| 摘 要： | 在凝析气藏衰竭开采过程中,凝析油会在井底附近析出并逐渐积累形成高饱和度区域,造成气相渗透率和绝对渗透率降低,影响凝析气井产能;因而,凝析气井产能方程的确定有很大困难.提出将凝析油气两相指数式方程中的拟压力积分分解为两个积分函数之积,一个积分函数与流体高压物性有关,另一个积分函数与流体的有效渗透率有关.在此基础上,又提出了用实际凝析气井不稳定压力试井数据来确定所定义的拟有效渗透率,从而可确定凝析气井产能方程中的真实拟压力,由此获得实际凝析气井产能方程.

| Abstract: | Under the production of the gas condensate depletion, condensate oil began to buildup at the bottomhole and gradually formed the high saturated region, led to the relative permeability and absolute permeability dropping, and the productivity of the gas condensate was influenced. The pseudopressure product in the equation of two phase fluid index of the oil and gas condensate was divided into the product of the two integral functions, one product function related to the physics properties of the high pressure, the other production function related to the effective permeability. Based on the study of the paper, the pseudo-effective permeability with the transient pressure determined with test well data was presented, and obtained the real pseudopressure and IPR for the gas condensate well. |
