摘　　要：井间动态连通性反映了流体在井间的流动能力好坏,是油(气)藏工程评价的重要参数。从渗流力学的角度出发,结合灰色理论,推导和验证了灰色关联度计算井间连通性的可行性;应用渤海油田某油藏的生产动态资料,利用灰色关联度方法,计算注、采井间动态数据的相关性,通过其相关性大小定量评判了井间连通程度的强弱和水驱油效果的好坏。结果表明,灰色关联度能有效评价井间连通性,并对水驱效果评价工作具有重要的参考价值。The interwell dynamic connectivity reflects the flowability of fluid between wells,which is the important parameter for oil(gas)reservoir engineering evaluation.From the aspect of fluid mechanics and combined with grey theory,the feasibility of calculating the interwell connectivity with the grey theory is derived and proven.The production performance data of Bohai Oilfield and grey correlation method are used to calculate the correlation of production performance data between injection and production wells.Through the correlation scale,the strong or weak interwell connectivity and water flooding effect are quantitatively evaluated.The result shows that the grey correlation method can be used for effectively evaluating the interwell connectivity,it also provides an important reference for evaluating the waterflooding effect.
