| 摘 要： | 在渗流力学基础上建立了考虑应力敏感性的三维气、水两相流数值模型，编写了相应的数值模拟软件。在此基础上进行的模拟计算表明，应力敏感性对气井稳产能力具有显著影响，可导致气井所需生产压差明显增大，在应力敏感情况下进行开采，气井对地层能量的利用率将会大大降低。而异常高压气藏由于原始地层压力高，有效应力变化范围大且下限低，储层岩石具有更强的应力敏感性。因此。在进行异常高压、低渗气藏开发的生产动态预测时应充分考虑储层应力敏感性的影响，使编制的开发方案能更加准确地指导该类气藏的开发。

| Abstract: | Based on the seepage flow theories, a numerical model was established for dealing with three-dimensional gas-water flow to take the stress sensitivity into account, and also program a relevant numerical simulation software. The result of numerical simulation shows that the stress sensitivity has great impact on gas well productivity, results in higher drawdown pressure needed by gas wells. Meanwhile, during the exploitation with stress sensitivity, the efficiency of formation energy for the gas wells decrea... |
