建立高精度的储层物性参数解释公式,在油田开发工作中具有重要的意义。为此,提出了研制物性解释参数的方法:首先从取心井岩心分析资料出发,结合测井曲线特征,分析岩电关系,确定物性参数解释模型的理论基础,然后对岩心分析、测井资料加以校正。在此基础上,对卫城油田沙三下储层,利用线形回归理论,建立该区孔隙度、渗透率解释公式。经对该解释公式检验,自检误差小,解释精度高,操作简便,在该区使用中取得了较好的效果。

It is very important in development of Oilfield to create explanation formula of reservoir bed physical characteristics. Therefore , this paper providedthe development way of physical character explanatory parameters : at first , from core analysis data start , combine logging curve characteristics analysis of rock and electricity , determine theory basis of physical characteristics explanation model ; Secondly , correct core analysis date and logging data. On this basis , for the lower Es3 reservoir of Weicheng Oilfield , making use of linear regression theory create this region’s explanation formula of permeability and porosity. Test this explanation formula , error is low , explanation precision is high , operation is handy , and obtain better result in this region.
