摘要

葡萄花油田葡47区块葡萄花油层非均质性明显,油水分布复杂.其中,葡472区块原测井解释与新井试油结论符合度较低.结合缺少研究区目的层油基泥浆取心实际情况,充分利用已有资料,以录井、测井、试油、测试等资料为基础,对研究区含油饱和度测井解释模型及油水层判别标准进行研究.利用试油资料回归变参数阿尔奇公式,建立适合研究区目的层的含油饱和度测井解释模型.利用区块附近井及区块内取心井其他层位压汞毛压曲线回归适合研究区的测井解释参数,标定合适的油水界面,确定含油高度,建立"J函数"法含油饱和度模型."J函数"法含油饱和度模型与试油标定法含油饱和度模型拟合结果基本一致.结合试油及生产资料,建立区块油水层电性识别图版,结合成藏特征完成油水性质综合判别,为指导油田开发生产打下基础.
        The heterogeneity of Putaohua reservoir is obvious. The oil-water distribution is complex in the 47 block of Putaohau oil field. In this paper, the saturation logging interpretation model and the oil-water layer criterion of the 472 block are studied based on the data of well logging, logging, test, testing and so on, with the actual situation of the lack of oil base mud coring core. First, the oil saturation logging interpretation model suitable for the target layer of the study area is established by using the variable parameter Archie formula with the regression of the test data. The oil saturation model of " J-Function" method is established by using the pressure mercury capillary curve regression to the logging interpretation parameters suitable for the study area, calibrating the suitable oil-water interface, determining the oil-bearing height. The model of oil saturation of "J-Function" method is consistent with the fitting result of oil saturation model with the test oil calibration method. According to the block test oil and production means, the paper establishes the electrical identification chart of oil-water layer in the block. Finally, reservoir fluid identification was carried out on 459 layers of 45 wells in Putaohua formation in 472 block.
