摘　　要：天然气水合物是一种极具潜力的清洁能源,水合物的安全高效规模化开发,对于缓解中国能源紧缺压力和优化调整能源结构具有重要意义。介绍了天然气水合物藏的4种开采方法以及中外开展的水合物现场试采的进展,目前水合物试采仍面临着开采难度大、产量较低和开采成本高等诸多挑战,亟须解决长期开发所要面临的增产工艺技术及经济问题。因此,重点阐述了针对天然气水合物4种常规开采方法的增产提效技术,介绍了为了提高水合物储层动用能力的井网设计及储层改造方案,为天然气水合物藏新一轮的工程试采提供借鉴。Natural gas hydrate is a clean energy source with huge resource potential.It is of great significance for the safe and efficient large-scale commercial development of natural gas hydrates to relieve the pressure of domestic energy shortages and optimize the energy structure.Four conventional production methods for natural gas hydrate reservoirs and the progress of hydrate field trial production at home and abroad were introduced.At present,hydrate trial production still faces challenges such as engineering difficulty,low output and high production cost,which need to be solved urgently.To provide a reference for the next engineering trial production of natural gas hydrate reservoirs,the production enhancement and efficiency improvement technologies for the four conventional production methods were emphasized.In addition,in order to improve the production capacity of hydrate reservoirs,well pattern design and reservoir reconstruction schemes were elaborated.
