Abstract:

Due to every gas injection candidate reservoirs having different kinds of affective factors, the factors depend on eachr soad ech other, which bring some difficulties in deciding and evaluating to manager, the evaluation index system and the evaluated range of the index was introduced in the paper, the fuzzy optimum screening model of the candidate reservoir for gas injection and its calculate step was established, On the foundation of obtaining the same reservoir parameter weight which was calculated by fuzzy gradation analysis, the fuzzy optimum screening model which applied to screening the unitian rirga injection was successfully established. The example has proved that this method would rightly evaluate and compare the potential of the candidate reservoir to gas injection.

Key words: fuzzy mathematics, optimum screening theory, reservoir engineering, gas injection, reservoir screening
