火烧山油田沉积相随机建模研究

针对火烧山油田，在以小层为单位，通过传统的方法作沉积微相研究时，同一小层就可能存在两个以上的沉积微相，这样沉积微相分析特别是按小层为单元的沉积微相分析的准确性就不能保证，同时这样也影响了储层参数建模的准确性.为了解决这一问题，从三维出发，建立沉积微相在三维空间上的分布规律，在更真实的沉积相模型的控制下，才能进一步建立储层参数的三维空间模型.综合考虑，本区相建模采用的是序贯指示模拟方法.

STUDY ON THE RANDOM MODELIZATION OF SEDIMENTARY FACIES IN HUOSHAOSHAN OIL FIELD

In the research of microfacies of Huoshaoshan oil field, it is found that there exist two or three facies in each stratigraphic layer, but only one can be identified by traditional method, which is inexact and influential to the veracity of reservoir parameter modelization. In order to resolve the problem, we establish a facies distribution model in tridimensional space. Controlled by this microfacies, the tridimensional model of parameter is more exact. The sequence indication method for modelization is applied in the area.
