Oil exploitation

The petroleum industry is the industrial sector that extracts and processes 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. 

Oil is the "blood" of industry and an important industrial energy source. To develop the petroleum industry, the following work needs to be done: 


(1) do a good job in geological exploration, increase industrial reserves, and determine a reasonable proportion of reserves and production; 


(2) Strengthen scientific and technological research on oil exploitation, and study and select reasonable exploitation technology and oil well distribution according to natural conditions and factors such as the size of reserves and the natural pressure of the oil layer, so as to improve the recovery rate of the oilfield;


(3) Strengthen the construction of supporting projects for oilfield exploitation, and choose reasonable transportation modes while developing oilfields; 


(4) Improve the production technology level and management level of petroleum refining and processing to ensure the automation and continuity of the production process.
