The present application relates to the technical field of
well logging, and discloses a geometry factor adaptive array resistivity curve
correction method, which comprises using resistivity data measured by array resistivity instrument in shallow detection and deep detection
modes as estimated values of invasion zone resistivity and undisturbed formation resistivity, giving an invasion
radius, calculating corresponding geometry factors, and obtaining theoretical resistivity data of different detection
modes through an adaptive correction
processing algorithm. The present application uses the geometry factor adaptive correction
processing algorithm to calculate theoretical resistivity data of different radial detection depths as corrected resistivity data, which conforms to the ordering relationship of resistivity curves of different radial detection depths under the condition of mud invasion, effectively eliminates the resistivity disorder phenomenon caused by array resistivity measurement in complex well conditions, and thus provides more accurate resistivity information of different radial detection depths for
well logging interpreters.
