The spirit of petroleum is the spiritual wealth nurtured by the persistent struggle and dedication of the petroleum industry, and it is the driving force that motivates the petroleum people to fulfill their duties and overcome difficulties. All personnel of Shandong Wuersi have been learning the spirit of petroleum, striving to become Iron Man style employees, working side by side with the company, forging ahead, and exploring new prospects for the stable development of the company.

In the development process of China's petroleum and petrochemical industry, the petroleum spirit, centered around the "Daqing spirit", "Iron Man spirit", "Hard work and hard work", and "Three Old and Four Strict", has always been the soul and foundation of the petroleum and petrochemical industry.  

The Daqing spirit originated from the world-renowned Daqing Oil Battle in the early 1960s and is an important component of the Chinese national spirit. The spirit of Daqing mainly includes the patriotic spirit of striving for national glory and national morale; An independent and self-reliant spirit of hard work and entrepreneurship; The scientific and pragmatic spirit of emphasizing science and "three old and four strict"; A spirit of dedication that embraces the overall situation and shares the worries of the country. In summary, it means "patriotism, entrepreneurship, seeking truth, and dedication".

"Iron Man" is a nickname given to Wang Jinxi, an oil worker, by the society in the 1950s and 1960s, while the iron man spirit is a high summary of Wang Jinxi's lofty thoughts and excellent morality, and also reflects the spirit of our oil workers. The Iron Man spirit has rich connotations, mainly including:

The patriotic spirit of "sharing the worries of the country and boosting the morale of the nation", the selfless spirit of "would rather live 20 years less than work hard to win the big oil field", and the spirit of hard work of "if conditions permit, we must go up, but if conditions permit, we must go up"; The scientific and pragmatic spirit of "doing work must withstand the inspection of generations" and "practicing hard work and direct skills for the revolution"; Willing to be an old scalper for the Party and the people for a lifetime, with a spirit of dedication and hard work. The Iron Man spirit has immortal value and eternal vitality in the past, present, and future.

The development of China's petroleum industry to this day has been achieved one after another through hard work and hard work. The Party and the people have fully recognized the characteristic of oil workers, and 'hard work and hard work' has become a spiritual endowment for oil workers to overcome difficulties and selflessly contribute. Now, it is still "hard work and hard work" that supports China Petroleum's continuous innovation and development. In the future, in an era of rapidly changing technology, we still need to "work hard and work hard" to make great strides towards the development goal of building a world-class comprehensive international energy company.

The three old and four strict policies mean treating the revolutionary cause as an honest person, speaking the truth, and doing honest things; When dealing with work, there should be strict requirements, strict organization, serious attitude, and strict discipline. Under the repeated advocacy and careful cultivation of the leadership of Shandong Wuersi, through practical work, this excellent style of work has gradually formed in the Shandong Wuersi team.
