本文回顾了莺—琼盆地勘探状况。该地区在地震剖面上有一个令中外地质学家瞩目的巨大振幅异常体, 历经十六年的分析、落实, 已钻三口井, 但仍然是一个猜不透的谜, 反映了常规地震勘探方法的某些局限性。本勘探实例应用了储层物性参数处理技术的成果, 初步揭开这个勘探目标的“面纱”, 说明该技术有助于隐蔽油气藏的查找。

In the paper we review the exploration situation in the Yinggehai-Qiongdongnan basin. A huge amplitude anomaly which is the attention focus of geologists in China and abroad exists in seismic sections in this area. Through the efforts of 16 years, three wells have been drilled, but the enigma is yet not fathomed. This reflects that the conventional seismic methods have some limitations. In the exploration case presented in the paper, we use technological achievements for reservoir physical parameters processing and tentatively reveal the details of the exploration target. This shows that these techniques are helpful to search hidden oil and gas reservoirs.
