摘要(Abstract)：

针对气藏的生产特征,基于稳定渗流理论,以气体高速非达西渗流为基础,考虑真实气体PVT参数动态变化,结合气藏物质平衡方程,推导建立同时考虑滑脱效应、启动压力梯度、应力敏感等因素共同影响的低渗气藏动态预测模型,分析各因素对气井产量变化的影响.结果表明:在考虑高速非达西流的基础上,考虑滑脱效应将导致渗流阻力降低而引起气井稳产年限增加和地层压力下降变快,考虑启动压力梯度和应力敏感效应时将导致渗流阻力增加而引起气井稳产年限降低和地层压力下降变慢;启动压力梯度和渗透率变形系数越大,气井稳产年限下降幅度越大,地层压力下降越慢,而滑脱因子越大,气井稳产年限增加幅度越大,地层压力下降越快.
