Method and system for determining compressibility of low-permeability tight reservoir and computer equipment

The invention provides a method and system for determining compressibility of a low-permeability tight reservoir and computer equipment. The method specifically comprises the steps that parameter values of factors influencing the volume fracturing compressibility of the tight reservoir are calculated; standardizing the parameter value to obtain a standardized value; carrying out normalization processing on factors influencing the compact reservoir volume fracturing compressibility, establishing a radar map, and forming polygonal areas among the factors; and quantitatively determining the compressibility of the low-permeability tight reservoir according to the size of the polygon area. The compressibility of the low-permeability tight reservoir can be quantitatively evaluated, and guidance is provided for a low-permeability tight reservoir fracturing design decision. 本发明提供的一种低渗致密储层可压性确定方法、系统及计算机设备，具体包括：将影响致密储层体积压裂可压性的因素的参数值；标准化处理所述参数值，获得标准化值；对影响致密储层体积压裂可压性的因素进行归一化处理，建立雷达图，形成各个因素之间的多边形面积；根据所述多边形面积的大小定量确定低渗致密储层的
