Abstract
This paper presents the determination of the optimal size, operation pressure, operation temperature by the nodal analysis in the transport and injection facilities in order to effectively inject CO2 into the Gorae V structure. The discharge temperature of CO2 at the platform is determined by 15℃ considering hydrate formation. The optimal values of tubing diameter connected B2, B3/B4, B5 well are 4, 6 and 3 inches, respectively. The influx pressure at the platform should be higher than 797 psia considering discharged pressure and efficiency of compressor. The optimal discharge temperature of CO2 at the transport facility is calculated by 15℃. The stable CO2 injection appears to be feasible when the discharged pressure at the transport facility is above 824 psia in the early stage of injection.
본 연구에서는 B2, B3/B4, B5 층으로 구성된 고래 V 구조 대염수층 내에 CO2를 효율적으로 주입하기 위하여 노달분석을 수행하여 CO2 수송·주입 시스템의 적정 규격, 운영 압력 및 온도조건을 결정하였다. 이때 플랫폼 내 CO2 배출온도는 하이드레이트의 형성을 고려하여 15℃로 결정하였으며, B2, B3/B4, B5 층에 주입되는 주입공의 적정 튜빙내경은 각각 4, 6, 3 인치로 판단하였다. 주입초기시점에 필요한 플랫폼 내 배출압력과 가스압축장치의 압축 비율을 고려하면 플랫폼 내 797 psia의 유입압력이 필요하다. 육상 수송기지에서 배출되는 CO2 온도조건은 플랫폼 내 온도상승효과를 고려하여 15℃로 결정하였으며, 이때 수송압력을 824 psia로 결정하는 경우 안전하게 수송됨을 확인하였다.
