基于多因素关联关系的油田开发措施结构优化方法研究

OPTIMAL METHODS BASED ON RELATIONSHIPS BETWEEN AFFLUENT ASSOCIATED FACTORS FOR OIL FIELD DEVELOPMENT MEASURE ARRANGEMENT

从油田开发历史动态信息出发,研究分析了影响油田措施产量的各种因素,利用功能模拟原理(微分模拟方法与神经网络方法)建立了油田措施产量与其影响因素的非线性关联关系。在此基础上,建立了基于措施产量最大、成本最低、效益最好的措施结构优化模型,较好地解决了油田措施产量、成本、工作量的最优构成问题,并成功应用于油田措施结构优化。

From the existence of dynamic information of oil field development , all kinds of factors affect measured production are analyzed, and the non lineal relationship between measured production and corresponding factors is established by the aid of functional simulation principle, i. e. differential coefficient simulation method and never net method. With the well built relationships , optimal measure arrangement modules attend to maximum measured production, minimum cost and maximum profit are provided, those are successfully applied in tactics and solve well questions on the optimal arrangement of measured production, cost and operation.
