| 摘 要： | 我国存在大量的低渗透气田，由于自然产能低，需要进行压裂后才能生产。如果压裂后配产不合理，将导致出砂、裂缝闭合、气井出水等不利情况。为此，根据低渗透气藏需要进行压裂生产的特点，运用质点动力学的方法，建立裂缝中存在压裂砂情况下的临界气流速度公式。研究了保持压裂裂缝导流能力的最大生产产量的确定方法，为矿场的合理生产奠定基础。 |
| 关 键 词： | 低渗气藏 压裂生产 合理产量 最大生产量 极限产量 |

| Abstract: | There are a lot of low permeability gas fields in our country. For their low natural deliverability,they need to be fractured to get industrial gas flow.Improper post-frac production allocation will result in sanding,fracture closing and water breakthrough.Based on the fact that low permeability gas reservoir needs fracturing,particle dynamics is used to establish critical gas flow velocity equation when there is fracturing sand in fractures.The determination method of maximum production is studied which could maintain fracture deliverability. |
| Keywords: | low permeability gas reservoir fracturing rational deliverability maximum production limit production |
