%X Low-permeability reservoir has been paid more attention to in exploration and development as conventional reserve decreases, while economical development and management for low\|permeability reservoir are severely restricted by stress-sensitivity. A summary about previous on stress-sensitivity was made from evaluation method, fluid-solid coupling model and deliverability equation. It is indicated through analyzing that method based on in-situ stress compound with multinomial equation has a desirable accuracy in stress-sensitivity assessment; Development of numerical simulation softwares with regard to fluid-solid coupling and deliverability equation and water injectivity prediction will be the research priorities in this field. It is also pointed out that in no way can stress-sensitive mechanism be revealed merely based on phenomenology or theoretical derivation. It's proposed that a comprehensive evaluation system should be obtained taking into account experimental data, theoretical formula and reservoir characteristic; Establishing appropriate structural model of fracture plane and computer simulation method considering interaction between fracture network comprised of natural and hydraulic fractures is the choke point for fracture stress-sensitivity yet to be broken.
