【摘要】：國內傳統油氣田陸續(xù)進入開發(fā)中后期,原油儲量下降、產量遞減,經濟效益降低,油田發(fā)展必須由“速度規(guī)模型”向“質量效益型”轉變,走集約化經營的發(fā)展道路,充分利用現有資源、資金、勞動力和技術措施,優(yōu)化資源配置,更加合理、有效、科學地開發(fā)現有老油田越來越重要。油田開發(fā)的核心問題是最優(yōu)控制。油田開發(fā)已經是優(yōu)化方法應用的廣闊領域,涉及產量分配、油田開發(fā)政策與方案、井位優(yōu)化、三次采油過程控制以及油田戰(zhàn)略規(guī)劃等方面。油田開發(fā)不僅是一項技術性強的活動,也是一項經濟活動,受到油價、政治等的影響,總體來說是一個多目標決策問題。基于油田區(qū)塊角度,全過程分析油田開發(fā)的目標,并針對開發(fā)生產進行多目標的優(yōu)化。本文基于油田區(qū)塊視角,分析了國內外有關油田開發(fā)優(yōu)化、油田開發(fā)多目標優(yōu)化的研究現狀,闡述了油田開發(fā)與多目標優(yōu)化理論,通過分析油田區(qū)塊開發(fā)因素,設置了效益、投資、措施成本、措施增油量四大目標,分析目標之間的投入產出關系,利用DEA等系統工程工具,對多個目標進行賦權。確定油田開發(fā)決策變量后,建立了油田區(qū)塊開發(fā)的多目標優(yōu)化模型,明確了多目標優(yōu)化模型的求解步驟。并對油田區(qū)塊開發(fā)多目標優(yōu)化模型進行實證研究,通過目標設定、多目標賦權、決策變量取值、多目標求解等步驟,給出了油田區(qū)塊開發(fā)的優(yōu)化結果。并從井網密度、措施工作量、措施成本等角度提出了發(fā)展建議。
[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.
