本研究对辽河油田有害气体（H2S）的分布及治理进行了调查。研究发现，稠油热采过程中会产生大量有毒气体（H2S）。 H2S气体主要是在油藏中发生的热化学硫酸盐还原(TSR)或原油中含硫化合物(TDS)的热分解过程中形成的。 H2S 的产生由热恢复时间、温度和注入的化合物控制。注入化合物中SO42−的量是对TSR反应速率影响最大的因素。因此，为了防止H2S的形成，在稠油热采过程中应定期进行有效的监测，并提供足够的H2S吸收剂。结果表明，稠油开采中应大力减少SO42源，抑制油藏H2S生成。建议采用原位燃烧或脱硫剂吸附来降低 H2S 含量。 H2S的预测和预防对于稠油生产具有重要意义。这将最大限度地减少环境和人类健康风险以及设备腐蚀。
The distribution and treatment of harmful gas (H2S) in the Liaohe Oilfield, Northeast China, were investigated in this study. It was found that abundant toxic gas (H2S) is generated in thermal recovery of heavy oil. The H2S gas is mainly formed during thermochemical sulfate reduction (TSR) occurring in oil reservoirs or the thermal decomposition of sulfocompounds (TDS) in crude oil. H2S generation is controlled by thermal recovery time, temperature and the injected chemical compounds. The quantity of SO42−in the injected compounds is the most influencing factor for the rate of TSR reaction. Therefore, for prevention of H2S formation, periodic and effective monitoring should be undertaken and adequate H2S absorbent should also be provided during thermal recovery of heavy oil. The result suggests that great efforts should be made to reduce the SO42−source in heavy oil recovery, so as to restrain H2S generation in reservoirs. In situ burning or desulfurizer adsorption are suggested to reduce H2S levels. Prediction and prevention of H2S are important in heavy oil production. This will minimize environmental and human health risks, as well as equipment corrosion.
