Prediction Model of Sulfur Precipitation in Gas Well with High H2S Content

For the gas well with high H2S content,the process of sulfur deposition including the sulfur dissolution, precipitation, migration and deposition is a quite complex process. Relative to the solubility of sulfur under certain temperature and the pressure, the sulfur will be separated out when the content of sulfur in high sour gas is surpassed. Based on the theories of mass conservation, momentum conservation, energy conservation, and the transfer of heat in the radial directions of well bore, we established the prediction model of the sulfur precipitation in the high H2S content gas well by using Roberts thermal empirical equation. In view of the examples, the sulfur separation at different levels of production is calculated and discussed by using the self-programming computer.
