摘要
针对异常高压气藏开发实践,利用气体稳定渗流理论,推导得到考虑异常高压气藏应力敏感性的产能方程,并对某异常高压气藏实例井的产能进行了预测,预测效果较好。本次研究提出的产能方程符合异常高压气藏的开发实际,具有重要的指导意义。
A deliverability equation is derived for gas reservoirs with abnormally high pressure with consideration of stress sensitivity based on steady percolation theory. The deliverability of a case well is predicted with the equation and the result is preferable. This deliverability equation conforms to the practical recovery process of gas reservoirs with abnormally high pressure and has a guiding significance.
