侵入岩的地震信息识别及其与油气的关系
摘要
近年来,随着常规油气藏勘探难度和勘探风险日益增大以及火山岩油气藏的不断发现,火山岩油气藏作为油气勘探的一个新领域,已引起了石油界的普遍关注和高度重视。以往的研究大多集中在研究喷发岩的地震信息识别及其与油气的关系,研究侵入岩的地震信息识别及其与油气的关系具有重要的理论与现实意义。通过对典型地震剖面的研究,识别出了岩株、岩盖、岩床和岩墙4种产状的侵入岩岩体,阐明了它们的地震信息识别特征,同时分析了不同产状的侵入岩与油气的关系,论述了8种与侵入岩有关的油气圈闭类型。
In recent years,the difficulty and risk have increased in exploration for the conventional petroleum.With the continuous discovery of the volcanic reservoirs,volcanic-related rock reservoirs have become a new field of hydrocarbon exploration,and have greatly attracted the attention of the petroleum geologists.Former researches mostly focused on the seismic character identification of extrusive igneous rock and extrusive igneous rock-related reservoirs,therefore the study of seismic character identification of intrusive igneous rock and intrusive igneous rock-related reservoirs has an important theoretical and practical meaning in hydrocarbon exploration.Through the comprehensive research of the typical igneous seismic profiles in Qiongdongnan basin,the stocks,laccoliths,sills and dikes were identified from other seismic characters,and their identification characters were also summarized.Finally by the analysis of their implications for hydrocarbon systems,eight kinds of intrusive igneous rock-related traps were proposed.
