摘要
文中将常规油气田研究中的油藏工程方法应用于煤层气研究 ,使用物质平衡法建立了煤层气井产能预测模型 ,并且将油藏工程方法和数值计算方法相结合 ,得到了各计算参数之间的关系式 ,使模型在计算机上得以实现。该模型可以计算出产量、压力、采收率等生产数据 ,实现生产预测的目的 ;
Regular oil reservoir engineering method is applied to study coalbed.The model of coalbed gas well productivity forecast is established by using material balance method.Meanwhile,for reservoir engineering method combines with numerical calculation method,the relational expressions of all kinds of calculation parameter are obtained.The model can calculate production,pressure and recovery factor etc.and realize the aim of productivity forecast.Influence law of the model on production status can be explored on the basis of the change of identical parameter magnitude.
