东濮凹陷下第三系地层具有多物源、近物源的沉积特点,横向岩相变化快、沉积体系类型多,地层主要为砂泥岩薄互层沉积。通过深层地震正演模拟,开展深层地震勘探方法研究,总结不同类型沉积砂体地震识别优势技术,改进地震处理方法,提高地震资料品质,为深层油气藏勘探提供可靠的依据,对中原油田持续稳定发展具有十分重要的理论和现实意义。
The Lower Tertiary strata in Dongpu Depression have the sedimentary characteristics of multi-source and near-provenance, the lateral facies changes rapidly, and the types of sedimentary systems are numerous. The strata are mostly interbedded with sand-shale thin interbed. Through deep seismic forward modeling, deep seismic exploration methods are studied, and the advantages of different types of sedimentary sand body seismic identification technology are summarized, seismic treatment methods are improved, seismic data quality is improved, and reliable basis for deep reservoir exploration is provided. Development has very important theoretical and practical significance.
