A method of scavenging hydrogen sulfide from a sour gas well includes injecting a nanoemulsion through a borehole into a subterranean geological formation including a gaseous hydrocarbon composition including hydrogen sulfide. The nanoemulsion includes a mineral oil, water, a surfactant, and an additive. The water is a continuous phase of the nanoemulsion. The surfactant is selected from a group consisting of a sodium dodecylbenzenesulfonate, a cetyltrimethylammonium bromide, and a nonionic polyoxyethylene detergent. The additive is selected from a group consisting of a silver salt and a copper salt. The method includes circulating the nanoemulsion in the borehole in the subterranean geological formation to contact the nanoemulsion with the hydrocarbon composition and reacting the nanoemulsion with the hydrogen sulfide in the gaseous hydrocarbon composition to form a production gas including less than 5 parts per million (ppm) of hydrogen sulfide.

The invention relates to the technical field of data analysis, and discloses a shaft and pipe network production allocation risk assessment system for a sulfur-containing gas reservoir, and the system comprises an integrated model which comprises a gas reservoir model, a shaft model and a pipe network model; the configuration module is used for configuring configuration parameters of the integrated model and inputting simulated production allocation value parameters of each production node; a storage module; the extraction module is used for extracting the production allocation result of the integrated model stored in the storage module; the early warning judgment module is used for comparing the production allocation result with configuration parameters so as to judge whether early warning is carried out or not; the sulfur deposition judgment module is used for calculating the sulfur solubility according to the production allocation result and comparing the sulfur solubility with the actual sulfur content so as to judge whether to give an early warning or not; and the display module is used for displaying the configuration result and the judgment results of the early warning judgment module and the sulfur deposition judgment module. The safety and feasibility of the production allocation scheme can be improved.
