Application of comprehensive airborne gravity and magnetic investigation in oil and gas resources survey in Junggar Basin

China Aero Geophysical Survey and Remote Sensing Center for Land and Resources carried out a comprehensive investigation on airbone gravity and maganetic in the midwest of Junggar Basin for the first time to serve oil and gas resources survey, find out the base structure of Junggar Basin and provide new favorable oil and gas exploration area. With high quality 1:50 000 gravity data of 66 000 km, this study has filled a research gap of high-precision airborne gravity and magnetic exploration in this investigated areas. The features of gravity field and magnetic field have also been investigated in the study areas, providing gravity and magnetic basis for fundamental geology study of oil and gas resources assessment and building a solid foundation for the study of comprehensive gravity and magnetic investigation and the application of integrated geology.
