英文摘要The latest seismic interpretation suggests the presence of several igneous intrusions in the Changchang Sag, Qiong dongnan Basin, South China Sea. A 2-D geothermal modeling based on the finite element method (FEM) has been performed to analyze the thermal effect of the three intrusions of different scales distributed in the same seismic line. The organic maturity change for the Yacheng Formation caused by intrusions was demonstrated by artificial wells 2 km and 5 km away from each igneous body in combination with the acquired paleo-geothermal field and the Easy%Ro model. The results indicate that the temperature of igneous bodies dropped down rapidly during the first 1 Ma after the intrusion and cooled down to nearly the same temperature as that of the wall rock after 10 Ma. The biggest intrusion caused a theoretical vitrinite reflectance (Ro) 1.6% higher than normal for the Yacheng Formation at a distance of 2 km away from it and only 0.4% higher at a distance of 5 km.
