| 摘 要： | 由于复杂边界、平面非均质性和井网完善程度对复杂断块面积波及系数的影响,因此在常规注采井网均质油藏水驱面积波及系数的基础上,引入复杂边界校正系数、地层非均质性与注采井网关系校正系数、井网完善校正系数来修正复杂断块见水后的面积波及系数,得到其计算表达式。应用此法计算江苏油田庄2断块2009年7月底的面积波及系数,其计算结果与数值模拟结果相差仅3.6%,证实了该理论修正方法的合理性。

| Abstract: | Complex boundary,areal heterogeneity and the coverage degree of well array have their impacts on areal sweep efficiency of a complex block.Based on the areal sweep efficiency of conventional flooding pattern for homogeneous reservoir,correction coefficients are introduced to revise the areal sweep efficiency after water breakthrough in faulted block reservoirs,including complex boundary,the relationship between heterogeneity and flooding pattern,and well pattern coverage degree.The computational expressions... |
