求翻译：针对低孔低渗碎屑岩储集层测井评价中存在的问题，在国外Givens[12]、Brown[13-14]、Crane[15]等学者提出的综合导电模型基础上，结合研究区低孔低渗储集层孔隙结构特点，笔者提出了一种改进的、简单适用的、基于孔隙结构的饱和度模型，即双孔隙饱和度模型，并给出了模型中各参数的确定方法，旨在提高低孔低渗碎屑岩储集层含油气性定量评价的准确性。是什么意思？

This example showed, in identical reservoir, because if the lothological change causes the reservoir nature to have the difference, if this time the reservoir electric properties change is not big, then to the lothological thinning natural variations stratigraphic interval, must lower some with the
