摘要
页岩气藏属于典型的低渗透率、低孔隙度的非常规天然气藏,并且在全世界资源分布广泛。页岩气作为一种新兴能源,其资源潜力是巨大的,但由于其特殊的地质条件,常规的开发技术无法直接适用于页岩气藏的生产。页岩气藏能够成功开发的关键在于压裂技术的进步,在页岩气开采过程中,水平井分段压裂和清水压裂、重复压裂、同步压裂等技术的应用,大大提高了页岩气藏的产气量。此外分析了我国页岩气的资源现状及研究前景,建议应在借鉴国外先进经验的基础上大力加强理论研究和技术创新。
Shale gas reservoirs are an important part of unconventional gas production,which is characterized by ultra low permeability and porosity,it spread all over the world.As an emerging energy,shale gas has a huge resource potential,but it's very difficult to deal with the reservoir exploitation,because conventional exploitation technology is unsuitable for shale gas play.The economic recovery of gas from shale reservoirs requires optimal hydraulic fracturing technology in horizontal wells.As for the hydraulic fracturing technology,it refers to multi-stage hydraulic fracturing,slickwater fracturing,refracturing,simultaneous fracturing.The paper also discuss the current statement and prospect of china shale gas resources,and we should do more theory research and technology innovation at the basis of learning from foreign advanced experience.
