摘要
Abstract
The imaging of marine reservoir at Changxing-Feixianguan Formation in the Northeastern Sichuan basin is difficult, which is not only impacted by the complex surface seismic-geologic conditions, but also influenced by saline deposit of Jialinjiang Formation. The techniques was discussed on how to perform reservoirs imaging influenced by saline deposits from the aspects of optimization of basic data, stack imaging, poststack migration and prestack migration. Meanwhile, the disadvantages of prestack time migration and poststack migration processing were analyzed. The result indicates that prestack depth migration is the most effective method for accurate reservoir imaging while removing the impact of saline deposit. Actual application reflects abundant and reliable geologic information of the reservoirs, which provides high-quality data for lithology identification and reservoir prediction.关键词
