硫沉积对高含硫气藏气井生产影响
Impact of sulfur precipitation in production of sour gas wells
摘要
Abstract
In order to study the impact of elemental sulfur deposition and pressure-sensitive effects in developing sour gas reservoirs,the precipitation mechanism of elemental sulfur deposition and pressure-sensitive effects in high sulfur gas reservoirs are analysed.Elemental sulfur deposition and pressure-sensitive effects are considered together when establishing a mathematical model of gas well under the condition of closed outer boundary and definite production inner boundary based on the radial gas percolation theory.In this model,compression factor is inversely proportional to the pressure because of the pressure-sensitive effects.The curves from calculating this mathematical model show the pressure distribution at different radial distance with considering the effect of sulfur deposition and pressure-sensitive.The area where is severely damaged in the sour gas reservoirs can be easily identified by the analysis of the curves.It is helpful to put forward a better gas well working system to reduce sour gas reservoirs undermine the protection measures as much as possible.关键词
