intercept-gradient截距-梯度
1.The paper first reviewed the P-P wave AVO response feature and its classification,then systematically expounded the P-SV wave AVO response feature from P-SV wave reflection coefficients and amplitude feature,normalized P-SV wave reflection coefficients and intercept-gradient feature and relationship between the variation trends of strata parameters and AVO types.本文首先回顾了P-P波AVO响应特征及其分类,随后从P-SV波反射系数及振幅特征、归一化的P-SV波反射系数及截距-梯度特征、地层参数变化趋势与AVO类型的关系等方面系统地阐述了P-SV波AVO响应特征。

1.Four properties, such as lithology, electric property, physical property and oil-bearing property and their inherent relations are studied, the model for logging data processing and interpretation are established, a crossplot of 4 properties is made, by which a criterion for quantitative interpretation of oil, water and dr.通过研究取心井储层岩性、电性、物性及含油性及之间的内在关系,拟合了相关性较好的测井资料处理解释模型;并做出了试油资料与相应储层岩性、物性及电性等参数的交汇图,得到了油、水、干层的定量解释标准,从而为实现储层参数由取心井到非取心井的定量求取,为进行测井资料二次数字处理提供了可靠的基础。

梯度分子式:CAS号:性质:设体系中某处的物理参数(如温度、速度、浓度等)为w,在与其垂直距离的dy处该参数为w+dw,则称为该物理参数的梯度,也即该物理参数的变化率。如果参数为速度、浓度或温度,则分别称为速度梯度、浓度梯度或温度梯度。
