摘　　要：针对户部寨气藏低渗、低应力、气水关系复杂、微裂缝发育等特点 ,研究出适合该区的压裂增产技术 ,包括降低压裂液粘度 ,减少压裂前置液用量并加粉砂 ,强制闭合 ,优选井层和制定区块整体压裂方案等技术 ,使压裂增产幅度明显加大 ,有效期增长 。For Hubuzai gas reservoir has the features of low permeability,low stress,complex gas water relation and much microfracture etc.,the fracturing stimulation suited for the area is studied.It includes reducing fracturing fluid viscosity, decreasing the consumption of fracturing preflush and adding flour sand,forced closure,optimum selection layer,and setting integral fracturing program etc.technology.At the same time,the fracturing stimulation make the production increase by a wide margin and provide basis for akin gas reservoir development.
