摘要：According to the core problem of the oil-gas reservoir fracturing crack formation, this paper proposes that the essence of the oil-gas reservoir fracturing crack formation is the deformation energy accumulation increase and suddenly release of the rock mass which is resulted by fracturing pump work. Based on the principle of conservation of energy, the reservoir fracturing rock mass damage folding mutation model is established. The standard form of balance equation and energy release about the reservoir fracturing rock mass mutating is given. Combined with the actual fracturing of a block of Daqing Oilfield, the energy release quantity is calculated and the calculated result is reasonable which provides a new method for the study of the hydraulic fracturing crack parameters.
