摘要
本文给出了利用双频介电测井与深侧向洲井的电阻率径向变化规律求含水饱和度的方法,导出了新的求含水饱和度的公式;结合南阳油田判断油层、水层、水淹层以及求剩余油饱和度的实例,评价了这一方法的应用效果与特点。
A new method for determination of radially changing characteristics of resistivity measurements from dual—frequency dielectric log and deep lateral log. And equation is derived. The method is used in Nanyang Oilfield to identify oil- and water—bearing formation, water—out zone and to determine residual oil saturation. This method is appraised with field examples and its advantages are also discussed.
