地震综合解释技术在地层超覆圈闭研究中的应用

Application of Integrated Seismic Interpretation Technique in Studying Stratigraphic Overlap Trap

地层超覆圈闭的识别和描述是勘探工作的难点,在XYX地区运用地震综合解释技术对地层超覆圈闭进行了探索性研究。通过成藏条件分析,总结出该区地层超覆圈闭成藏模式;在成藏模式的指导下,运用层位标定、地震资料精细解释和STRATA地震反演技术对圈闭进行识别和描述。根据研究结果,在该区地层超覆圈闭上钻探了陆2井,实钻证明该技术应用效果良好。

Identification and description of stratigraphic overlap trap are the difficulties of exploration. Stratigraphic overlap trap in XYX Region is approached by using integrated seismic interpretation technique. Through analyzing reservoir forming conditions, its forming mode of the stratigraphic overlap trap in the region is established. Under the guidance of the mode, the trap is identified and characterized by using horizon definition, seismic data precised interpretation and STRATA seismic inversion. According to the research result, two wells are drilled in the overlap trap, by which the technique is proven with good result.
