Study On Multi-objective Optimization Of Oilfield Block Exploitation

Traditional domestic oil and gas fields have moved into the later development, crude oil reserves decrease, production decline, economic efficiency reduce, the development of oil fields must be changed from "speed and scale" to "quality and efficiency", taking the development road of intensive management. It is increasingly important to make full use of existing resources, capital, labor and technical measures, to optimize the allocation of resources, to develop the existing old oilfields more reasonably, effectively and scientifically.This paper, on the perspective of oil blocks, analyses the oil blocks factors in terms of development effectiveness, production, costs, investment, and based on the factors it establishes an multi-objective optimization model of the oil blocks development. It sets multi-objective of oil blocks development, analyzes the relationship between the input and output objectives, uses DEA and other systems engineering tools to empower multiple objectives, determines the decision variables,, uses operations research methods such as multi-objective optimization model to solve the problem. Finally, the development of oil blocks in multi-objective optimization studies is summarized.
