海洋天然气水合物储层敏感性研究进展
Research progress on sensitivity of marine gas hydrate reservoir
摘要
Abstract
Natural gas hydrates represent a promising alternative energy source,with numerous experimental ex-plorations conducted internationally.The permeability of natural gas hydrate reservoirs is a key parameter affect-ing the gas recovery.Due to the shallow burial depth and poor consolidation characteristics of hydrate reservoirs,their permeability is affected by various factors during extraction,which is termed permeability sensitivity.Tech-niques for testing the permeability of hydrate reservoirs were introduced.The mechanisms underlying permeabil-ity sensitivity,specifically stress sensitivity,flow velocity sensitivity,water sensitivity,and salinity sensitivity,were analyzed.Theoretical models describing permeability sensitivity in hydrate reservoirs were summarized.Ex-isting problems in the study of hydrate reservoir sensitivity were outlined,along with suggestions for future re-search,to provide references for natural gas exploitation.关键词
