Zusammenfassung:The invention relates to a method for designing re-fracturing energizing temporary plugging fracturing parameters of a horizontal well. According to the technical scheme, the method comprises the following steps that structural modeling and small-layer modeling are carried out; on the basis of lithofacies modeling, reservoir attribute modeling is carried out; carrying out natural fracture modeling; interpreting a three-dimensional rock mechanical field based on an indoor mechanical experiment and a single well logging interpretation result; in combination with primary fracturing microseismic data, carrying out inversion on a primary fracturing fracture transformation form, and then carrying out historical fitting through a pore pressure field and fracture parameters of primary fracturing; introducing the pore pressure fields at different moments into a geomechanical simulator to carry out dynamic rock stress field calculation, and carrying out dynamic stress field calculation; selecting a low-value region of
