摘要
对曲堤油田沙河街组低电阻率油层的形成机理进行了研究 ,认为主要成因是粘土的附加导电性和粘土吸附水和自由水之间的离子交换的影响 ;利用 S- B电导率模型对该油田低电阻率油层含水饱和度进行了解释处理 。
The mechanism of low resistivity pay zone in Shahejie group of Qudi oilfield is studied in the paper. It is believed that additional conductivity of clays and ion exchange between absorption water and free water in clays are the main cause that generates such a zone. The water saturations of the low resistivity pay zone in the oilfield are processed with the S B conductivity model, the interpretation result of which is improved.
