海南省近海莺歌海盆地CCS适宜性和潜力
Suitability and storage potential for offshore CCS in the Yinggehai Basin,offshore Hainan Province
摘要
Abstract
The Yinggehai Basin,South China Sea,offers advantages for implementing offshore CCUS(carbon capture,utilization and storage),but the basin-scale suitability and storage potential remain insufficiently quanti-fied.To assess the geological suitability,estimate storage capacity,and propose a provincial CCS(carbon capture and storage)planning framework for Hainan,based on integrated geological,borehole,and seismic datasets,we analyzed stratigraphic pressure-temperature conditions,reservoir-caprock assemblages,and depositional facies in the Yinggehai Basin to delineate suitable areas and favorable structural targets for CO2 storage.The storage poten-tial estimates were combined with Hainan provincial CO2 emission characteristics to inform offshore CCS plan-ning recommendations.The Yingdong Slope and the Lingao Uplift meet the temperature-pressure and reservoir-caprock requirements for CO2 geological storage and thus were identified as the basin's secondary structural units most suitable for saline aquifer storage.The estimated effective storage capacities are 2.13 Gt and 1.06 Gt,re-spectively.Two favorable structural targets were located:HK30-3 and LG20-1,where the estimated effective stor-age capacities are 43 Mt and 343 Mt,respectively.Notably,HK30-3 lies at an approximate straight-line distance of only approximately 100 km from Hainan's major industrial centers and is therefore suitable as a demonstration target for ten-million-ton scale offshore CCS in Hainan.The Yinggehai Basin possesses the geological conditions required for offshore CO2 geological storage and exhibits billion-ton scale effective storage capacity.This study provided a scientific basis for Hainan Province to realize carbon neutrality toward net-zero emissions in coastal re-gions.关键词
