Study on Acoustic In-situ Measurement Method of Marine Bottom Sediment and Application in Detection of Hydrates in the South China Sea
Pages: 109-113
Year: Issue:  4
Journal: Ocean Technology

Abstract: 研究原位测量技术中表层沉积物声学原位测量技术、声波测井技术和OBS测量技术的特点和差异,得出3种技术的分辨率虽然依次降低,但测量尺度依次增大,可以应用不同深度和结构层序的海底沉积物声学物理性质研究.3种原位测量技术基于海底原位状态,可以测得海底沉积物的纵波和横波特性,通过比较纵波特性、纵横波速比和计算泊松比可以提高沉积物中分辨出天然气水合物的精度.基于OBS测量技术可以同时实现水合物的勘探与监测,...
