摘　　要：HT油田地层岩性、油水关系复杂,油水层识别困难。从逐点计算和分层测井解释结果中优选提取了4个参数作为识别油层、油水同层、水层的特征参数,采用改进的两向量判别分析交会图法建立了工区油水层识别的典型图版。实际应用表明,该方法判别的油水层结论与射孔结论吻合情况较好,符合率高达90%。The identification of reservoir fluid property is an important content of fine oil well log interpretation. In HT oilfield, both the formation lithology and relation of oil and water are complex, which makes it difficult to identify the oil and water layers. By withdrawing four parameters, the SP, RLIA Х CNL, RILd and DEN, from the point to-point computation and the lamination well logging interpretation results to identify the oil layers, the oil/water layers, and the water layers, we establish the oil/water layer identification typical chart with improved two vectors cross plot. Practical applications show that the identification result of this method is in good accordance with the perforating result, and the prediction accuracy reaches 90%.
