介绍了现代电缆地层测试分析系统的原理,用实例叙述了半球形模型、水平裂缝模型、垂直裂缝线性模型和垂直裂缝双线性模型的特征,用压力拟合图显示本方法系统分析的功能。与DPLOT软件相比,本软件考虑了表皮效应、管线存储效应和外边界效应的影响,计算的水有效渗透率较准确,增加了计算表皮系数、管线存储系数和测试半径等测试参数,并给出储层上下界面封闭性质。
The principle of modern cable formation testing and analysis system is introduced. The characteristics of hemispherical model, horizontal crack model, vertical crack linear model and vertical crack bilinear model are described by examples. The function of system analysis by this method is shown with pressure fitting diagram. Compared with DPLOT software, the software considers the effects of skin effect, pipeline storage effect and outer boundary effect. The calculated effective permeability of water is more accurate, and the testing parameters such as the calculation of skin coefficient, pipeline storage coefficient and test radius are added, Upper and lower closure of reservoir properties.
