ABSTRACT: Oil field waterflooding is a complex man-controlled
systematic behavior, and the related evaluation methods vary greatly. This paper
put forward a fuzzy comprehensive method of evaluating controlled development
level by analysis of the macroscopic evaluation to oil field waterflooding
effect with combination of original reservoir geological state. This fuzzy
evaluation technique bears unique advantages because there is little difference
among evaluation indexes which represent the dynamic and static state of
regional neighborhood of development units (blocks, Production Company, etc.).
Not only the mathematical method for evaluating oil field waterflooding effect
is set up, but also the method is applied in three blocks of D oil field. The
calculated results show the effectiveness and practicability of the method.
