Sulfur deposition damage is one of the most important problems in sour gas reservoir development. With decreasing pressure and temperature near bore zones, solid elemental sulfur may deposit and block pore. What´s worse, it reduces the inflow performance of sour-gas wells. Based on the comprehensive analysis of deposit and block process, solid elemental sulfur motional and mechanical model were established with irreducible water considered. The results indicated that precipitated solid elemental sulfur did not move a long time in pore; they could in-suit deposit. Irreducible water plays an important role in sulfur deposition. The former precipitated solid blocked pore and the latter solid could be carried if gas velocity was big enough.
