天然气水合物是由水分子和天然气分子在一定温度和压力下形成的具有笼状结构的似冰雪状结晶化合物。随着我国国民经济的迅猛发展,能源消耗的迅速提高和我国以煤炭为主的能源消费结构,都将导致严重的环境问题。这就迫使我们必须大力开发和应用新型可替代能源,保持能源的可持续发展。天然气水合物被认为是21世纪潜在的新能源。因此,天然气水合物对缓解我国能源短缺危机,保障国家能源战略安全和国民经济健康稳定发展都无疑具有重要的战略意义。本文主要阐述了天然气水合物赋存地层钻井液的使用原理及发展现状。
Natural gas hydrate is an ice-like crystalline compound with a cage-like structure formed by water molecules and natural gas molecules under a certain temperature and pressure. With the rapid development of our national economy, the rapid increase of energy consumption and the energy consumption structure dominated by coal in our country will lead to serious environmental problems. This forced us to vigorously develop and apply new alternative energy sources to maintain the sustainable development of energy sources. Gas hydrates are considered potential new sources of energy in the 21st century. Therefore, natural gas hydrate has undoubtedly important strategic significance for alleviating the crisis of energy shortage in our country, ensuring the safety of national energy strategy and the healthy and stable development of national economy. This paper mainly expounds the use principle and development status of drilling fluid for gas hydrate-bearing strata.
