大庆油田老测井数据治理与高分辨率重构关键技术及其应用
Key technique for old logging series data governance and high-resolution reconstruction for Daqing Oilfield and its application
摘要
Abstract
To address the issues of initial development stage of Daqing Oilfield,including redundant basic data,low-resolution logging curves,incomplete logging projects and partial non-digital data from lateral and JD-581 log-ging series,this study proposes innovative technical system focused on"data governance-curve reconstruction-elec-trode system conversion-parameter modeling".Data governance module is constructed to achieve systematic clean-ing of logging curves and redundant data in database,facilitating standardized data transformation.Innovative"se-quence-constrained+high-frequency information extraction"technique is developed to reconstruct logging curves,reducing relative error of acoustic time difference reconstruction curves to 2.9%.Conversion model of gradient elec-trode system-potential electrode system is established,optimizing conversion algorithm through energy spectrum characteristics.Furthermore,based on petrophysical facies classification,reservoir parameters model is refined,and property parameters laws are further revised using governance data.Field application demonstrates significant improvement in logging interpretation quality,with thin layer identification capability enhanced and 28.8 percent-age points increased in permeability parameter interpretation accuracy compared to conventional methods.This method systematically resolves inefficient utilization of old logging data,and effectively enhances curves data reli-ability.The research provides promotable solution for high-resolution reservoir characterization and targeted poten-tial remaining oil production in Daqing and similar mature oilfields.关键词
