利用高能气体压裂技术开采天然气水合物可行性分析

High-energy Gas Fracturing Technique to Exploit Natural Gas Hydrate Reservoir

天然气水合物是一种新型洁净能源,其蕴藏量约为现有地球化石燃料含碳量总和的两倍,天然气水合物资源开发已经引起了全世界的关注。提出了先利用高能气体压裂技术对储层进行压裂后再结合电磁加热或降压法开采,或者利用加热法和降压法结合开采的思路,以期达到经济有效开采的目的。

Natural gas hydrate, which is widely distributed with huge reserves and equals twice total carbon reserves of coals, oils and natural gases etc conventional fossil fuels around the earth, is a kind of nonpolluting and high quality energy resource in the future. How to exploit and develop this new energy is becoming a main concern among many governments. The methods proposed for methane gas dissociated from solid hydrate were compared, including the thermal stimulation method, the depressurization method, the inhibitor injection method, and the replacement method etc. In order to develop this new energy economically and effectively, high-energy gas fracturing is proposed in this paper, we can combine high-energy gas fracturing with microwave heating technique and the depressurization method or some other methods.
