Abstract

Crooked-line seismic survey has been widely used in oil and gas exploration in complex areas of western China. However, due to the unconventional acquisition geometry, current migration methods cannot fully account for the characteristics of crooked-line seismic data and may lead to poorly-resolved images with inaccurate kinematics. To mitigate this problem, we present in this paper a modified Kirchhoff prestack time migration well adapted to crooked-line seismic data. We first carry out a theoretical analysis on the propagation geometry of crooked-line seismic data and demonstrate problems associated with conventional 3D traveltime-based migration. Then, we present a modified 2D migration scheme based on the projection between the actual imaging trace within the vertical plane of seismic reflections and the output imaging trace. Compared with the 3D traveltime-based migration, our method not only ensures the accuracy of imaging depth but also improves the focusing and continuity of the migrated image. We use both synthetic and real data tests to validate the correctness and effectiveness of the proposed method.

歪线地震数据的基尔霍夫预叠加时间迁移
歪线地震勘探已广泛应用于中国西部复杂地区的油气勘探。然而,由于非传统的采集几何形状,目前的迁移方法无法完全考虑歪线地震数据的特征,可能导致分辨率低、运动学不准确的图像。为了缓解这一问题,我们在本文中提出了一种改进的 Kirchhoff 预叠加时间迁移方法,该方法非常适合歪线地震数据。我们首先对歪线地震数据的传播几何进行了理论分析,并展示了与传统的基于三维行进时间的迁移相关的问题。然后,我们提出了一种基于地震反射垂直面内实际成像道与输出成像道之间投影的改进型二维迁移方案。与基于三维行进时间的迁移相比,我们的方法不仅确保了成像深度的准确性,还改善了迁移图像的聚焦性和连续性。我们通过合成数据和实际数据测试来验证所提方法的正确性和有效性。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
