通南巴地区长兴组生物礁储层预测
|
摘要
生物礁作为一类特殊储集岩体的出现,曾引起业内人士广泛关注。以地震剖面上的目标时间内波组的"丘状"、"透镜状"外形识别生物礁,以瞬时相位剖面上相位错动、畸变等特征确定生物礁边界和顶底,用时差估算礁体厚度的生物礁预测分析方法,对通南巴地区长兴组生物礁储层进行预测。
Bioherm's appearance as a special reservoir rock had attracted wide range of interests within the trade.This paper had elaborated on how to predict the location of reef reservoirs in Changxing Formation,Tonnanba district by using time differences to estimate reefs' thickness.The steps include identifying reefs through lenticular or bump-shaped wave group on seismic section within a certain period of time and determining the peripheries and height of the reefs through phase dislocation and distortion on instantaneous phase sections.
