中文摘要： 智能井技术具有实现单井高产、大幅度提高采收率、最经济高效开发油气田等方面的优势并适用于各种油气藏。本课题在对国外主要拥有智能井技术的WellDynamics、Baker、Weatherford、Schlumberger等四大公司的广泛调研基础上，通过技术解剖、机理分析消化与自有技术基础相结合，对ICV等关键器件自主设计开发，进行研制适合国内技术基础的智能井系统。智能井多层合采方式非常适合我国的多层系油藏情况，通过研究智能井生产优化控制模型即通过各个层段控制阀的节点组合控制，达到优化分配各个油层的压力、产量、注水量，最终实现单井产量最优的目的。本项目以自主研制的智能井系统以及物理实验分析，结合运筹学原理、最优化等理论，建立生产优化控制模型。该模型研究不同节点组合下的流入动态规律、层段控制阀流入动态特性、含水上升规律，得出单井产量最优的节点组合规律，形成一套智能井生产优化控制理论与方法。

英文摘要： Intelligent Well technology has high yield, greatly improve the single well recovery, the most economic efficient develop oil and gas fields, and other aspects of the advantage and applies to all kinds of reservoirs. This topic in major foreign Intelligent Well technology of WellDynamics, Baker, Weatherford, Schlumberger company''s extensive research foundation, through the technology anatomy, digestive and mechanism analysis of own technology foundation, and the combination of key components for ICV independent design, development, manufacturing technology for domestic based intelligent well system. Intelligent well in multilayer commingling is very suitable our country of multilayer reservoir situation, through the research intelligent optimization control model that is production through each layer of the node combination between everyone internal control valves to achieve the optimal allocation of each reservoir pressure and production, injection, and finally achieve the purpose of single well the optimal production. This subject to independent research and intelligent Wells system and physical experiment analysis, with operational research principle, the optimization theory, establish production optimization control model. The model research different combinations of node into the dynamic rule, internal con
