[Abstract]:Traditional domestic oil and gas fields have gradually entered the middle and late stage of development, with the decrease of crude oil reserves, the decrease of production and the decrease of economic benefits. Therefore, the development of oil fields must change from "speed scale" to "quality benefit", and take the road of intensive management. It is more and more important to make full use of existing resources, funds, labor force and technical measures, optimize the allocation of resources, and develop existing old oil fields more reasonably, effectively and scientifically. The core problem of oilfield development is optimal control. Oilfield development is a broad field of application of optimization method, which involves production distribution, oilfield development policy and scheme, well location optimization, tertiary oil recovery process control and oilfield strategic planning. Oilfield development is not only a technical activity, but also an economic activity. Influenced by oil price and politics, it is a multi-objective decision making problem in general. Based on the oilfield block angle, the goal of oilfield development is analyzed in the whole process, and the multi-objective optimization is carried out for the development and production. Based on the perspective of oilfield blocks, this paper analyzes the present research situation of oilfield development optimization and multi-objective optimization at home and abroad, expounds the theory of oilfield development and multi-objective optimization, and sets up benefits by analyzing the factors of oilfield block development. This paper analyzes the input-output relationship among the objectives and makes use of the system engineering tools such as DEA to empower several targets. After determining the decision variables of oilfield development, the multi-objective optimization model of oilfield block development is established, and the solving steps of the multi-objective optimization model are defined. An empirical study on the multi-objective optimization model of oilfield block development is carried out. The optimization results of oilfield block development are given through the steps of goal setting, multi-objective weighting, decision variable selection, multi-objective solution and so on. The development suggestions are put forward from the aspects of well pattern density, measure workload, measure cost and so on.
