油田水驱开发效果评价与预警模型研究

Research on Oilfield Water Flooding Development Effect Evaluation and Its Pre-warning Model

为确保油田水驱开发的科学与高效发展,建立油田水驱开发效果评价与预警管理机制非常必要。采用层次分析和模糊综合评判对油田水驱开发效果进行综合评价,在综合评价的基础上,设计基于人工神经网络的油田水驱开发效果预警模型,并结合算例对模型进行验证。模型与实际吻合较好。

In order to ensure high-efficient development oilfield water flooding, oilfield water flooding development effect evaluation and pre-warning model is due to be built. Therefore, comprehensive evaluation on water-drive oilfield development effect was implemented by analytic hierarchy process and fuzzy mathematics appraisement. At the same time, artificial neural network was adopted to realize early warning on dynamic system of oilfield development.
