摘要
论文以A油田W区块为研究对象,A油田W区块储层具有物性差、非均质性强以及注入水矿化度变化大等特点.在分析渗透率韵律(正韵律、反韵律、复合韵律)及层内夹层(泥质夹层和钙质夹层)的基础上,研究了储层非均质性对地层电阻率的影响.研究发现储层渗透率韵律及夹层控制注入水波及范围,影响该层位地层电阻率变化,最后总结了地层电阻率变化规律.研究成果为提高该地区水淹层解释符合率奠定了良好的基础.
Based on the analysis of permeability rhythm (including :positive rhythm ,reverse rhythm and composite rhythm ) and intraformational bed (including muddy intercalation and cal‐careous intercalation ) ,we researched the impact of the reservoir heterogeneity on formation re‐sistivity .In the end ,we got some conclusions :the permeability rhythm and the intraformational bed influencing formation resistivity with gravity by controlling injected water ripple range .This conclusion can lay the foundation for improving valuative veracity about water-out reservior inter‐pretation ..
