摘要
Abstract
This paper mainly studies the division and evaluation of super heavy oil reservoirs in the Russian Republic of Tatarstan based on the comprehensive method of nuclear magnetic resonance (NMR),and realizes the real-time NMR analysis of full diameter cores in the well site by using the ground-moving nuclear magnetic core analyzer.The reliability of the experimental results was verified by laboratory NMR standard rock samples and asphalt sample analysis,as well as other logging methods.Three kinds of Russian nuclear magnetic resonance logging tools are introduced,and a natural asphalt well is used as an example to show the T2 spectrum characteristics of the asphalt reservoir,the Kazan Formation mudstone and the remaining asphalt reservoir in the Russian Republic of Tatarstan.At the same time,the paper introduces the ability of two-dimensional nuclear magnetic resonance (T1,T2) spectrum to identify the heavy oil by the moving full-diameter core nuclear magnetic resonance measuring instrument,and proposed that the asphalt stratum with different viscosity needs to select suitable T2 cut-off value.Finally,the experimental results of fluid content in 1 m long full diameter core with time are presented,which reflects the process of loss of fluid from the core pore space.Therefore,the mobile full diameter core nuclear magnetic measuring instrument has a good application prospect in the field.关键词
