摘要
用常规地震解释方法进行构造解释时.断层的识别以及全区的构造特征难以把握。而三维相干体技术采用相邻道地震信号的相似性来识别断层平面分布方面非常有效。应用三维相干数据体切片进行构造解释可帮助解释人员迅速认识整个工区断层的整体空间展布特征,从而达到提高解释速度及精度,缩短勘探周期的目的。选用discover软件中的构造解释模块,应用三维相干技术对胜利油田桩241、242块进行精细构造解释,在小断层识别及整个构造闭合方面取得了较好的应用效果。
When the normal seismic interpretation method is used to interpret structure, the fault identification and structure characteristics in whole area are not sure. But it is very effective for three-dimensional coherence cube to adopt the adjacent- channel seismic signal conformability to identify fault flat distribution, By using three-dimensional coherence cube section, the interpretation personnel can carry on the structure interpretation to speedily know the space distribution characteristics, ensuring that the structure interpretation is speed and accuracy and the exploration cycle is shortened. This paper chooses to use the structure interpretation module in Discover Software and the three-dimensional coherence cube technique to carry on fine structure interpretation in Fault Blocks 241 and 242 of Shengli Oilfield, which has obtained a good effect in small fault identification and the whole structure closing.
