Dai Shi-hua · Well Logging Technology · 2010
Developed is a conventional log data quality checking software,which can decode different types of raw log data,display log curves rapidly and directly,do log data quality inspection,and then output quality reports.In order to realize automatic checking,the functions of a quality checking system of log data are analyzed.By using Rational Unified Process(RUP),the system models(demand model,object structure model,behavioral model and realizing model) have been built with Unified Modeling Language.Repetitive curve check,depth check and curve consistency check have been conducted by using correlational analysis method.Provided is the process of casing value check and abnormal curve check.This quality checking software can do quality checking for raw log data from following 7 logging systems:CLS3700、ECLIPS5700、CSU、EXCELL-2000、XSKC-92、XSKC-98 and 521.Practical application in Xinjiang oilfield showed that this software can improve quality checking accuracy and working efficiency.
