摘　　要：采用将动态与静态数据相结合 ,从 6个方面研究井间地层连通性的综合分析方法。该方法考虑的 6个方面为 :地层各处原始折算压力近似相等 ;各井原始地层压力与深度成线性关系 ;在开采期间 ,各井地层压力同步下降 ;各井产量递减总体趋势类似 ;某井工作制度发生变化时 ,邻近井有干扰反映 ;各井原油密度、组份等一致。采用此方法 ,对TH油田进行了实例分析。结果表明 :该方法得出的认识可靠 ,它对于复杂多重介质中井间地层连通性的确定尤为重要。An aggregate analysis method that combines static data with shifting data based on six different respects is used to determine continuity of formation between wells.The respects include the following:conversion original pressure of the formation is almost constant everywhere;relationship between the pressure and depth is linear;pressure of each well drops at the same step during the producing;tendency of an output decreases of one well is similar to another;when working condition of one well changes,other wells close to the well occur interference;and density and composition of oil from each well is almost constant.An example of TH Oilfield is discussed dy the method.Results show that cognition by the method is reliable.It is very important that continuity of multiple porosity/permeability formation between wells be determined by the method.
