Abstract: With the implementation of steam flooding and SAGD, the oil wells containing hydrogen sulfide in associated gas of heavy oilfields are increasing; their scopes are expanding and their concentration is increasing as well. The maximum concentration has exceeded 20,000 mg/m3, far beyond the safe concentration. Because hydrogen sulfide has not been found in the early stage of heavy oilfield exploitation, there are still some shortcomings in hydrogen sulfide formation mechanism and prevention technology. In order to avoid the occurrence of hydrogen sulfide accidents and ensure the smooth production of heavy oilfields, this paper studies the hydrogen sulfide absorption treatment fluid, which provides support for the development of hydrogen sulfide prevention technology. This is of great significance for oilfield enterprises to promote the sustainable and stable development.
