Abstract: In order to improve mining benefits, an oilfield plans to select a large-scale high pour-point oil block to carry out a pilot test of weak alkaline ASP flooding in high pour-point oil reservoirs and explore a new mining method. In this paper, according to the national occupational health laws and regulations, pre-assessment of occupational hazards for a high pour-point oil reservoir chemical flooding surface engineering project in an oilfield was carried out. Through the method of occupational health investigation and evaluation, the occupational disease risk factors of this project were identified, the degree of the risk was analyzed and the project feasibility from the prevention and treatment of occupational diseases was concluded. This provided scientific basis for the management and protection of occupational hazards in the process of production and operation.

Key words: occupational hazard, pre-assessment, high pour-point oil reservoir, chemical flooding
