Nano Fracturing Technology of Coalbed Methane Wells for Low cost industrial production

摘要：

　　The key factors for CBM reservoir adsorption gas desorption rate are pore radius、saturated gas content、Network size seam fracturing of communication and expand nanometer pore and seam、gel breaking in time、fracturing fluid residue can be Timely flowed back、continuous drainage gas recovery in a timely manner、group well for a long time constant drainage、often remove of the pulverized coal clogging.First,in nanometer center well fracturing,using the Dissolving and the corrosion,Communication cracks and expand the throat,enlarge the nanometer pore and seam,communication native hole seam,carrier and Made seam,formed Cracks network, improve the desorption speed,improve the seepage velocity.Second,timely flowback.Third,continuous drainage and Gas recovery.Fourth,all Wells of the development area can be fractured with nano fracturing.Fifth,dissolve Pulverized coal and flowback pulverized coal in a timely manner,In the whole production process.Low cost industrial production of coalbed methane will inevitably lead to low cost industrial production of shale gas,other adsorption gas,adsorption oil,ultra dense and low permeability oil and gas.
