초록
석탄층 메탄가스는 신(新)가스자원의 대표적인 한 분야로서, 기존의 천연가스나 석유처럼 자원의 편중이 없어 비산유국에서도 접근성이 용이한 특징을 갖고 있다. 게다가 석탄층 메탄가스 개발 및 사용을 통해 에너지자원 확보와 지구온난화 예방이라는 일석이조의 효과를 얻을 수 있어 최근 석탄층 메탄가스 개발의 중요성이 높아지고 있으며, 미국을 비롯한 여러 석탄보유국들은 석탄층 메탄가스의 생산을 이미 진행하고 있다. 하지만 국내의 경우, 지질조사나 탐사기술과 같은 기초적인 기술은 보유하고 있으나, 생산관련 기술은 이제 초입 단계이며, 선진국과의 기술 수준 비교에서 큰 차이를 보인다. 이에 본 연구에서는 석탄층 메탄가스의 개발현황을 파악하고, 석탄층 메탄가스 개발을 위한 핵심기술을 분류함으로써, 향후 기술개발 전략 방향을 제시하였다.
Abstract
Coalbed methane (CBM) is one of the representative areas of unconventional gas. It allows easier access for a non-oil country because, unlike conventional gas or oil reserves, CBM is not concentrated in specific major area. The importance of CBM resource is being emphasized because of its contribution in both energy resources security and greenhouse gas emissions prevention through its production and use. US and other countries, which possess coal formation have been and expected to continue producing CBM. However, Korea is at the early stage of production-related technologies and only has the basic technology to do a survey and exploration of the domestic CBM. Based on the comparison of Korea and other developed countries regarding technologies, a distinct difference can be observed. This study presents the direction of technology advances in Korea by investigating the development status and classifying the technology of CBM.
