The invention relates to an oil field acidifying hydrogen sulfide removing agent and a use method thereof, belonging to the technical field of hydrogen sulfide removal. The composition of the oil field acidifying hydrogen sulfide removing agent in the present invention includes: pyrophosphoric acid or pyrophosphate, polyphosphoric acid or polyphosphate; the molar ratio of the two is: pyrophosphoric acid or pyrophosphate: polyphosphoric acid or polyphosphate= (1 to 2.5): 1. The hydrogen sulfide desulfurizer in the present invention utilizes the hydrolysis of phosphate to form phosphate radicals, and converts hydrogen sulfide into sulfur element, with high reaction efficiency and good removal effect; meanwhile, the hydrogen sulfide remover has good compatibility with acid, It can be directly prepared with acid solution, the preparation is simple, and the use is flexible and convenient. |
