Log Interpretation of Horizontal Well in Anisotropic Reservoir Based on Wire-line Resistivity Logging
摘要
Abstract
Resistivity is a critical formation parameter in reservoir logging evaluation.In horizontal wells, the apparent resistivity is usually affected by the anisotropy of the formation and cannot reflect the true resistivity of the formation, and thus the reservoir parameters cannot be accurately calculated.In order to solve the problem, "double rock electrical parameters"is proposed for evaluation of anisotropic reservoir in horizontal well with conventional resistivity logging.For the target layer of the study area, the cores in the horizontal and vertical directions were taken and their corresponding rock and electric parameters were measured.Then, based on the anisotropy theory, the corresponding horizontal resistivity and vertical resistivity were calculated.Finally, the corresponding saturation was calculated by the Archie formula.The results show that the horizontal and vertical saturations are nearly close and consistent with the saturation results of the corresponding guide well or vertical section.This method has agood practical application effect for horizontal well logging evaluation with only conventional resistivity logging.关键词
