The invention relates to a basin edge complex tectonic zone normal-pressure shale gas horizontal well integrated design method. In the design process, for the characteristics that such as the Southeast Chongqing basin edge transition zone is strong in tectonic deformation, and the geological condition is complex, through superposition evaluation of a structural figure, a burial depth figure, a porosity figure, a gas content figure, a pressure coefficient figure and a curvature figure, geology and engineering optimal dessert areas are optimized, well sites are deployed, the seismic attribute isused for predicting stratum seam hole development situation, interval intvl losing is avoided, the well drilling aging is improved, and through target window and horizontal well orientation optimization and curvature prediction, the reservoir stratum fracturing effect is improved, the reservoir stratum capacity is sufficiently released, the single well economic benefits are improved, the technical support is provided for
