| 摘 要： | 北黄海盆地是中国东部勘探及研究程度较低的含油气盆地之一,多期构造活动伴生形成的大量火成岩进一步增加了北黄海盆地油气勘探工作深入的难度。为了掌握北黄海盆地某区块火成岩的空间分布特征,利用盆地近年最新采集处理的某区块三维地震资料,通过区内钻测井资料综合分析建立特有火成岩岩石物理模型,运用双参数约束三维地震叠前同时反演技术对研究区的火成岩分布进行预测。结果显示利用纵波阻抗和纵横波速度比双参数联合约束的地震叠前同时反演技术,可以对区内的火成岩进行较为有效的刻画,分析认为北黄海盆地某区块内火成岩由多期形成,中深部的火成岩主要以岩株、岩墙或岩脉状为主,具有规模小、分布广的特点。

| Abstract: | The North Yellow Sea Basin is one of the petroliferous basins with low degrees of exploration and studies in the east of China. The large amount of igneous rocks associated with multiple tectonic activities further increases the difficulties in oil and gas exploration of the basin. In order to obtain the characteristics of igneous rock distribution, using the latest acquisition and processing 3D seismic data and the newly established special igneous rock physical model through comprehensive analysis of drilling and log data, this article predicts the distribution of igneous rocks in a block in North Yellow Sea Basin with application of double-parameter constraints and seismic pre-stack simultaneous inversion. The results show that it is an effective method of prediction; the igneous rocks dominated by intrusive stocks or dykes in this area have the characteristic of small scale and wide distribution. |
