油田水驱开发系统结构分析

Analysis on development system structure of water flooding in oilfield

油田水驱开发系统复杂,指标繁多,指标之间相互有部分交叉、覆盖、包含等成分。为了理顺这些指标之间的结构、关系,应用系统论、控制论、信息论,分析了水驱油田开发系统,建立了油田开发系统结构及其信息表征体系结构,明晰了油田开发巨系统的结构,获取了水驱油田开发巨系统、子系统、孙系统及系统之间的协调性与整体性的外在信息表征体系。这些指标归属3大体系:地质状态指标体系、控制状态指标体系、生产状态指标体系。将这些指标综合起来即为综合评价水驱油田开发效果的主要初始指标体系。

Development system of water flooding of oilfield is complex with a large number of indexes intersecting, overlying and containing among each other. In order to understand their structure , relationship, applied system theory, cybernetics and information theory, water flooding oilfield development system is analyzed, oilfield development structure and its characterization structure is established, huge-system structure is determined, and not only huge, sub, and sub-sub-system is obtained, but also coordination among their systems and the whole exterior information characterization system is obtained. These indexes are divided into three systems： geologic status index system, control status index system and production status index system. Integrating them together is main primary index for comprehensively evaluating effects of water flooding oilfield.
