Abstract

一种海底天然气水合物开采监测系统，包括设置在海洋平台组件（11）上的大气监测单元、海水监测单元、海床监测单元和海底储层监测单元。

Description

一种海底天然气水合物开采监测系统 技术领域
本申请属于海底天然气水合物开发技术领域，具体涉及一种海底天然气水合物开采监测系统。
背景技术
天然气水合物是甲烷、乙烷、丙烷等低分子质量的烃类气体在低温高压条件下与水结合形成的一种笼状结构的冰样固态化合物，可直接燃烧，俗称“可燃冰”。
自然界中天然气水合物广泛分布于300m～3000m水深的海域，少部分位于永久冻土带，多以甲烷水合物为主90％，蕴藏量巨大。据测算，全球天然气水合物所含天然气约为3×1016m 3～3×1017m 3，其热当量相当于目前已探明的所有化石燃料包括煤、石油和天然气总和的2倍，可供人类使用约1000年。与常规油气资源相比，天然气水合物燃烧产生污染较少，是一种真正的清洁能源，有望在21世纪成为继页岩气、致密气、煤层气、油砂之后储量最大的、理想的可替代能源之一。
虽然天然气水合物的研究工作得到世界上很多国家的重视，但是开采技术难、开发成本高、环境隐患大等问题成为制约海底天然气水合物开采的瓶颈，特别是开采带来的环境安全问题。天然气水合物的开采会改变天然气水合物赖以赋存的温压条件，引起天然气水合物的分解。在天然气水合物的开采过程中如果不能有效地实现对温压条件的控制，就可能产生一系列环境安全问题，如温室效应的加剧、海洋生态的变化以及海底滑塌事件等。
针对上述海域天然气水合物开采过程中可能出现的环境风险，海域天然气水合物开采过程必须进行全面的监测。然而，目前在日本南海海槽Nankai Trough和中国南海神狐海域进行的4次海域水合物试采项目虽各自都进行了一定的监测设备布置，但均未全面地对海底天然气水 合物开发的上述四方面环境安全问题展开监测，更未形成一套完善的海底天然气水合物开发环境监测系统。
