The oil industry is the industrial sector that exploits and refines oil (including natural oil, oil shale and natural gas). It is composed of oilfield geological exploration, oilfield development and oil exploitation, transportation, refining and processing and other units. Petroleum is the "blood" of industry and an important industrial energy source. The development of the oil industry needs to do the following work: (1) Do a good job in geological exploration, increase industrial reserves, and determine a reasonable proportion of reserves and extraction; (2) Strengthen scientific and technological research on oil extraction, and study and select reasonable extraction technologies and oil according to natural conditions and factors such as the size of reserves and the level of natural pressure in the oil layer. Well distribution to improve the exploitation rate of oil fields; (3) Strengthen the construction of supporting projects for oil field exploitation, and choose reasonable transportation modes at the same time as oil field development; (4) Improve the production technology and management level of oil refining and processing to ensure the automation and continuity of the production process.
