Abstract：A reservoir can be ascertained by using borehole-surface DC resistvity gradient measuring method that takes the whole borehole casing as an electrode. In the situation where there are rather shallow structural reservoir. gentle variation of surrounding resistivity and quite flat surface.this method can be well used to determine the boundary.top point and occurrence of a reservoir.to perform vertical or lateral reservoir prediction.and to monitor reservoir production.etc.
