摘　　要：千米桥潜山凝析气藏的储层是由碳酸盐岩组成的。采用酸化压裂增加气井产能的方法已成为千米桥潜山凝析气藏所有探井和开发井的必要措施。通过不稳定试井测试对酸化压裂效果的分析证明:并非所有地层都不具备高产能力;对一些原来渗透性小而没有伤害的地层进行酸化压裂也能取得一定的效果,但是对生产井产能的提高作用是很有限的;地层伤害是影响酸化压裂效果的主要因素。Qianmiqiao buried hill condensated gas reservoir is consists of the carbonate rock. Enhancing gas well producibility by acided-fracturing is the necessary measure of all Qianmiqiao bruied hill condensate gas reservoir prospect and exploitation well. The analysis of the acided-fracturing effect by the transient well test prove to be not all the reservoir that has not the high producibility, the reservoir damage is the dominating factor of the affecting acided-fracturing effect, and that the acided-fracturing of the partial inherent low permeability no damage stratum can acquired the definite effects,but the action has a limited roll on the increase of the well producibility.
