气井的二项式产能方程分析影响气井产能的主要因素包括:地层压力、井底污染、地层渗透率、地层有效厚度、天然气粘度、泄气半径、气井半径,对这些因素的分析是气井产能分析的一个主要内容,同时也是研究预测气井产能预测模型的基础性工作,其研究结果直接影响到预测模型的准确性、可靠性和科学性。 Gas well binomial productivity equation analysis The main factors affecting gas well productivity include: formation pressure, bottom hole contamination, formation permeability, effective formation thickness, natural gas viscosity, deflated radius, gas well radius, and the analysis of these factors is the gas well productivity analysis The main content of this study is also the basic work of the research on forecasting gas well productivity prediction model. The research results have a direct impact on the accuracy, reliability and scientificness of the prediction model.
