Abstract: Oil and gas field development program includes many tech-nology economic targets, their quantities and units aren’t con-sistent. These technology economic target values are dependent on or contradiction each other sometimes, therefor, we can’tchoose the best development program, by direct comparing one or all technology economic target values of development pro-gram. And the development program is good or bad on one tar-get is relative, has not definite boundary and is fuzzy. Conse-quently, it is rational choosing the best development program.We must consider all target information and specific property and proceed comprehensive evaluation. Scholars studied the comprehensive evaluating method of development program opti-mization before, but these methods were shortage. For this rea-
son, we apply multiple attribute decision theory and fuzzy theo-ry, in this paper, a fuzzy decision-making technique was devel-oped to evaluate an oilfield development program for rational, accurate and operated easily. It based on studding these fuzzy decisions-making techniques of an oilfield development program that existed. The paper presented a successful example.
