Stimulation Technology For Intermediate And Basic Volcanic Reservoir

It has been deep analysised in this text ,Aiming at the problem that low production fractured well of the deep-zone intermediate and basic volcanic reservoir, the main factor of poor stimulation effect, including low active fluid saturation, low pore connectivity is determined. The mechanism of substantially increasing effect contact area between fracture and formation, diagnosis plate of physical property has been build up to classify the formation into three type, which provide basis for selecting zone in fracturing well. This research developed stimulation technology for different type formation to meet the stimulation need, increasing operational scale for type formation, and mix-riverfrac treatment and sidetrack horizontal well drilling technology. All of four wells site tested meet the commercial gas flow.
