Abstract:There are some perfect methods for researching into structure and reservoir by analysing geophysical data, however, people have been seeking for desirable methods for probing into hydrocarbon-bearing system. Hydrocarbon bearing system involves hydrocarbon migration, barrier layer, key hydrocarbon-deaerated period, hydrocarbon accumulation and so on. The compaction curve of mud formation may reElect the law of hydrocarbon migration, and the poorly-compacted interval of mud formation usually corresponds to low velocity anomaly. Hydrocarbon sealing characteristics of barrier layer can be known by analysing its inner abnormal pressure, which can be shown by the abnormal variation of seismic velocity. Seismic data can also be used to ascertain key hydrocarbon-deaerated period and hydrocarbon accumutation. The Wuerxun and Beier depressions in the Hailaer basin are taken as the examples to indicate the possibility of analysing the hydrocarbon-bearing system by using seismic data.
