摘要
Abstract
Prestack migration strongly relies on the geometry, and the geometry with good attributes can effectively improve the result of prestack migration. However, at present, there are few geometry design and demonstration methods based on the pre-stack migration imaging effect in the high-precision seismic exploration. Therefore, we introduced the geometry design method from the requirements of pre-stack migration imaging. Firstly, we analyzed the impact of the selection of geometry parameters (such as trace distance, shot point distance, receiving line distance, shot line distance and maxi mum offset) on pre-stack migration. Then, double focusing, prestack migration response and foot print analysis technology were u-tilized to reasonably select geometry parameters. The application of the method acquired good result in the Shinan block of Shengli ex ploration area.关键词
