STUDY OF MINING AND GEOLOGICAL FEATURES OF PROMISING CRUDE OIL-PRODUCING AREAS OF IRAQ

Abstract

Iraq is located on the northeastern parts of the Arabian Plate, which has been particularly exposed to tectonic movements in past geological periods, where there are several giant fields that contain most of the country’s oil reserves. The structural features of the oil fields of southern Iraq (Mishrif and Zubeir) form a number of factors that complicate the construction and operation of wells for oil production in the region.Possible negative consequences of the corrosion processes of oil and gas equipment and the prospective use of new technologies and materials were considered, taking into account the fact that waterflooding is currently the main technology in oil production in Iraq, which in these conditions requires a large amount of water and carries a number of negative factors that complicate operation of oil production equipment.These main factors are the content of acid gases (hydrogen sulfide and carbon dioxide), high mineralization of formation water, mainly due to the presence of chloride ions, elevated temperature, which is due to the depth of drilling and well operation. The negative consequences of corrosion of oil and gas equipment are given. The study was based on an integrated approach, which was carried out by analyzing data on the formation of geological conditions in southern Iraq (tectonics, stratigraphy, lithological-facial and hydrological analysis), generalization of world experience in oil production, use of oil and gas resources.
