摘要
Abstract
The large-scale fracturing of deep reservoirs in Hailar Oilfield has high cut-off pressure gradi-ent,difficult sand addition and low fracturing benefit.In order to clarify the characteristics of fracture initia-tion and expansion in reservoirs with high pump stopping pressure,and optimize fracturing operation param-eters,FracproPT software is used to simulate the crack propagation of high shutdown pump reservoirs in Hailar Oilfield.The characteristics of fracture initiation and propagation law are analyzed.The influences of permeability,stress difference between reservoir and interlayer,Young's modulus and Poisson's ratio on fracturing operation parameters are analyzed.The results show that the fracture height is easy to lose con-trol,the fracture length and sand concentration are small,and the construction success rate is low.Accord-ing to the characteristics of fracturing construction in reservoirs with high pump stopping pressure,the opti-mal design method is finally formed,which controls pressure and limits fracture height.The method has been confirmed through example wells,which provides a good reference for fracturing design and efficient development of fracturing in reservoirs with high pump stopping pressure.关键词
