Study of factors influencing the performance of wells and in-field transport systems
K.A. Mammadov PhD in Tech. Sc. - “Oil-Gas Scientific Research Project” InstituteThe article is devoted to the study of factors affecting the operational performance of wells and intra-mine transportation systems.
In order to increase the uninterrupted service life of pipelines in wells and intra-mine transportation systems, reduce transportation costs, the cost of the product in general, and reliably protect the environment, regular study of the corrosion aggressiveness of transported production products, investigation of factors causing erosion and mechanical erosion, and improvement of protection methods against it are among the urgent issues.
The corrosion aggressiveness of soils contaminated with produced waters has been studied. In order to investigate the effect of the corrosion aggressiveness of contaminated soils on the corrosion of the external surfaces of pipelines, chemical analyses were conducted to determine the amount of aggressive ions present in soil samples taken from separate parts of the areas where the intra-mine pipelines of “Bibiheybatneft” and A. Amirov Oil and Gas Production Department (OGPD) passed. The presence of more than 300 mg of sulfate and chloride ions per liter of the studied groundwater indicates its high aggressiveness. The sufficiently high content of sulfate ions in these groundwaters not only creates chemical aggressiveness, but also creates favorable conditions for the reproduction of sulfate-reducing bacteria (SRB).
As a result of the studies, it was determined that the soils in the mine area contaminated with produced water as a result of accidents have a very high corrosion aggressiveness, which has increased by 2 times compared to uncontaminated soils. This is due to the excess amount of aggressive sulfate and chloride ions in the soil contaminated with produced water. In addition, an increase in the microbiological aggressiveness of this soil was also determined. Corrosion of mine pipelines passing through contaminated soil areas should be considered as it will ultimately have a negative impact on the loss of the product transported by those pipelines.
