Abstract: Combining with the actual situation of quantitative assessment on safety risks in Shengli Oilfield, this paper selects HAZOP /LOPA to assess nodes and BOWTIE to assess intermediate events. It gives full consideration to the escalation factors such as hidden dangers of work safety. The paper introduces safety hazard correction factors to correct the initial risks and protective measures. It makes reasonable selection of failure probability value for management measures. It calculates the residual risk values strictly and verifies the role of the current risk management and control measures. Then the paper proposes new risk management and control measures. It formulates and implements risk reduction plans to ensure that the residual safety risks are always in a quantifiable, acceptable, and controllable state.

Key words: safety risk, quantitative assessment, initial risk, protective measures, escalation factors, residual risk
