摘　　要：我国有大量低渗透气田,这类气藏自然产能极低,需要压裂后才能进行生产,若压裂后配产不合理,将导致出砂、裂缝闭合等不利情况,达不到增产的目的。根据低渗透气藏的这一特点,运用质点动力学方法,建立裂缝中存在压裂砂情况下的临界气流速度公式,研究保持压裂裂缝导流能力的最大生产产量的确定方法,为矿场合理生产奠定基础。There are a lot of low permeability gas fields in our country.Because of their low natural deliverability,they need to be fractured to get industrial gas flow.If production is not set properly,fracture will close and gas well will produce water,and our purpose of increasing production will fail.This paper bases on the fact that low permeability gas reservoir needs fracturing.By using particle dynamics,we establish critical gas speed equation where there is fracturing sand in fracture.Then we study the method of determing maxinum production which can maintain fracture deliverbility.
