Heavy oil is recovered from reservoirs using steam-assisted technology, which can lead to H₂S generation if the oil is relatively sulfur-rich. We have used laboratory aquathermolysis to simulate the steam-assisted gravity drainage process and have compared free heavy oil to that contained within the mineral matrix. The presence of a mineral matrix was found to affect the amount of H₂S produced and the chemical properties of the oil generated. Our findings show that H₂S production is initiated by the presence of naturally occurring minerals at specific temperatures and pressures and production techniques that avoid these conditions will minimize H₂S production.

在重油蒸汽辅助回收过程中矿物在硫化氢生成中的作用

重油从水库使用蒸汽辅助技术，该技术可导致h回收₂一代如果油是相对富硫。我们已使用实验室水热解法模拟了蒸汽辅助重力引流过程，并将游离重油与矿物基质中所含的重油进行了比较。发现矿物基质的存在会影响所产生的H ₂ S量和所产生的油的化学性质。我们的发现表明，H ₂ S的产生是由在特定温度和压力下天然矿物的存在引发的，避免这些条件的生产技术将使H ₂ S的产生最小化。
