胜坨油田坨七断块水淹层测井解释技术研究

Study on Waterflooded Zone Logging Interpretation for Fault-Block Tuo 7 of Shengtuo Oilfield

针对胜坨油田坨七断块水淹层在测井曲线上的变化特征,以测井资料和岩心分析资料为基础,建立了沙二段1、2+3砂层组水淹层测井解释模型,划分了水淹级别。对该区135口井进行了测井资料数字处理与解释。试油结果表明,解释符合率在86%以上,说明该方法在本区定量计算水淹层是有效的。

This paper discuss the variation features of well logging curves corresponding to waterflooded zone for Fault-block Tuo 7 of Shengtuo Oilfield.Based on the well logging and core analysis data,the well logging interpretation models for waterflooded zone in 1,2+3 sand groups of Es_2 are established and waterflooded degrees are determined.135 wells in waterflooded zone have been processed and interpreted for this area.Actual results show that the coincidence rate reaches more than 86 percent,which proves that the method is more effective in the well logging interpretation of the waterflooded zone in this area.
