Abstract

Based on the study of clay mineral types,characters of rock frameworks and grains,wettability of the rocks,conductance of special heavy minerals,the origin of low resistivity reservoir of Qiangjiang formation in Qiangjiang sag is identified: rock’s character of reservoir has a little infection on the formation of low resistivity reservoir;irreducible water content in the rock is the major factor;the odditional conductivity caused by mud and clay and incursion of the mud filtrate are the minor factors.

Key words： Jianghan basin; Salt bed; Low resistivity reservoir; Formation mechanism; Identification.
