With the increase of society's demand for energy, the development of oil and gas resources has accelerated, and the environmental problems caused by it have become more and more prominent. Offshore oil and gas development (OaGD) engineering is a complex system engineering, which determines the The environmental problems are inevitably complex and diverse. This paper studies the current situation of OaGD in sea area A from 2015 to 2020, and finds that in the process of OaGD in this sea area, the discharge of oily production water increased in the early years, resulting in serious seawater pollution. Based on this, this paper calculates the contribution rate to analyze the impact of each link in the OaGD project in this sea area on the environment, and evaluates the impact of OaGD on the environment through five indicators: resource consumption, global warming, acidification, optical ozone, and biological toxicity. The results show that the oil and gas gathering and transportation stage of offshore OaGD has the least impact on all aspects of the environment, followed by the geological exploration stage, and the oil production stage has the greatest impact on the environment. Aiming at the problems existing in the OaGD and governance in this sea area, this paper also puts forward suggestions for improvement.
