重力全梯度张量的延拓
THE CONTINUATION OF THE GRAVITY GRADIENT TENSOR
摘要
Abstract
We proved that gravity gradient tensor is satisfied with Laplace equation and implement the continuation calculation of gravity gradient tensor based on Fourier transform. The results of three-dimensional fault model show that the calculation of upward continuation is theoretically rigorous and can be implemented. The calculation error is mainly due to the limited integration range, the higher the height of upward continuation the higher the error. The downward continuation of gravity gradient tensor is an ill-posed problem. Usually, there will be a serious oscillation phenomena, leading to helpful gradient tensor information drowned while the height of downward continuation is greater than three times dot spacing. We verified the practicality of the continuation of gravity gradient tensor by the real data of Heilongjiang province Hulin basin.关键词
