本文以冷东-雷家地区沙一、二段和沙三段重质稠油油藏为例,在综合研究流体物理性质及地球化学特征、流体性质分布模式基础上,以计算机为手段,采用克里格方法,建立了流体分布三维地质模型,并总结了建立模型的一整套技术方法。

With the development of the theory on oil reservoir description, the studies on the distribution of fluid properties and geochemical models have become an important part of reservoir description. In this paper, the case studies were taken from the heavy viscous oil pools in the 1,2,3 sections of the Shahejia Fr. in the Lengdong-Leijia Region. Furthermore, the authors established a 3-D geochemical model with a computer by using Kriging technology on the basis of comprehensive analysis on physical and geochemical properties of fluid and the distribution model of fluid properties. Finally, a complete set of techniques for establishing a geochemical model was summarized in the paper.
