Study of the operational experience of parts and structures of oil and gas equipment of the wells in hydrogen sulfide-containing media is up-to-date, because the problems of metal structures reliability are associated not only with hydrogen sulfide corrosion, but also with the quality of their design, construction and operation, this is also important from the standpoint of assessing the influence of these factors on safety of structures operation.
The article deals with the destruction of wells equipment in hydrogen sulfide-containing media. The fragments of the broken tubing, tubing coupling with a crack, undestroyed pipe and coupling.
Based on the results of the spectral analysis of the chemical composition of the stop valves metal parts, determination of hardness and metallographic studies of metal parts, the main causes of equipment failure in the wells of hydrogen sulphide-containing oil and gas condensate fields were determined.
As a result of physicochemical analysis of the metal of destroyed equipment, it was established that the cause of pipe fittings destruction under the influence of hydrogen sulfide-containing (hydrotreated) environments are the dents-risks left from the influence of machine keys for mounting the threaded connections of the tubing, from which, under the conditions of metal complex stress-strain state the microcracks were formed, then merged into through cracks.
