本文以本区最早期地震工作所发现的地震低速异常为靶标．利用地震资料精细处理及岩性特殊处理的成果，结合钻井、地质、测井等资料对该地震低速异常进行了深入的跨学科综合研究。从平均速度和层速度两方面入手，掌握了本区低速异常的特征及展布规律。运用层序地层学等方法对低速异常的性质进行了分析和探讨；并运用岩性地震理论对本区地震低速异常的含油气性进行了综合评价。通过地震多参量模糊判别技术的应用，预测出本区的两块油气富集带．此项研究取得了良好的地质效果。
This paper targets the low-speed anomalies of earthquakes found in the earliest earthquakes in this area. Based on the results of the fine processing of seismic data and the special treatment of lithology, the low-speed anomalies of the earthquakes are deeply interdisciplinary comprehensively combined with the data of drilling, geology and logging. Starting from the average velocity and velocity, we grasp the characteristics and spreading law of low-velocity anomalies in this area. This paper analyzes and discusses the characteristics of low-velocity anomalies by means of sequence stratigraphy and other methods. The lithology-based seismic theory is used to evaluate the hydrocarbon-bearing properties of low-velocity anomalies in this area. By using the multi-parameter fuzzy discriminant technique of earthquake, two oil and gas enrichment zones in the area are predicted. This study has achieved good geological results.
