Abstract: As a high risk,high technology and high investment industry,offshore oil industry has high requirements for safety and environmental protection. High quality and perfect basic work is the foundation and prerequisite for safe and stable production of offshore oilfields. “3 + 1” comprehensive performance evaluation method is achieved by designing a reasonable comprehensive performance calculation formula,establishing a list of positive and negative aspects for employees,focusing on quantifying the completion of basic tasks,and considering the outstanding achievements of employees in innovation and efficiency,as well as the recognition of their work by team members. At the same time,one vote veto is implemented for employees who have made significant mistakes in safety,environmental protection,integrity and self-discipline,in order to ultimately establish an oilfield work philosophy that emphasizes the importance of basics,encourages improvement,promotes unity,and respects rules.

Key words: offshore oil, performance evaluation, quantification, philosophy
