摘要:

胜坨油田胜二区沙二12小层油藏经历了近42年的高效注水开发,造成对反映和记录地下储层真实性变化特征的测井曲线发生相应的变化。根据对子井原理,采用了新、老井叠合对比法和岩心刻度测井方法。通过研究认为,沙二12小层油藏经历较长时间的开采后,电阻率测井曲线变化有随注入水的注入呈持续下降和先降后升两种类型,声波时差测井曲线呈现一直增大的趋势,自然电位曲线随着油藏不同开发阶段出现基线漂移、幅度差变小,微电极测井曲线幅度和幅度差相对变小。

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.

Key words: superimposing correlation, acoustic time logging, electric logging, formation water, oilfield development, Shengtuo oilfield
