摘要
低渗透气藏都需要增产改造来获得增产,使用聚合物进行高砂比施工,目的是为了获得导流能力较高、支撑较长的裂缝。尽管冻胶液携砂能力很强,但是存在地层伤害,返排等问题,且成本很高。文章探讨了页岩气清水压裂技术。
The low permeability gas reservoir needs production stimulation for production,using polymer in than construction in order to obtain higher diverting capacity,support long cracks. Although gel liquid carrying capacity is very strong,the existence of formation damage,flowback problem,the cost is very high. Shale gas water fracturing stimulation technology was discussed in the article.
