【摘要】 高效天然气藏的成藏条件有别于大中型气藏,其形成需要同时具备高效的气源灶、高效的成藏过程和高效的储盖能量配置。指出琼东南盆地崖13-1构造新近纪以来地层沉降速率快、沉积厚度大,潜在气源岩在短时间内大面积进入了生、排烃高峰阶段,普遍发育的动态型超压系统为含气流体初次排放和在三维输导体系中二次垂/侧向运移提供了有效动力,储层常压和盖层超压这种有利的储盖能量配置关系是气藏得以保存的重要因素,认为崖13-1气藏是晚期超压环境下快速充注、生-储-盖“黄金”配置、立体输导型高效天然气藏。更多还原

【Abstract】 The accumulation environment of the efficient natural gas reservoirs are differ from large-medium sized,which require simultaneously efficient gas source rocks,accumulating process and energy match of reservoir rocks and cap rocks.Due to fast subsidence rate and great sediment thickness in Ya13-1 structure zone Qiongdongnan basin from Neocene to this day,the large area gas source rocks rapidly came into generation/migration phases.Universal dynamic overpressure afforded stronger power for liquid migration in 3D conduit system.The reservoir sandstones are normally-pressured and the cap rocks are overpressured,and such favorable energy match relation is very important for gas reservoirs conservation.Ya13-1 gas field is a late,overpressure,fast charge,3D carrier and ideally energy match,efficient natural gas reservoir.更多还原
