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。
Abstract
There a re a lo t o f low perm eab ility gas fie lds in our country. Because of the ir low natural de liverab ility, they need to be fractured to get industrial gas flow. If production is not set proper ly, fracture w ill c lose and gas w e ll w ill produce w ater, and our purpose of increasing production w ill fai.l This paper bases on the fact tha t low perm eability gas reservo ir needs frac tur ing. By using pa rtic le dynam ics, we estab lish critica l gas speed equation where there is frac tur ing sand in fracture. Then we study the m e thod o f determ ing m ax inum production w hich can m a inta in fracture de liverb ility.
