Adaptive Weight Multi-channel Matching Pursuit Algorithm-Based Strong Shielding Removal Method
CT Lilun yu yingyong yanjiu, 2023 The strata with large impedance differences are presented as strong amplitude seismic events on the seismic profile, which obscure useful information of nearby reservoirs and need interpretive target processing to remove the strong shielding.

A new method of alternating shooting of two different seismic sources for deep geophysical surveys
Scientific Reports, 2023 In the latest geophysical survey crossing the Ninety East Ridge of the Indian Ocean, a new method was employed to perform proportional double seismic source excitation and synchronously receive signals from the sea surface and the seabed. The two seismic

Development of a Highly Flexible and High-Resolution Deep-Towed Streamer
Journal of Marine Science and Engineering, 2019 We have developed new a deep-towed seismic streamer for sub-bottom profiling. To obtain a high-resolution seismic signal, this streamer can be operated at depths of up to 2000 m, and state-of-the-art technology is adopted with electronics circuits, that ...

Dizhen xuebao, 2019 为了实现龙门山区域地质信息的科学管理与共享，推动该区域地球物理资料的统一管理，本文在整理现有二维地球物理探测数据的基础上构造了龙门山断裂带区域的三维地壳结构模型，并结合实测的布格重力异常数据对模型进行了分析。结果表明，地层模型正演的整体重力场与实测布格重力异常基本吻合，初步证明该模型的正确性。局部重力场显示：在该模型的尺度下，沉积层对整体重力场的变化贡献较小；中上地壳有不同程度的隆起和坳陷，与前人研究所揭示的低速异常体吻合；地幔表现为规则的自西北至东南单调上升的重力异常梯度带，与前人反演结果的趋势一致 ...
