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