【摘要】 为了保证在油田三次采油过程中,新的油田目标区块能够优选出最佳的采油驱替方式,以国内外典型区块三次采油驱替方式矿场应用作为基础,统计分析得到23项油藏参数作为影响采油驱替方式优选的关键参数,并通过模糊评判方法优选出目标区块合适的驱替方式。通过改进的邓氏关联法计算得到目标区块与实例应用区块的关联度,进而预测目标区块采收率,根据预测的采收率来选取最佳的驱替方式。最后,选取国内某油田的新区块作为研究实例,优选得到最佳驱替方式是火烧油层驱替方式,提出的方法为新区块的驱替方式优选提供了计算依据。更多还原

【Abstract】 In order to ensure that the best oil recovery and displacement method of the new target block of the oilfield could be selected in the process of tertiary oil recovery, based on the application of tertiary oil displacement method in typical blocks at home and abroad, 23 reservoir parameters have been studied as the key parameters that affect the displacement mode, and the fuzzy evaluation method are used in the process. And then, the correlation between the target area and the test area is calculated by the improved Deng’s correlation method, so as to predict the recovery ratio of the target area. The study of a new block of some oilfield in China verify that the best displacement mode is fire flooding. The proposed proposed method provides a calculation basis for the optimal displacement method of the new block.更多还原
