초록

본 논문에서는 이산화탄소 지중저장 시험이 진행 중인 포항 영일만 지역의 지질학적, 암석물리학적, 지질역학적 특성에 대한 분석 결과를 보고한다. 대상 저류층은 영일만 해상 퇴적층 750 m 심도에 다공질, 투수성의 사암/역암층으로 존재하며 상부에 두꺼운 이암층으로 덮고 있다. 해상에 굴착된 탐사시추공에서 측정된 응력 값은 이 지역이 주향이동 단층운동에 유리한 응력체계를 보인다. 측정된 응력 값에 기반하여 다양한 유형의 저류층 파쇄압력, 주변 단층의 전단활성 압력 등에 대한 정보에 대해 고찰하며 분석하였다.

We analyze geological, petrophysical and geomechanical characteristics of a $CO_2$ sequestration test site, Pohang. The target reservoir exists at a depth of 750 m, where porous and permeable sandstones/conglomerates prevail. The reservoir is underlain by thick mudstone formations. We estimate in situ stress conditions using an exploratory wellbore drilled through the target reservoir. The in situ stress condition is characterized by a strike-slip faulting favored stress regime. We discuss various aspects of reservoir fracture pressures and fault reactivation pressures based on the stress magnitudes.
