基于老井测井资料和孔隙结构参数的产能预测

Forecast of Production Capacity Based on Log Data and Pore Structures from Old Wells

以华北油田饶阳凹陷蠡县斜坡外带沙一下段为研究对象,在岩心和测井资料分析的基础上,采用统计分析方法,分析孔喉半径参数与储层渗透能力的相关性,确定影响储层物性的主控因素,研究孔隙结构参数对储层产能的影响及其规律。在此基础上,深度挖潜老区测井资料,建立基于老区测井资料的孔隙结构表征参数模型,构建储层产能预测模型,应用于老区潜力层评价,激活一批老井,为该区域中深层滚动开发提供依据,增储上产效果明显。

Taking the ES1 in the outer zone of the Lixian slope in the Raoyang sag as a case,this paper analyzes the relation between the radius of pore throat and reservoir permeability using a statistical method on the basis of core and logging data,determines the controlling factors on the reservoir physical properties,and studies how pore structures affect the reservoir productivity and flow which rules,then establishes pore structure characterization models based on log data from old wells,and finally capacity forecast models.Used to evaluate the potential of old exploration areas,the method has activated some old wells.It provides the basic data for deep and rolling development and can increase production and reserves in the study area.
