二元复合技术开采天然气水合物可行性分析
|
摘要
目前常规的天然气水合物开采方法均处于试验阶段,针对单一开采方法均表现出不同程度的缺点,本文提出了一种二元复合的开采天然气水合物技术。通过对现有的五种常规开采方法进行二元随机组合,在技术、经济、环境安全可行性等几个方面上对组合后的十种方法进行理论可行性分析。结果显示热采联合降压法、热采联合地面分解法、热采联合置换法、注抑制剂联合地面分解法、注抑制剂联合置换法初步显示具有较好的理论可行性,对于剩余的五类二元复合开采方法,由于经济效益差、环境污染大、安全可控系数低等条件限制,目前还不具备理论可行性。提出了二元复合开采天然气水合物的理论技术思路,并通过对二元复合开采技术进行理论分析,总结出较目前常规单一开采方法具有一定理论优势的开采技术,以期为天然气水合物的稳定试采研究提供借鉴意义。
Because the conventional natural gas hydrate(NGH)mining methods are in the experimental stage, every single mining method has varying degrees of shortcomings. In this paper, a binary composite NGH mining technology was put forward. By binary randomly compositing five existing conventional mining methods, the feasibilities of the ten methods after the combination were analyzed from several aspects of technology, economy and environmental safety. The results showed that,the thermal recovery combined with the buck method, the thermal recovery combined with the ground decomposition method, the thermal recovery combined with replacement method, the injection inhibitor combined with the ground decomposition method, the injection inhibitor combined replacement method, had good theoretical feasibility;However, the other five kinds of binary composite mining methods had no theoretical feasibility due to poor economic efficiency, environmental pollution and low safety control coefficient. And then the theoretical and technical ideas of binary compound mining NGH technology were put forward, and the theoretical analysis of binary composite mining technology was carried out, the current single mining methods with certain theoretical advantages were summed up, which could provide reference for the stable trial mining of NGH.
