Abstract: Through the study of occurrences,reservoir properties,and oil-bearing properties of tens of igneous rock bodies discovered in Tertiary in Huanghua Depression,it is concluded that igneous rocks in this area are mainly consisted of extrusive and intrusive facies,and distributed in the south,middle and north.The age of igneous rocks become older from the south to north. Different igneous rocks have different geophysical responses,which can be used as identification marks.The formation of igneous rocks are connected with basin structure movement,oil-gas generation,migration and accumulation.Six types of igneous rock reservoirs have been discovered in this area.This research will be a reference for the exploration of igneous reservoirs in this area.

Key words: Huanghua Depression, igneous rock, lithofacies, geophysical response characteristic, reservoir

摘要： 通过对黄骅坳陷第三系已发现的数十个火成岩体的产状、岩相、储集性能及其含油气性分析,初步总结出本区火成岩的类型主要包括喷出相和侵入相,岩性为单一基性岩,其空间分布以南区为主,中北区次之,时代从南到北呈现由老变新的趋势.不同类型火成岩相的地球物理响应特征不同,可作为火成岩相的识别标志.本区火成岩活动与盆地演化、油气生成、运移、聚集有着密切的关系,发现了6种与火成岩有关的油气藏.研究成果对本区火成岩油气藏勘探起到了一定参考作用.
