摘　　要：提高压裂裂缝导流能力是改善压裂效果的重要方面。根据Q241断块储层高孔、中渗、中等偏强水敏、支撑剂嵌入较为严重及地层出砂等特点,指出了Q241断块压裂改造的重点应该是提高裂缝导流能力。从提高裂缝导流能力、降低导流能力的伤害及保持裂缝导流能力等方面入手,系统分析了目前国内外实现高导流能力的一些典型压裂技术措施,确定了适合Q241断块的压裂技术。现场实施3口井,取得了明显的增产效果。Improving induced fracture conductivity is a key way to enhance postfracture response. Based on the characteristics of high porosity, medium permeability, medium to strong water sensitivity, serious proppant embedding and sand producing in Block Q241, improving induced fracture conductivity is put forward during fracturing stimulation of Block Q241. Through the systematic analysis of typical fracturing cases at home and abroad for improving fracture conductivity from the respects of improving and maintaining fracture conductivity and decreasing fracture damage, the fracturing technology suitable for Block Q241 is determined. Furthermore, the stimulation effect of three wells is remarkable in this block.
