【摘要】：塔里木盆地轮南2油田JIV油组电阻率普遍偏低,个别油层电阻率比水层电阻率还低,含油性评价主要根据试油和试采结论;未试油层段储层含油和油藏油水界面不明确。为精细解释储层流体性质、判断油水界面及解决采收率低等问题,利用轮南2油田JIV油组12口取心井的岩石热解和荧光薄片图像分析进行流体性质划分,明确在不同流体性质下岩石热解数据和荧光显微图像的变化特征。利用岩心含油性观察、岩心物性分析和生产动态资料,制定划分储层流体性质的方法,建立一套适合轮南2油田JIV油组的流体性质半定量划分标准。生产动态资料分析证明流体性质划分标准的准确性和方法的实用性。
[Abstract]:The resistivity of JIV oil group in Lunnan 2 oilfield of Tarim Basin is generally low, and the resistivity of some reservoirs is lower than that of water layer. The oil-bearing evaluation is mainly based on oil testing and production test, and the oil-bearing and oil-water interface of reservoir in untested reservoir is not clear. In order to accurately interpret the reservoir fluid properties, judge the oil-water interface and solve the problems of low oil recovery, the rock pyrolysis and fluorescence slice image analysis of 12 core wells in JIV oil formation of Lunan 2 oilfield are used to classify the fluid properties. The variation characteristics of rock pyrolysis data and fluorescence microscopic images under different fluid properties are clarified. Based on the observation of core oil content, core physical property analysis and production dynamic data, a method for classifying reservoir fluid properties is established, and a set of semi-quantitative classification criteria for fluid properties of JIV oil group in Lunan 2 oilfield is established. The analysis of production dynamic data proves the accuracy of the classification standard of fluid properties and the practicability of the method.
