【摘要】：国内传统油气田陆续进入开发中后期,原油储量下降、产量递减,经济效益降低,油田发展必须由“速度规模型”向“质量效益型”转变,走集约化经营的发展道路,充分利用现有资源、资金、劳动力和技术措施,优化资源配置,更加合理、有效、科学地开发现有老油田越来越重要。油田开发的核心问题是最优控制。油田开发已经是优化方法应用的广阔领域,涉及产量分配、油田开发政策与方案、井位优化、三次采油过程控制以及油田战略规划等方面。油田开发不仅是一项技术性强的活动,也是一项经济活动,受到油价、政治等的影响,总体来说是一个多目标决策问题。基于油田区块角度,全过程分析油田开发的目标,并针对开发生产进行多目标的优化。本文基于油田区块视角,分析了国内外有关油田开发优化、油田开发多目标优化的研究现状,阐述了油田开发与多目标优化理论,通过分析油田区块开发因素,设置了效益、投资、措施成本、措施增油量四大目标,分析目标之间的投入产出关系,利用DEA等系统工程工具,对多个目标进行赋权。确定油田开发决策变量后,建立了油田区块开发的多目标优化模型,明确了多目标优化模型的求解步骤。并对油田区块开发多目标优化模型进行实证研究,通过目标设定、多目标赋权、决策变量取值、多目标求解等步骤,给出了油田区块开发的优化结果。并从井网密度、措施工作量、措施成本等角度提出了发展建议。
[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.
