摘要

With the characteristics such as lowporosity, low permeability and low gas saturation, tight sandstone reservoirsalmost have no natural capacity and need to be fractured (or fracturing) forproductivity. Therefore, fracturing capacity prediction is very necessary.However there were so many factors, and the relations between the factor andthe post-frac productivity are complex. In this study, first of all factors areconcluded from the gas well stable productivity formula, then I used factoranalysis to look for the main factors from the logging parameters andfracturing parameters in SULIGE area. This study could provide basal referencesfor the gas post-frac productivity prediction in tight sandstone reservoirs.
