序贯指示建模方法在枣南油田储层非均质研究中的应用

我国陆相注水开发油田油藏描述的关键之一是如何建立反映储层非均性的储层地质模型.在枣园油田的油藏描述中,应用地质统计学的序贯指示随机建模技术对枣南Ek~2油组的渗透率进行了研究,研究结果表明序贯指示建模方法不仅比常用的插值方法更能反映储层参数的变化,而且能够描述由于资料的缺乏而引起的模型的不确定性.

RESERVOIR HETEROGENEITY STUDY OF ZAONAN OIL FIELD BY A SEQUENTIAL INDICATOR SIMULATION APPROACH

Reservoir heterogeneity is one of the critical problems in reservoir characterization,espceially in waterflooded oil fields in the east part of China.In order to provide a reliable and precise reservoir model to the reservoir engineers,Sequential Indicator Simulation is used tomodel the distribution of reservoir properties in Zaoyuan oil field.Results show that Sequential Indicator Methods have many advantages over traditional introplation methods and themodels estahlished can not only reflect the reservor heterogeneity,but also can predict un-certainty due to lack of geological information.
