Abstract:

The Shaer 12 reservoir in Shenger block,Shengtuo oilfield,has experienced fourty-two years of high-efficient waterflooding development,resulting in a relevant variation of well log that reflects and records the reservoir characteristics.A study based on couplet-well theory is carried out by superimposing correlation techniques of reservoir parameters from new and old wells and by core calibrating logging method.The result indicates that,after a long time of production in the Shaer 12 reservoir,the resistivity logging curves represent two variation patterns with water injection:1) continuously decreasing or 2)decreasing first and increasing afterwards.The acoustic time log has a tendency of sustained increase;the SP curve shows wandering base line and narrow amplitude difference in different development stages,and the micro-electric log displays relatively small amplitude and amplitude differences.
