| Abstract: | 3-Resistivity overlying method is discussed in this paper. By applying the overlying of measured formation resistivity, calculated resistivity of water-bearing zones, and critical resistivity of oil-bearing zones, the accuracy of interpretation to discriminate between oil-and water-bearing zones in shaly sand section is improved.The examples of application to the oilfields indicated that 3-resistivity overlying method can not only effectively distinguish between oil-and water-bearing zones in sand and shaly sand formations, and calculate the effective water saturation of oil-bearing zones, but also effectively identify oil-and water-bearing zones in calcareous sand formation. |
