In order to handle the contradiction between the input and output in the low-permeability oil and gas reservoir development and to meet the needs of the rational production rate and stable production period to obtain maximum economic benefits, the bulk reformation technique is applied more and more widely in every oil and gas field. In this paper, by comprehensively applying oil reservoir engineering method, numerical simulation theory, seepage flow mechanics theory, oil production engineering and numerical calculation method, etc., starting from the bulk reformation of the tract and in view of the effect of both the low-velocity non-Darcy seepage flow in the low-pearmeability tight gas reservoirs and the high-velocity non-Darcy seepage flow in the man-made fractures, a new and more perfect bulk fracturing simulation mathematical model for low-permeability tight gas reservoirs is set up for the first time, a numerical model is derived and the bulk fracturing simulation software for low-permeability tight gas reservoirs is drawn up, providing a powerful tool for drawing up the bulk fracturing reformation plan for low-permeability tight gas reservoirs.
