- 減圧法によりメタンハイドレートを採掘する方法において、採掘対象となるメタンハイドレート層の近傍の二酸化炭素がハイドレートとなる温度・圧力条件の地層の間隙に、前記間隙よりも小さな液体二酸化炭素の微粒子を水に分散させたエマルジョンを注入し、二酸化炭素ハイドレートの生成熱によって前記メタンハイドレート層を加熱することを特徴とし、
前記地層は、メタンハイドレートを含む層からメタンハイドレートを採掘する際に前記メタンハイドレートを含む層の圧力が制御されて、メタンハイドレートの採掘後にその温度が前記液体二酸化炭素の二酸化炭素ハイドレートへの相転移温度未満に制御されている地層及びその近傍の地層であるメタンハイドレート採掘方法。 - 前記エマルジョン中の前記液体二酸化炭素と前記水との混合割合を変化させ、前記エマルジョンの単位量当たりの二酸化炭素ハイドレート生成時の発熱量を、前記地層の温度を前記液体二酸化炭素の二酸化炭素ハイドレートへの相転移温度に上昇させ得る発熱量に制御してから前記地層に前記エマルジョンを注入し、前記相転移温度は二酸化炭素ハイドレートの生成と分解が平衡状態となる温度である請求項1に記載のメタンハイドレート採掘方法。
- 前記エマルジョン中の前記水の温度を変化させることにより前記エマルジョンの温度を前記地層における前記液体二酸化炭素の二酸化炭素ハイドレートへの相転移温度またはそれよりも0.1℃高い温度に制御してから、前記エマルジョンを前記地層へ注入し、前記相転移温度は二酸化炭素ハイドレートの生成と分解が平衡状態となる温度である請求項1または2に記載のメタンハイドレート採掘方法。
