区域井群开采降深预测的尝试——以中原油田主要油区为例

Trial of Depth Reduction in Regional Well Group Production——By Taking the Major Oil Region in Zhongyuan Oilfield

介绍了中原油田的水文地质概况及主要油区的分布。将非稳定渗流理论用于中原油田区域干扰井群不间断开采条件下的降深预测,给出了预测步骤。采用该降深预测方法,不仅科学地指导了下泵深度,减少了大量的起下泵工作量,保证了原油上产,同时对调整开采方案、合理开发地下水也具有重要意义。

The hydrogeologic situation and the distribution of major oil region in Zhongyuan Oilfield are introduced.The theory of nonsteady percolation is used for predicting depth reduction for regional interference well group in Zhongyuan Oilfield under the conditions of continuous production,and procedures for prediction are given.The method for depth reduction are not only for guiding pump setting depth scientifically,also reducing a great deal of work for pump tripping and ensuring oil production,and at the same time it is of great significance of adjusting production scheme and rational production of underground water.
