Zusammenfassung:The invention provides a method and device for evaluating reservoir fracture network performance. The method comprises the steps of generating mineral brittleness parameters of rock are generated according to mineral components of the reservoir rock; generating a mechanical brittleness parameter of the rock according to the conventional logging data or rock mechanical experiment data of the reservoir; generating crustal stress parameters of the reservoir according to the conventional logging data of the reservoir and the test fracturing data of the reservoir; according to the imaging logging data of the reservoir, calculating the native fracture activation pressure of the reservoir; and generating an evaluation result of the fracture network performance of the reservoir according to the mineral brittleness parameters, the mechanical brittleness parameters, the crustal stress parameters and the native fracture activation pressure. The invention can provide a method for evaluating reservoir fracture network per
