Modeling of Sulfur Deposition in Sour Gas Reservoir
In order to scientifically and accurately predicate the damage of sulfur deposition in sour gas reservoir.Glomeration mechanism of precipitated sulfur in pores was analyzed,based on conventional black-oil reservoir simulator,given the effect of sulfur deposition and irreducible water,a reservoir damage model is established in the presence of non-Darcy flow,the model can be used to describe the change of pressure with deposited sulfur.The results show that when reservoir pressure is lower than critical pressure,higher saturation degree of irreducible water may lead to pressure drop more quickly and velocity of sulfur precipitation become faster,gas limited production time become shorter when Non-Darcy flow is considered.
