capture cross section determination是什么意思

用法例句

Element capture service (ECS) can be applied to quantitative determination of the contents of Si, Ca, Fe, S, Ti, Gd in stratum.

ECS测井是元素俘获测井的简称,它可以定量提供地层中的Si、Ca、Fe、S、Ti、Gd等化学元素的含量。

A single pass can provide 144 curves directly, including capture cross section sigma curve, formation ratio curve, far near sonde counting rate curve, total inelastic scattering gamma ray interpreted by software, and neutron, density porosity curve, which are most sensitive to the gas formation.

它一次下井可直接获得 14 4条曲线 ,其中的地层俘获截面曲线、地层比值曲线和远、近探头计数率曲线以及经过解释软件处理后的总非弹性散射伽马射线和中子、密度孔隙度曲线对气层反映最敏感。
