摘要： A method for scavenging hydrogen sulfide from fluids produced into a well includes pressurizing a hydrogen sulfide scavenging reagent to a pressure above a pressure in the well. At selected times the pressurized hydrogen sulfide scavenging reagent is enabled to flow into the well. Fluid produced from the well is stored at a pressure extant on the well. At selected times an hydraulic connection is made between the stored, produced fluid and the well so that the produced fluid flows into the well by gravity. In some embodiments, the reagent is triazine.
