It gives out the calculation equations of oil zone parameters by using coring data,testing data and production data,and a method of distinguishing oil zones from water zones by overlapping neutron porosity curve and.
以岩心分析、试油、投产等资料研究为基础,建立了参数解释图版;用中子孔隙度曲线同介电常数、相位角曲线重叠识别油层;用介电测井资料结合常规测井资料综合进行稠油低阻油层解释。

The results indicate that the overlap between density and neutron porosity curves from LWD data is related with reservoir depletion degree and production GOR when the formation pressure is less than the bubble point pressure.
研究不同衰竭程度和生产气油比时LWD体积密度和中子孔隙度测井响应特征发现,当地层压力小于饱和压力时,LWD测井密度和中子孔隙度曲线重叠区的大小与油藏衰竭程度和生产气油比具有一定关系,重叠区越大,地层压力越低,油藏衰竭程度就越严重,生产气油比也越高。
4) density porosity
密度孔隙度
5) Double neutron porosity difference
双中子孔隙度差值
6) macropore density
大孔隙密度
1.
In this paper,we regard that soil is divided into two porous media,one for matrix flow,one for macropore flow,and a macropore is assumed extend vertically from soil surface down to desired depth,macropore density is also imported into model to describe the complex distribution of macropore in soil.
将土壤介质在空间上分为基质区与大孔隙区2种介质区,把大孔隙看作竖直向下的管道,并利用土壤大孔隙密度概念,把杂乱无章的大孔隙分布进行了简化,同时采用不同的方法分别对2种不同介质内的水流进行了模拟,在算例计算时又采用了区域分解算法,提高了计算效率。
补充资料：催化剂孔隙度(degree of catalyst pole)
分子式：
CAS号：
性质：又称催化剂孔隙度(degree of catalyst pole)。多孔性催化剂颗粒内微孔的总体积，单位是ml/g。其大小由催化剂制备条件决定。
