titleOfInvention | Method for exploiting natural gas hydrate reservoir permeable by cover layer by utilizing branch horizontal well |
abstract | The invention discloses a method for exploiting a cover-layer-permeable natural gas hydrate reservoir by utilizing a branched horizontal well, which belongs to the field of ocean natural gas hydrate exploitation. The multi-branch horizontal well for injecting fluid in the natural gas hydrate reservoir and producing the cover layer can form an upper injection and production system and a lower injection and production system, can effectively prevent methane gas generated by hydrate decomposition from leaking to the seabed through the cover layer, and effectively reduces the environmental pollution risk in natural gas hydrate reservoir exploitation containing the permeable cover layer. |
