| 摘 要： | 由于CRS叠加考虑了反射层的局部特征和第一菲涅耳带内的全部反射，从而更充分地利用了多次覆盖反射数据的信息。就目前的地震资料处理技术而言，它是最佳的零偏移距成像方式。本论文利用改进型的参数优化技术，得到高质量的CRS运动学参数剖面，并利用参数剖面计算出叠加孔径，实现了基于最优孔径的CRS叠加，使CRS参数的用途得到了充分利用。模型数据和实际资料的试算表明，基于最优孔径的CRS叠加的成像剖面与传统CRS叠加剖面相比，有着较高的信噪比和同相轴的连续性。

| Abstract: | The common reflection surface (CRS) stack is based on the local dip of the reflector and the reflection response within the first Fresnel zone. During the CRS stack all the information given by a multi-coverage reflection dataset can be successfully utilized. By now, it is known as the best zero-offset (ZO) imaging method. In this paper high quality CRS kinematic parameter sections are obtained by a modified CRS optimization strategy. Then stack apertures are calculated using the parameter sections which fi... |
