将鄂尔多斯盆地二叠系大量试气资料和静态测井资料相结合,通过一元线性回归分析不同测井参数与无阻流量的相关性关系,筛选出孔隙度、渗透率、有效厚度和储容系数4个与无阻流量相关性较好的参数,并在此基础上利用多元线性回归方法得到计算气井无阻流量的新经验公式。通过实例分析验证,该方法结果合理可靠,为致密砂岩气开发中无阻流量预测提供科学的依据。
A large amount of gas test data and static log data from Permian in the Ordos Basin are combined to analyze the correlation between different logging parameters and unobstructed flow through the single linear regression, and the porosity, permeability, effective thickness and storage coefficient 4 A good correlation with the unobstructed flow rate, and based on this, a new empirical formula for calculating unimpeded flow in the gas well is obtained by using the multiple linear regression method. Through the example analysis and verification, the result of the method is reasonable and reliable, which provides a scientific basis for predicting the unobstructed flow in the development of tight sandstone gas.
