摘要
针对大庆油田东部地区油层是否产水的实际问题,利用阿特拉斯公司高分辨率阵列感应(HDIL)测井资料与常规测井资料相结合,研究确定了高分辨率阵列感应在大庆东部地区的适用条件,建立了解释图版。高分辨率阵列感应测井在大庆东部地区的应用需具有一定的条件。当孔隙度大于13%或泥质含量小于25%,可以通过高分辨率阵列感应测井资料对不同储层的不同侵入特征有效地识别流体性质;当孔隙度小于13%或泥质含量大于25%,侵入特征不明显,高分辨率阵列感应测井无法识别流体性质。在大庆油田东部地区有阵列感应测井资料的井中选取16口井50个解释层,以侧向电阻率值和阵列感应反演的原状地层真电阻率与侧向电阻率的比值作交会图。实例给出HDIL在大庆油田东部油田的应用情况。
To solve the problem wheather the production zone produces water or not, used is the Atlas High Definition Induction Log （HDIL） data and conventional log data to determine the application conditions of HDIL method in east Daqing oilfield and establish its interpretation chart. When porosity is higher than 13% or shale content is lower than 25% ,the HDIL data may be used to effectively identify fluids properties in different reservoirs with different invasions; When the porosity is lower than 13%, or the shale content is higher than 25%, the invasion features are not clear, so the HDIL data is not able to identify the fluids. The HDIL data from fifty interpretating zones in 16 wells are selected to make a Rt- Rt/RLLd,3 crossplot. Case study shows the HDIL is beneficial to improve the interpretation agreement in this oilfield.
