摘　　要：气藏产量和可采储量的预测,是气藏工程计算中的一项重要内容。油气田开发指标预测的准确性和可靠性,将影响编制中长期开发规划的效果,对于指导气田方案编制具有重要的参考意义。目前,峰值预测模型已广泛应用于油气田产量发展趋势预测,但研究内容大都限于模型的建立,参数选取和求解,对于模型中影响参数的实际物理因素研究不足。本文通过建立油藏数值基理模型,对得到的不同采气速度下的年产量曲线用各个模型预测法进行拟合,建立起模型参数与采气速度之间的联系,更好地指导气田规划方案和开发。The prediction of gas reservoir production and recoverable reserves is an important part of gas reservoir engineering calculation.The accuracy and reliability of oil and gas field development index prediction will affect the preparation of medium and long-term development planning,and it has important reference significance for guiding gasfield planning.At present,the peak prediction model has been widely used in oil and gasfield production development trend prediction.But the research content is mostly limited to the establishment of the model,parameter selection and solution,and the actual physical factors affecting the parameters in the model are insufficiently studied.In this paper,by establishing the reservoir numerical basis model,the annual production curve under different gas recovery rate is fitted with each model prediction method.And the relationship between model parameters and gas production speed is established to better guide the gasfield planning scheme and development.
