Developing Typical Curve Graph of Reservoir Physical Parameter in Oil Reservoir Description

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 Es 3 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.
