本文根据W-F-1构造的浅层强振幅异常的特殊反射外形,从振幅、速度和频率三大参数分析出发,认为它具有烃类直接指示的地震反射特征。同时,通过对中新世时期沉积环境的分析,认为这个强振幅异常体可能为生物礁含气圈闭。

Based on the analysis made with respect to the special reflection configuration of the high amplitude anomaly of W-F-l shallow structure and 3 major parameters,amplitude,velocity and frequency.it is considered that the structure is characterized by the direct HCI (hydrocarbon indicator)seismic reflection. Moreover,by examining the Miocene deposilional environment, the anomalous body of high amplitude could be a gas-bearing reef trap.
