摘要
为了摆脱分析解释水力压裂裂缝参数时选择图版的繁复工作和克服人为的误差 ,在引入非达西因子的基础上 ,考虑裂缝导流能力在生产过程中的变化 ,提出了垂直裂缝气井中真实气体在地层_裂缝系统中非达西渗流的数学模型和生产动态预测模型 ,建立了识别垂直裂缝气井水力裂缝参数的生产历史自动拟合模型 ,并给出了数值解法 ,为认识和了解气层、分析和评估气井压裂施工质量 ,提供了准确可靠的方法·
In order to devoid the hard work and factitious error in selecting charts while analyzing and interpreting hydraulic fracturing fracture parameters, on the basis of the non_Darcy flow factor, this paper put out the non_Darcy flow mathematical model of real gas in the formation and fracture, established the prodution history automatic matching model to identify fracture parameters, and offered the numerical solutions of those models, which took the variation of fracture conductivity in production process. These results offered a precise and reliable method to understand formation, analyze and evaluate the fracturing treatment quality of gas well.
