摘要
三塘湖盆地牛东区块上石炭统卡拉岗组(C_2k)火山岩储层与其他火山岩储层一样,具有强水敏和低温的特点。并且,该类储层在压裂时容易发生高滤失及高砂堵等现象。为了在压裂改造时对天然裂缝实施保护和对人造裂缝进行控制,通过研制新的压裂液添加剂、并结合必要的工艺参数优化及施工工艺的调整,保障了高砂比及低温低伤害压裂的需要,现场应用取得了显著的增产效果。
Similar to other domestic volcanic reservoirs, the volcanic reservoir of Carboniferous Kalagang （C2k） formation in block Niudong in Santanghu basin is characterized by strong water sensitiveness and low temperature. Moreover, high filtration and high sand plug take place during fracturing of the reservoir. In order to protect natural fracture and control artificial fracture during fracturing, a new fracturing fluid additive is developed, combined the optimization of technology parameters and adjustment of operation technology, the need for high proppant concentration and low temperature and low damage fracturing is ensured. Notable stimulation effect is obtained in filed application.
