发明名称 Underground treatment of biowaste
摘要 A method of disposal of biowaste material which comprises drilling a first section of an injection well from the ground into a porous layer, drilling a second section of the injection well from a lower terminus of the first section of the injection well into the porous layer while drilling the same using underbalanced drilling techniques, drilling a first section of a production well from the ground to and into the porous layer, drilling a second section of the production well from the lower end of the first section thereof into the porous layer using underbalanced drilling conditions, making a geological measurement of the pore throat size and/or fracture aperture in the porous layer and treating the biowaste material introduced into the second section of the injection well by comminuting the same in a device such as a shear pump to an average particle size of approximately one-tenth to one-half, preferably one-seventh, of the average pore throat size in the porous layer, the measurement of the pore throat size and/or fracture aperture of the porous layer and the comminuting of the biowaste material being completed prior to the introduction of the biowaste material into the injection well.
