摘要
针对气藏开采过程中气体在井筒内流动的特点,根据Turner模型推导了井筒内临界携液流量公式,然后又根据井筒临界携液流量公式,计算并说明了井口压力和气体流动速度之间的关系,并为了便于现场使用,导出了临界流量和产量的计算公式。
In view of the characteristic of the gas which flows in the wellbore during the process of gas fields exploitation and according to the Turner model, we inferred the eritial liquid carrying flow rate formula which in the wellbore, and then calculated and explained the relationship between the wellhead pressure and the critical velocity, and in order to facilitate the field using, we have derived the formula of the critical flow rate and output.
