CBM reservoiring process reflects the enrichment and reservoiring history of CBM.

Owing to its more intensive nonhomogeneity, the limitation by recognition and information during the early stage of gas pool development, the west Sichuan dense clastic rock gas pool is hard to be accurately judged and predicted for its beneficial reservoiring blocks by geological and geophysical exploration.

After the dry gas reservoir with low and extremely-low permeability,but without identified edged and bottom water has been produced for a period,the formation pressure of different areas decreases inhomogeneously,while the gas saturation (S g) changes slightly,which can not be used to describe accurately the distribution of remaining gas.
