综合利用地震、钻井、测井及开发动态等资料，研究了塔里木盆地塔中西部地区高效井与串珠状地震相储层的关系。提出了峰谷能量指数的概念，指数越大，串珠状地震相储层越发育。若强串珠状地震相发育伴生断裂，则储层发育规模较大；串珠状地震相位于缝洞系统的相对高部位，则一般油柱高度大，有较长的无水采油期。对于强串珠状地震相，水平井水平段轨迹设计在最大波谷处较为合适；对于弱串珠状地震相，水平井水平段轨迹设计在最大波谷之下的零相位之上较为合适。塔中西部实际应用结果表明，具备四项要素(峰谷能量指数大于17000、伴生断裂发育、处于缝洞体系高部位、目的层井轨迹位于储层顶部)的强串珠状地震相储层，钻井易高产稳产。

According to seismic, well logging and production data, the relationship between moniliform seismic-facies Ordovician carbonate reservoirs and efficient wells is studied in the west of Tazhong Uplift, Tarim Basin. It is proved that carbonate reservoirs mostly develop in those strong seismic-facies beads that is characterized by the basic factors:(1) peak to trough amplitude index more than 17000, (2) developing associated faults, (3) in relatively high locations of fractured-vuggy system, and (4) the well trajectory of target zone at the tops of reservoirs. These are the important pre-requisites for keeping long period of high and stable yield.
