本发明提供了一种低碳化海洋水合物开采及发电利用系统,包括海上浮式开采平台和设于海底的水平井网系统;水平井网系统用于通过降压方法从预热的甲烷水合物层中获得甲烷气体,并通过输出管网将甲烷气体输至所述海上浮式开采平台;海上浮式开采平台上设置船载直接燃烧透平发电系统,船载直接燃烧透平发电系统将获取的甲烷气体进行发电;还包括设于海底的废弃井,船载直接燃烧透平发电系统将发电过程中产生的CO2加压后,通过输入管网输至废弃井中。本发明解决了目前开采方面海洋地层中水合物降压或者注热分解过程中分解界面较小的局限,同时解决效率低、CO2排放等问题。

    The invention provides a low-carbon marine hydrate mining and power generation utilization system. The low-carbon marine hydrate mining and power generation utilization system comprises an offshore floating mining platform and a horizontal well pattern system arranged on the seabed; the horizontal well pattern system is used for obtaining methane gases from a preheated methane hydrate layer through a depressurization method, and conveying the methane gases to the offshore floating mining platform through an output pipe network; the offshore floating mining platform is provided with a ship-borne direct combustion turbine power generation system, and the ship-borne direct combustion turbine power generation system generates power from the obtained methane gases; and the system further comprises an abandoned well arranged on the seabed, wherein the ship-borne direct combustion turbine power generation system pressurizes CO2 generated in the power generation process and transports the CO2into the abandoned well through an input pipe network. The low-carbon marine hydrate mining and power generation utilization system provided by the invention solves the limitation that a decompositioninterface of the hydrate in the marine stratum in the depressurization or heat injection decomposition process is small in the current mining, and simultaneously solves the problems of low efficiency, CO2 emission and the like.
