摘要
Abstract
In order to find residual oil of Gudao Oilfield Ng group in Shengli oil/gas zone, formation water resistivity, especially, flooded formation water resistivity needs to be accurately calculated. It is difficult to accurately calculate mud filtrate resistivity. Proposed is a new method to determine mud filtrate resistivity--known water layer calibration method. Based on the spontaneous potential logging principle, wellbore mud filtrate resistivity is calibrated with known water resistivity. With the calibrated mud filtrate resistivity, spontaneous potential can be applied to obtain the formation water resistivity of the target layers. The new method can accurately calculate the formation water resistivity even in water-flooded zones.关键词
