航空重磁综合测量在准噶尔油气资源调查中的应用

为满足油气资源调查需要、查明准噶尔盆地基底结构、提供新的油气有利勘探区,中国国土资源航空物探遥感中心在准噶尔盆地中西部开展了航空重磁综合调查。通过项目实施,在国内首次实现了航空重磁综合测量,共采集大比例尺(1:5万)高质量航空重磁数据6.6万测线公里,填补了调查区内大比例尺高精度航空重磁资料的空白,查明了调查区内航空重力场与磁力场特征,为开展基础地质研究和油气资源评价提供了重磁依据,夯实了航空重磁联合测量和综合地质应用研究的基础。

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.
