Incineration technology, which is to make the waste water containing H at well site 2 S, mixing the sleeve gas and natural gas, directly igniting, and mixing H 2 S is burnt out, although the technology can eliminate H 2 S, but produces SO 2 The pollution to the atmospheric environment is caused; the return oil pipeline is mainly communicated with an oil sleeve or a booster pump, and the sleeve gas is conveyed to the oil pipeline and enters the joint station for desulfurization treatment. For an operation well, a well is usually washed before operation, and for an oil well containing hydrogen sulfide, most of the current oil field is treated by directly injecting strong alkali solution (sodium hydroxide solution with the pH value of 11) into a casing by using a pump truck, and the annular cross section of an oil sleeve is about 5-6 times of that of the oil sleeve due to no throttling measure in the injection process, so that after the well washing solution flows into the annular of the oil sleeve from the oil sleeve, the well washing solution cannot form a full flow state and flows down along the inner wall of the casing in a small flow mode, the contact area of the well washing solution and the casing gas is small, the mass transfer efficiency is low, the hydrogen sulfide removal effect in the gas phase in the casing is poor, and when the well washing is finished, the hydrogen sulfide-containing casing gas with a certain height still exists at the upper part of the casing, so that when an oil outlet pipe is started, the life of operators is safe.
