求翻译：而氯原子对热中子的吸收截面又比地层流体（水、油）中的主要元素原子（C、H、O）的截面大很多倍，这样，含水层的总截面将明显大于含油层截面。是什么意思？

Chlorine atoms on the thermal neutron absorption cross section off than formation fluid (water, oil) in the cross-section of the main elements of the atom (c, h, o) many times, so that the total cross section of the aquifer will be significantly greater than the oil layer cross-section.

And chlorine atoms in the thermal neutron absorption cross-sections, and laminar flow (water, oil, the main element, atomic (C H O), the large cross-sectional area, many times in this way, the aquifer will be significantly larger than the cross-sectional layers cross-sections.

But chlorine atom to thermal neutron absorption cross-section formation fluid (water, oil) principal element atom (C, H, O) the section are greatly very more than time, like this, the water-bearing stratum total cross-section obviously will be bigger than the oil-bearing formation section.

Chlorine atom absorption cross section for thermal neutrons than formation fluid (water and oil) major elements in Atom (c, h, o) section many times larger, so that the total cross section of the aquifer will be significantly larger than the oil section.
