| 摘 要： | 大厚段砂砾岩储层具有物性差、可动流体饱和度低的特点,压裂是该类储层增产、稳产的重要措施,压后效果的好坏取决于人工裂缝与储层物性的匹配关系.大厚段砂砾岩储层压裂具有支撑缝长与缝高匹配困难;多裂缝发育、压裂液滤失严重,砂堵风险大;存在支撑剂嵌入,裂缝导流能力损失严重.通过技术攻关,形成了使用大排量、高粘度压裂液充分造缝;控... |

| Abstract: | The Most of big and thick glutenite reservoirs had the characteristics of poor physical properties and low movable fluid saturation,therefore fracturing was the key measure for enchancing and stabilizing oil production.the post-fracturing effect depended on the matching of hydraulic fractures and reservoir properties.In big and thick glutenite reservoir fracturing,it was difficult for supporting fracturing length and matching its height;where multiply fractures were developed and fracturing fluid loss was s... |
| Keywords: | big and thick section glutenite reservoir fracturing combined proppant reasonable placment application |
