Optimization of the number of marine ecological environment survey stations for offshore oil and gas development projects
摘要
Abstract
China's heavy dependence on foreign oil highlights the significance of offshore oil and gas development as a major strategy for energy substitution in petrochemical sectors.According to Chinese laws and regulations,activities related to offshore oil and gas development must carry out sea use demonstrations and corresponding ma-rine ecological environment surveys.However,practical marine ecological surveys often establish stations in excess of the minimum guideline requirements.This study applies a spatially uniform screening survey station method using data from seawater quality,sediment quality,and marine ecology surveys conducted over the past 5 years in the Bozhong offshore oilfield,located in the Bohai Sea.Following screening,the number of stations met the mini-mum requirements.Statistical and distribution characteristics of each typical survey index data were compared and analyzed before and after screening.The findings indicate that comprehensive coverage of marine ecological envi-ronment survey stations across the Bozhong Oilfield adequately reflects environmental characteristics when meet-ing minimum guidelines.This approach can be applicable to other offshore oil and gas development projects in the Bohai Sea,East China Sea,and South China Sea.Therefore,this study provides valuable guidance for planning and conducting marine ecological environment assessments in the application and approval processes of offshore oil and gas development projects.关键词
