国内外水溶气开发技术现状及发展建议

The Current Situation and Suggestions for Water-Soluble Gas Development Technology at Home and Abroad

  • 摘要: 水溶性天然气(简称水溶气)是一种储量巨大的非常规能源,极具开发潜力和发展前景,但目前缺少系统的理论研究,也没有成熟的开发技术。详细介绍了国内外水溶气的储量分布及开发现状,总结了国内外水溶气开发技术研究的主要进展,主要包括地热型水溶气开采与二氧化碳地质封存结合技术、采出水回注技术的基本原理及现场试验情况,以及对气水界面和水侵规律的影响研究结果。分析认为,目前水溶气开发技术研究虽然取得一定的成果,但未形成系统的理论体系,也没有形成综合利用、经济有效和安全可靠的开发技术。为此,需高度重视水溶气勘探开发技术研究,以实现我国水溶气的有效勘探开发,为保障国家能源安全提供新的思路。

     

    Abstract: Water-soluble natural gas (referred to as water-soluble gas) is a kind of unconventional energy resource with huge reserves, presenting considerable development potential. However, systematic theoretical research and mature exploitation technology of it are still lacking. The distribution and exploitation status of water-soluble gas reserves at home and abroad are introduced in detail in this paper. In addition, the main research progresses in technologies for developing water-soluble gas are summarized, including the basic principle and field test of the technology combined geothermal water-soluble gas extraction and carbon dioxide geological storage, and the technology of produced-water reinjection. Following that, the research results of the influence of gas-water interface and water invasion law are also presented. According to the analysis, although the researches on water-soluble gas development technology have achieved some success, corresponding systematic theoretical system and economical, effective, safe and reliable development technology capable of comprehensive utilization are still yet to be formed. Therefore, it is necessary to attach great importance to the research on the exploration and development technology of water-soluble gas to enable the effective exploration and production of water-soluble gas in China and provide new ideas for safeguarding national energy security.
