| Abstract: | In the reservoirs of Qigu Formation in Wellblock Che2,clay minerals are relatively higher,and it has the character of strong water sensitivity and low resistivity oil production.The cause of low resistivity oil production is analyzed,models for oil saturation interpretation are introduced in variable formation water resistivity and a chartboard for reservoir recognition is introduced into R_w/R_t parameters,by which the problem of "low resistivity reservoir" recognition is solved. |

| Keywords: | strong water sensitivity variable formation water resistivity R_w/R_t parameter low resistivity reservoir recognition |
