摘　　要：白马庙气田蓬莱镇气藏属致密砂岩气藏,于1997年5月投入试采。气井原始产能低,多数气井如果不进行储层改造则无工业性气流。迄今为止气藏共有29井次进行了储层压裂改造,压裂有效20井次。文中从压裂施工曲线拟合、试井资料解释及气井生产效果等方面对气井压裂效果进行了综合分析,对影响气井压裂效果的因素进行了较深入的研究,对该气藏下一步储层改造工作有重要的指导意义。Penglaizhen Gas Pool of BaiMamiao Gasfield,which belongs to tight sandstone gas reservoir, was put into production in May, 1997. The initial productivity of gas wells in this gas field were low. In fact, there shouldn' t have had commercial gas out from most of them without any stimulation measurement. So far,29 wells in this gas field have been fractured, 20 of which have been improved. According to the fracturing operation plots, well test interpretation results and gas production data, we analyzed in detail the key factors that influenced the outcome of fracturing. It has important practical significance to guide the reservoir fracturing in the near future.
