油田水驱开发动态系统预警指标体系的构建

Construction of indicator system of early warning about waterflooding performance

为保障科学合理地开发油田,有必要建立油田水驱开发动态系统预警管理机制,以便决策者及时调整开发策略。建立预警管理机制的基础是构建科学和可操作的预警指标体系。为此,采用新的、适用的理论与方法对油田水驱开发动态系统进行系统分析,确定油田水驱开发动态系统信息表征的指标体系,提出构建油田水驱开发动态系统预警指标体系的原则,通过定性分析确定含21项指标的初选指标体系。确定的指标体系既对评价油田开发水平、开发效果有较高的参考价值,又是油田水驱开发动态系统预警的基础。

Early warning system is necessary in surveillance of waterflooding performance for decision-makers to adjust the development strategy in time.The basis of early warning system is the establishment of a scientific and operational indicator system.The performance of waterflooding is systematically analyzed by using new and adaptable theory and methods.The indicator system of the characterization of waterflooding performance is established.The guideline of the indicator system is put forward.A primary indicator system containing 21 indices is determined through qualitative analysis.This indicator system has a reference value to evaluating oilfield development level and result.
