Method for obtaining information indicative of a resistivity of formation, means readable by processor is not transient, method for correction of measurement of conductivity of the formation.The apparatus and medium readable by the processor

摘要

Apparatus and methods are described, for example for obtaining information indicative of a resistivity of formation next to a casing.As the use of a device of lateral resistivity profile matrix.For example,Measurements as a tool of well received in a bore of well near a casing may indicate a resistivity of a geological formation through which the hole of shaft esTends.Any errors or interference in the measurements as caused by proximity of the well tool casing can be removed to eliminate the effect of casing on theS gross measurements.In some examples,The libraries of signal and training to include parameters of tube specific coating may be used in conjunction with libraries of training and signal optimized without tube coatingImplement the mapping of measurements as.The corrections and their application to measurements as may be based on the position of a tool of forming of shaft in relation to a point terminal of the casing.
