摘要
根据正交设计方法和模糊数学原理 ,在室内试验及数值模拟研究的基础上 ,考虑到各项技术和经济指标的综合影响 ,建立了基于模糊综合评判模型的复合驱注采参数优化设计模型。同时 ,以孤东油田七区西Ng5 4- 6 1层复合驱试验为例 ,对化学剂组合方式、配方浓度、段塞尺寸、注采速度、注入方式、注入时机等参数进行了优化。综合分析表明 ,该方法能够用尽可能少的方案寻求各参数间的最佳协同效应 ,且便于决策。
The experimental study and numerical simulation of ASP flooding are made, and a set of fuzzy comprehensive judgement models used for optimizing design of injection production parameters of ASP flooding solution are presented by using quadrature design method and fuzzy mathematics, with comprehensive consideration of the effects of each technical and economic target. It can seek for the optimum cooperation of parameters among the least projects and be easy to make a strategic decision. This paper also presents an example. The parameters, such as chemistry composite mode, system consistency, slug size, injection production rate, injection way, chemistry injection opportunity, are optimized in the ASP flooding test of western 7th region in Gudong oilfield. Application results show that this project has a good economic benefit.
