摘要: 通过实验室高温高压岩电实验、数值模拟及不同泥浆类型测井资料的综合分析,认为盐水泥浆滤液侵人较深是造成辽河油田海南构造带油气层电阻率低的主要原因。针对该地区的特点,研究了一套具有三级精度控制的侧向测井曲线混合反演技术,计算地层的真电阻率Rt和侵人带直径Di;利用岩心分析和测井等资料建立了孔隙度、泥质含量、束缚水饱和度和含水饱和度等基础参数的解释公式和油气水层识别标准,编制出相应的测井评价软件ninv和paracom.该方法已成功地应用于处理该地区11口井测井资料,取得明显的地质效果。

Abstract: Based on the high temperature and high pressure lab measurements,the numerical simulations and the general analysis ofthe well logs of the different kinds of drilling muds,this article considers the very deep invasion of the conductive salty mud to bethe main reason of the low resistive hydrocarbon-bearing formations in Hainan Zone,Liaohe.For the local geological features,athree-accuracy controlled hybrid inversion technique of the Dual Lateral Log is put forward to calculate the true formation resistivity Rt,and the invasion diameter Di.With the core analytical data and the well logs,the mathematical models of porosity,shalevolume content,irreducible water saturation and water saturation as well as the criteria of the hydrocarbon bed or water bed areestablished.The corresponding well logging evaluation software ninv and paracom are developed.The technique is successfullyused to process 11 well logs of this area and good geological results are achieved.

Key words: well logging evaluation, salty mud, formation resistivity, water saturation
