THE APPLICATION OF THE FUZZY- GRAY- ELEMENT METHOD IN THE OPTIMIZING AND MAKING-DECISION OF DEVELOPMENT PROJECT OF THE GAS INJECTION DRIVE

摘要

The Optimizing and Making-decision of development projects of the Gas Injection Drive is a rather complicated system engineering, and influenced by many fuzzy factors with gray information. According to the item characteristics of the gas injection drive development, This text designed the index system of making-decision, constructed the project of the making-decision, and established the complex Fuzzy-gray-elements and criterions of the making-decision, combined with numerical simulation technology of gas injection drive development for increasing the more recovery ratio of the oil field in the waterflood's later period, computed the economic and technique indexes of the various gas injection drive development projects, applied the much target optimization method, properly achieved the making-decision's analysis and appraises of development projects.
