中文摘要：

综述了重磁数据三维物性反演方法中的几个关键问题.主要包括正演快速算法、反演框架、约束因子讨论、反演算法实现等方面.正演快速算法主要讨论了等效存储几何格架技术、基于GPU加速的并行计算技术以及小波压缩技术.三维物性反演则是在最小二乘意义下使目标函数达到极小的线性或非线性反演.指出,对于特定地质问题需要谨慎选择不同且合适的约束方法乃至反演算法,才能达到好的效果.最后讨论了重磁数据三维物性反演较好的应用前景及发展方向.

英文摘要：

In this paper,we review several main issues in 3D property inversion of gravity and magnetic data,including fast forward calculation algorithm,inversion framework,constrained factors and inversion algorithms.The method of equivalence storage of prisms,parallel computing based on GPU and wavelet compression are discussed.3D property inversion means linear or nonlinear inversion that minimizes the objective function.Meanwhile,appropriate constraints with different geological problems should be considered in order to obtain good results.Finally,we discuss the application prospects and development direction of 3D property inversion of gravity and magnetic data.
