复杂断块油藏构造建模及应用

Structure Modeling of Complicated Fault-block Reservoir and Its Application

以地震、测井解释成果、小层对比的井点数据,先断面骨架模型再断层网格模型,进而以井点分层数据及断层属性数据实现复杂断块油藏构造模型的建立。复杂断块油藏与常规油藏最大的不同在于油藏被断层复杂化,因此复杂断块地质建模关在于建立较精准的断层及构造模型,只有这样才能形成储层物性参数赖以分布的地质模型,才能为油藏数值模拟提供较为实际的数据场。本文使用与此思路相适应的Petrel软件实现了某断块储层的精准构造模型的建立,取得了良好的效果。

The well point data from the seismic exploration result,logging interpretation result and sub layer contrast can be used to simulate the fractured surface model and fault grid model,then the well point hierarchical data and fault property data can be used to simulate the structural model of complicated fault-block reservoir.The most difference between complicated fault-block reservoir and conventional reservoir is that reservoir was complicated by the fault,so the key of the structural model of complicated fault-block reservoir lies in the accurate fault and structure model,only in this way can we form the geological model which providing the basis for distribution of the reservoir physical parameter and the practical data set for reservoir numerical simulation.In this paper,the Petrel software which is adapting the author's thought was used to realize a precise structure model of a fault block reservoir,and good effect was achieved.
