摘要:
 天然气水合物试采期间,储层分解可能导致井筒失稳,井筒中水合物的二次生成易造成管柱堵塞、套管破坏、井喷等生产事故。基于1965年前苏联陆地冻土天然气水合物试采到我国南海海域天然气水合物试采所取得的成果,分析了热注法、降压法、化学剂注入法、气体置换法等试采方法的原理、应用及其优缺点,同时介绍了近年水合物试采实验研究新方法新理论。分析表明,降压法是目前水合物试采中最成熟的试采方法,建议与其他试采方法联合使用,进一步提高天然气水合物的试采产量。
Abstract:
During the production test of natural gas hydrate, the decomposition of reservoir may lead to the instability of wellbore, and the regeneration of hydrate in wellbore may cause the string blockage, casing damage, blowout and other incidents. Based on the production test results of natural gas hydrate from the land permafrost of the former Soviet Union in 1965 to the South China Sea, this paper analyzed the principle, application, advantages and disadvantages of the production test methods such as heat injection, depressurizaiton, chemical injection and gas displacement, and introduced the new method and theory used in the experimental study on production test of natural gas hydrate in recent years. The analysis results show that the depressurization is the most mature method for production test of hydrate. It is suggested to use the depressurization in combination with other methods, so as to further improve the testing production of natural gas hydrate.
