航空重力梯度测量作为一种高效快速和高分辨率勘探手段,在固体矿产资源勘查和油气勘探中发挥着日益重要的作用.目前,商用部分张量航空重力梯度测量系统和研制中的一下代超导航空重力梯度测量系统仅能测量重力梯度张量中的部分张量分量或分量组合,不利于后续地质解释和测量成果应用.本文基于重力位微分的频率域通用公式,针对Falcon部分张量重力梯度测量系统,以重力位为纽带,建立了重力梯度张量分量频率域转换公式,实现了基于平面观测数据的重力梯度张量分量快速转换处理算法,通过理论模型试验证明了算法的正确性和有效性.
As an efficient, rapid and high-resolution exploration method, airborne gravity gradient measurement plays an increasingly important role in solid mineral resources exploration and oil and gas exploration.At present, the commercial partial tensor airborne gravity gradient measurement system and its development in the generation of super The navigation empty gravity gradient measurement system can only measure part of the tensor component or combination of components in the gravity gradient tensor, which is not conducive to the subsequent geological interpretation and application of the measurement results.Based on the common formula of the frequency domain of the gravity differential, System, the gravity field as a link, established the gravity gradient tensor component frequency domain conversion formula, based on the observed data of the plane to achieve a rapid gradient gravity gradient component conversion algorithm, the theoretical model tests prove that the algorithm is correct and effective .
