Problems solved by technology

In addition, the logging data is the cable depth, and the logging data is the drilling tool depth, so depth misalignment often occurs during data comparison, and it is difficult to give a reliable comparison result (accuracy, conformity rate) or build an accurate model

Abstract

The invention discloses a method and system for butting logging data and logging data, and the method comprises the following steps: determining an error between the logging depth and the logging depth through comparing the logging data with the logging data, and compensating the logging depth, so that the homed logging depth is consistent with the logging depth; performing upward rounding and rounding operation on the logging depth and the homed logging depth; performing averaging operation on the multiple pieces of data corresponding to the same depth after rounding processing; searching thelogging depths in the logging depths and the logging depths in the logging depths, searching the searched depths to select abnormal data, wherein the logging data with the same depth are in butt joint with the logging data. The situation that the result is unreliable due to the fact that the logging data point value is compared with the logging depth segment value at present can be overcome, andthe comparison result with the consistent depth and the segment value compared with the segment value can be reliably established.

Description

technical field [0001] The invention belongs to the technical field of petroleum engineering, in particular relates to mud logging, logging, etc., and in particular to a method and system for connecting mud logging data and logging data. Background technique [0002] Connecting mud logging data with logging data is a basic task for data comparison, coincidence rate statistics, parameter modeling and interpretation modeling, but the data interval of mud logging is usually 1 point / 0.5m, in the non-coring section, the target layer is usually 1 point / 1m, and the non-target layer is usually 1 point / 2m, 1 point / 5m, 1 point / 10m, etc.; while the logging data is Multiple points / 1 meter, such as 8 points / 1 meter, that is, the logging data is the value of a depth segment, while the logging data is the value of a depth point. In addition, the logging data is the cable depth, and the logging data is the drilling tool depth, so depth misalignment often occurs during data comparison, and...
