Abstract

The sampling spacing of different series of old well data curves is varied and does not facilitate multi-well batch interpretation. This study achieves automatic interception of invalid well sections and reads valid sections into memory, increasing the speed of computing and the number of wells processed in batch; it also achieves automatic error detection and curve normalization, and outputs data files with useful curves and interpretation results, increasing the speed of computer operation and the number of wells processed in batch for old wells.
