Abstract:In order to obtain the basic data of aerogeophysical survey and provide some reference for hydrocarbon resources survey and evaluation in Tuquan Basin, China Aero Geophysical Survey and Remote Sensing Center for Land and Resources carried out the 1:100 000 airborne gravity and magnetic survey in this area. Based on the latest airborne gravity and magnetic data and measured petrophysical data, the authors studied the gravity and magnetic anomaly characteristics of Tuquan Basin and its adjacent areas, analyzed the relationship between airborne gravity and magnetic anomalies and stratigraphic distribution, faults movement and igneous rocks distribution, and mainly discussed the characteristics of basin basement. The results show that the airborne gravity and magnetic anomalies of the study area have obvious regularity in the intensity, distribution range, shape, gradient and strike. The distribution of fault system in this area has obvious correlation with gravity and magnetic field characteristics. The NNE-NE trending, NW trending and NE trending of fault structures have obvious controlling effects on the basin sedimentary and igneous rocks distribution. The basin basement should be composed of low-grade metamorphic rocks of Lower Paleozoic and moderately metamorphic rocks of Prepaleozoic.
