摘要
High-speed intrusion of igneous rock is widespread in the northern slope of Gaoyou Depression.The included angle of igneous rock with formation is little,presenting northeast-southwest trend substantially.Because of the igneous rock from deep part to shallow part along the slope zone from south towards north,igneous rock indicates the transverse intrusion sterically and concordant intrusion regionally,which generates a great influence on reservoir.Through the study of the effect of igneous rock on reservoir,it is believed that the igneous rock intrusion make the reservoir diagenesis accelerate,make the temperature and pressure change and create the low temperature metamorphic mineral and optalic metamorphism.Harms are greater than interest in the study from the effect of igneous rock on reservoir.
