| 摘 要： | 利用北黄海盆地某区块最新采集处理的三维地震资料,通过钻、测井资料综合分析建立井震关系。使用地震相分析、叠前反演以及多属性综合预测等技术刻画火成岩的形态和空间展布特征,总结本区火成岩在地震剖面上的响应特征及空间变化规律。综合预测结果显示研究区内东部发育有规模巨大的潜山型火成岩,西北部发育有侵入岩体刺穿,其他区域主要发育小规模岩株、岩墙或岩脉状侵入岩。

| Abstract: | In this study, the special well-seismic relation has been established on the basis of comprehensive analysis of newly acquired and processed 3D seismic data in a block of the North Yellow Sea Basin, and drilling and logging data of wells. Seismic facies analysis, pre-stack simultaneous inversion and multi-attribute analysis were used to identify and predict the geometry and spatial distribution of the igneous rocks. Seismic response of igneous rock was characterized. The results show that there exist a series of large buried-hill-type igneous rocks in the east, a typical piercing igneous rock mass in the northwest, and some small scattered intrusive stock or dyke in other areas of the studied area. |
