The invention belongs to the technical field of oil and gas reservoir development, and particularly discloses an oil and gas reservoir horizontal seam horizontal well drilling and completion fracturing transformation method which comprises the steps of determining a low vertical stress stratum, determining the effective thickness of the low vertical stress stratum, selecting a horizontal well track and optimizing the horizontal well track through well drilling design software. The problem that a low vertical stress stratum cannot be developed in a horizontal well fracturing transformation mode is solved, after fracturing transformation is carried out, a horizontal section is cut into a plurality of horizontal seam planes parallel to the stratum through formed artificial cracks, the transformation area of an oil and gas reservoir is increased through the stacked horizontal seam planes, and the oil and gas reservoir is improved. And the single-well oil-gas yield and development benefits can be improved. 本发明属于油气
