天然气水合物开采理论及开采方法分析

Analysis on the Mining Theory and Methods of Natural Gas Hydrate

天然气水合物在地球上含量巨大,是未来极具开发潜力的清洁不可再生自然资源,虽然其含量巨大令研究者感到振奋,但是目前为止任未有一套真正意义上成熟完整的天然气水合物开采理论。在前人基础上总结分析了传统的天然气水合物开采机理,并叙述了一些新型的天然气水合物开采设想。通过分析比较提出了水合物大规模开采需要采用联合开采设想。同时,也叙述了天然气水合物若开采不当,则可能带来的最严重后果——温室效应加剧。最终,提出开采前,需要结合地质勘探技术,获得开采层区域三维实景数据图,防止因意外坍塌而导致的天然气泄漏。

Natural gas hydrate, which is widely distributed in nature, is a kind of potential clean and nonrenewable natural resource in the future. But, a set of relatively complete theory about its production process is still not formed so far. In this paper, the traditional natural gas hydrate production mechanism was summed up and analyzed, and the assumption of some new types of natural gas hydrate exploitation methods was described. Through comparing and analyzing, the idea about natural gas hydrate large-scale mining was put forward： the combined mining modes should be adopted. Meanwhile, it’s pointed out that improper exploitation of natural gas hydrate maybe causes the most serious consequence, the greenhouse effect worsening. Finally, in order to prevent accidental collapse to trigger natural gas leak, three-dimensional imaging data of mining area should be got by combining with the geological exploration technology.
