Acid fracturing is generally applied in carbonate reservoir. It is believed that sandstone reservoir generally uses hydraulic fracturing, and acid-washing or matrix acidizing when removing the plug near wellbore. But whither sandstone reservoir can be stimulated with acid fracturing or not causes people's great concern in recent years. Some oilfield has succeeded when trying by acid fracturing in sandstone reservoir. The paper analyses the reasons that sandstone reservoir can't apply acid fracturing to stim...
