摘　　要：L气田位于南海西部深水区域,由于该气田钻井较少,优质砂体分布位置处于海底坡折带转折端,水深变化异常剧烈。受海底坡折带影响地震资料品质差,地震主频及分辨率均较低,地震资料的振幅属性与含气范围存在明显不一致,振幅属性对含气性指示关系差。这些因素导致本气田储量计算中含气面积、厚度等关键参数落实难度大。针对上述问题,开展了针对海底坡折带储层及含气性定量化正反演等关键技术研究,较好地解决了气田储量研究中的地球物理难题,为储量合理计算提供有力支持。The L gas field is located in the deep-water area of the western South China Sea.Due to limited drilling,high-quality sand bodies are distributed at the turning point of the seabed slope break,and the water depth changes abnormally dramatically.There are other uncertainties have also made the gas volume calculation problematic,which include poor seismic quality,low main frequency and bad correlation between seismic amplitude and gas-bearing properties.Concerning the foresaid issues,multiple key technologies study have been conducted like reservoir property quantifying forward modeling and reversion,etc.They’ve provided a sound base for further gas volume evaluation.
