海洋拖曳式γ能谱仪在渤海的应用

The Application of the Marine Towed Gamma-Ray Spectrometer in Bohai Ocean

为了加快我国海洋矿产资源勘探与开发,研制了中国第一台海底拖曳式多道γ射线能谱仪,并在渤海地区进行了初次用于勘查油气田的测量试验,结果表明:仪器可以在现场测量海底沉积物、岩石等的天然放射性核素铀、钍、钾(40K)的含量,在已知油气田上方放射性核素的含量出现相对低值异常,本方法具有现场、快速和经济的特点.

In order to speed up the marine mineral exploration of China, the first sea-bed towed gamma-ray spectrometer was developed and it was tested in Bohai Ocean for oil exploration for the first time. The results show that the concentration of ^238 U, ^232Th, ^40K of rocks and unconsolidated sediments on the sea floor can be acquired in-site. There is a relative low abnormity in the known oil field. It is a rapid and cheap in-site method to explore the marine resource.
