of
extra-high water cut. Based on the relational expression of the recovery，the sweep efficiency and the displacement efficiency，
this paper introduces the conception of flushing efficiency coefficient to describe producing degree of multilayer heterogeneous
reservoir and establishes the relational expression of recovery and flushing efficiency coefficient of the multilayer heterogeneous
reservoir. With the result of the numerical simulation，we calculate the flushing efficiency coefficient of every sublayer. We also
find out the difference of interlayer producing degree by analyzing the variation of cumulative distribution curve shapes，and
average values and variability of flushing efficiency coefficient before and after the structural regulation of fracturing，water
plugging，subdivision water injection and so on. The result illustrates that the cumulative distribution curve shifts towards
right whose slope becomes bigger，the variability of flushing efficiency coefficient becomes smaller and the average values of
flushing efficiency coefficient becomes bigger. Those demonstrate that the producing degree of heterogeneous oil layers and
uneven producing condition has been improved，and quantitative analysis of the producing degree of the oil layers has been
achieved. Therefore，this paper provides a new method and theoretical foundation for the producing degree of heterogeneous
oil layers during the stage of extra-high water cut.

Key words: fine tapping potentialities, oil layer heterogeneity, flushing efficiency coefficient, producing degree, structural
regulation measure
