滨南油田低阻油层测井识别方法

Well Logging Recognition Method of Low-Resistivity Oil Bearing Zone in Bin-Nan Oil Field

储层电阻率的高低不仅与储层的含水饱和度有关,而且还与储层的孔隙度、岩性及岩性的粗细有关。以中子、密度、声波为基础,进行地层岩性识别、及岩性粗细判断,有利于低阻油层的识别与评价,应用效果良好。

Height of resistivity in reservoirs is not only related with water saturation of reservoirs,but also related with porosity,lithology and crudeness or fineness of lithology.Based on neutron,density and acoustic wave well logging,lithology recognition of formations is done and crudeness or fineness of lithology is determined which is beneficial to recognition and evaluation of low-resistivity oil bearing zones.Effect of application is good.
