洪积扇砾岩储层非均质性及非均质模型

HETEROGENEITY AND HETEROGENEITY MODELS OF PLUVIAL CONGLOMERATE RESERVOIRS

应用地质统计学方法,以计算机模拟技术为手段,全面系统地研究了克拉玛依油田洪积砾岩储层的非均质特点,在描述砾岩储层高渗透层段性质、分布的基础上建立了高渗透网络的随机剖面模型。阐述了影响砾岩油藏注水开发效果的高渗透结构与构造,进而划分出四类砾岩储层并建立了相应的非均质模型。

Applying geological statistics, heterogeneity of pluvial conglomerate reservoirs in the Karamay oilfield was tho-roughly and systematically studied with the help of computer modelling. Based on describing the properties and distri-bution of the high permeability intervals in the conglomerate reservoirs, we established random section model of thehigh permeability network. illustrated the high permeability textures and structures influencing the effect of floodingdevelopment of the conglomerate reservoirs, divided four kinds of conglomerate reservoirs, and established the corres-ponding heterogeneity models.
