摘要：

For extra-low permeability sandstone reservoirs, traditional well test analysis techniques are always limited by wellbore storage coefficient and the low flow velocity in the porous media. Results derived using traditional well test analysis techniques are meaningless or useless. A deconvolution method based on the newly robust solution algorithms is applied for extra-low permeability sandstone reservoirs. Deconvolution codes were developed based on von Schroeter deconvolution algorithm and Levitan deconvolution algorithm. Though the study is based on synthetic cases and a field case, it is proved that the deconvolution algorithm works well in well test analysis of extra-low permeability sandstone reservoirs.
