摘　　要：火山岩储层压裂增产改造是国内外面临的新课题,没有成熟的工艺模式,风险大、效果差。如何准确把握制约难点和研究实施有针对性的工艺方法,已成为火山岩勘探开发取得突破的关键。针对火山岩储层致密、低孔、低渗、微裂缝发育、自然产能低等特点,建立裂缝启裂与延伸模型,采用快速解释诊断、前置液降滤失和裂缝控制延伸技术,以及压裂液体系优选等工艺处理措施。通过对松辽和三塘湖盆地的现场试验效果应用,压裂成功率、施工规模及单井增产效果均取得明显的提高,推动了火山岩油气藏的勘探开发。Volcanic reservoirs fracturing stimulation technology mature process model, it is difficult to have great risk and bad a targeted is a new facing issue at home and abroad. Without effect. How to grasp the difficulties and implement approach accurately, is a key breakthrough in Volcanic reservoir exploration and exploitation. Consider- ing the characteristics of low - hole, low - permeability, micro - fracture development low natural productivity of reservoirs , this paper introduces five technical measures which contain establishing the model of fracture crack and extend, adopting quick explain diagnosis technology, preflush drop filter and fracture control technology, optimizing the system of fracturing fluid. According to the field application of Songliao and Santanghu basin, fracturing success rate, construction scale and stimulation effect of single well are significantly improved. It also promotes the explora- tion and development of volcanic reservoir.
