摘要

神华CO2捕获和封存（carbon capture and storage，CCS）示范项目是我国首个全流程煤基CO2捕获和在低孔低渗深部咸水层进行多层注入的CO2封存示范项目，意在通过时移垂直地震（VSP）监测CO2地质封存状况。介绍了CO2地质封存时移VSP技术和监测效果。通过注气前后3次VSP观测，得到了高品质时移VSP资料，研究了一致性处理技术、矢量波场分离和多波成像技术，获得了高分辨率的多波时移VSP剖面，通过深度域标定和多种属性解释对比，分析了注气前后VSP地震响应特征，预测了CO2地下运移范围，达到CCS项目预期监测目标。结果证明，时移VSP技术是监测CO2地质封存与运移的有效技术手段。

Abstract

Shenhua carbon capture and storage (CCS) project is China's first complete process coal-based CO2 capture and multi-layer injection CO2 storage demonstration project in deep saline aquifer with low porosity and low permeability. With Shenhua CCS project as an example

the time-lapse vertical seismic profile (VSP) technology is presented and monitoring results of CO2 storage is obtained. By means of 3 VSP observations before and after gas injection

high quality time-lapse VSP data are obtained. High-quality time-lapse VSP images are achieved by developing consistency processing

vector wave-field separation and multi-component imaging. The seismic response characteristics of VSP before and after gas injection are analyzed by depth domain calibration and multiple attribute interpretation. The range of CO2 underground migration is predicted to reach the expected monitoring target of the CCS project. This case study shows that the VSP monitoring technology is an effective method to monitor carbon dioxide geological storage and migration.
