摘　　要：优选适合文23气田的低伤害压裂液,采用综合保护技术,在压裂施工中采用分段破胶、裂缝处理技术和裂缝强制闭合技术,减少了液体对储层的伤害;优化压裂设计施工参数和施工方式,在前置液中加入支撑剂段塞,提高了压裂设计参数的准确性,使文23气田的施工成功率和压裂效果明显增加。That selecting low harmful fracturing fluid available to this field, adopting integrate protective technology, applying subsection break glue, crack treat and crack force close reduces that liquid damage to deposit layer, by improving fracturing design parameter veracity with optimize parameter and mode for fracturing implement, and putting propagent slug into preposition liquid, the veracity of fracture design parameter is increased which raises up the successful ratio of operation in Wen23 gas field and increases fracture positive effect significantly.
