发明名称 | Stimulation method | ||
摘要 | A stimulation method involves arranging a fluid-activated gun in a well through a well head and/or a blowout preventer, dividing the well into a first and a second part, the first part being closer to the well head and/or blowout preventer than the second part, pressurizing the first part of the well with a hot fluid, the hot fluid having a temperature which is higher than the temperature of the formation at a downhole point of injection, activating the fluid-activated gun, thereby converting energy from the pressurized hot fluid into mechanical waves, directing said mechanical waves into the formation, and injecting the hot fluid into the formation simultaneous to activation of the fluid-activated gun via the hot fluid. | ||

主权项 | 1. A stimulation method comprising the steps of: arranging a fluid-activated gun in a well through a well head and/or a blowout preventer, dividing the well into a first and a second part, the first part being closer to the well head and/or blowout preventer than the second part; pressurising the first part of the well with a hot fluid, the hot fluid having a temperature which is higher than that of the formation at a downhole point of injection; activating the fluid-activated gun, thereby converting energy from the pressurised hot fluid into mechanical waves; directing said mechanical waves into the formation; and injecting the hot fluid into the formation simultaneous to activation of the fluid-activated gun by means of the hot fluid. | ||
