摘　　要：曲线重构是提高储集层与围岩速度差异不明显地区测井约束地震反演效果的有效技术。在胜利油田埕岛地区新近系测井约束反演处理和储集层综合描述中,经过曲线重构,由于更多的地质信息参与反演处理过程,提高了应用反演结果进行储集层描述的可靠性。利用该反演结果,结合地质认识和实际的钻井、测井资料,共综合描述主要含油层系的砂体6个、预测砂体2个。反演工区内的钻井及试油资料证实了其埋深、厚度及分布范围,说明曲线重构技术在反演处理中起了有效的作用。The log rebuilding is a valid technology in improving the seismic inversion result of log constrained inversion for the areas with small velocity differences between the reservoir and the neighboring rock. The log rebuilding of the log constrained inversion and the integrated reservoir description has been made in Chengdao, Shengli Oilfield, and the liability of reservoir description has been improved by adding geological information in the course of inversion. The inversion results, together with geology recognition, actual drilling and logging information, have been used to describe 6 sand bodies and predict 2 sand bodies in main hydrocarbon layers. The drilling and formation testing confirmed its buried depth, thickness and distribution range.
