| description | The invention relates to a method and a device for predicting the capacity of a fissure-hole type oil deposit. The method includes the steps of acquiring oil deposit bubble point pressure Pb, a volumetric factor B, in-place oil viscosity mu, the shaft radius rw, the oil reservoir thickness h, matrix permeability Km, fissure permeability Kf, oil deposit supply boundary pressure Pe, the boundary radius re, shaft bottom flow pressure Pw, a matrix permeability damage factor alpha m, a double-medium reservoir permeability damage factor alpha A and fissure closing pressure Pf. Fissure-hole type double-medium reservoir permeability KA is obtained according to the matrix permeability Km and the fissure permeability Kf; on the basis of permeation fluid mechanics, the stratum fissure closed radius rf is obtained by the acquired parameters; on the basis of inner and outer boundary conditions and reservoir permeability stress sensitive effects, the relation between the capacity of the fissure-hole type oil deposit and sh |
