以层序地层学理论为指导,充分应用现代地震勘探新技术(主要指高分辨率地震、多属性提取、三维可视化透视显示、相干体分析、测井约束反演、储层横向预测等技术),形成了一套识别和描述隐蔽圈闭的技术系列,并在JH凹陷八块三维地震解释中找到了一批有利隐蔽圈闭,在综合评价的基础上提供钻探目标一个。

Guided by the theory of sequence stratigraphy, a suite of techniques for identification and description of subtle traps have been developed based on modern new technologies of seismic exploration such as high resolution seismic, multi attribute extraction, 3 D visualization, coherence analysis, well constrained inversion, reservoir lateral prediction. A number of subtle traps have been found during the 3 D seismic interpretation on data from eight blocks in JH sag. A drilling target was determined after comprehensive evaluation.
