摘要: 在试井资料解释中典型曲线是一个很有用的工具。一旦得到最佳拟合,拟合点和拟合曲线数据可以用于计算地层流动系数(Kh/μo)和地层有效渗透率(K),以及井筒储集常数(C)和表皮系数(S)。但是,它不能用于确定地层压力。在本文中,提供了一个利用典型曲线拟合数据,确定地层压力的方法。因此,扩大了典型曲线的应用范围。

Abstract: Type Curve is a very useful tool in the interpretation of Well test data. Once the optimum match is obtained, the match point and the match curve data, may be used to Calculate formation transmissibility (Kh/μo) and formation effective permeability (K), along With Wellbore storage Constant (C) and skin factor (S), but it Can not be used to determine reservoir pressure in the past. In this paper, a method of determining reservoir pressure by match data of the type Curve is presented. Therefore, the application range of the type Curve Will be extended.
