海拉尔盆地储集层荧光显微图像特征研究与应用

The study and application of fluorescence micro-image characteristics for Hailar Basin reservoir

针对海拉尔盆地地质构造复杂,油、水层解释难度大的特点,在分析石油组分和水荧光显微图像一般特征的基础上,通过对该盆地11口井、154块岩心样品荧光显微图像研究分析,建立了油层、油水同层和水层的定性判别方法,结合含油率、含水率和面孔率可实现储集层的有效评价。现场应用证实,荧光显微图像技术作为录井综合解释评价的一项新技术,随着对其应用研究的不断深入和系统化显微图像特征模板的逐步建立,将成为准确识别储集层油、水分布状态并判断油、水层的一种有效手段。

In accordance with the characteristics that the Geological structures are complicated in Hailar Basin and oil and water zones are difficult to explain,the author established a qualitative discrimination approach for oil zones,oil and water zones and water zones based on the analysis of the general characteristics of the oil component and water fluorescence microscopic images and through the research and analysis for 154 fluorescent microscopic images of core samples from 11 wells in the basin,and the effective evaluation for the reservoir can be achieved together with the oil-bearing rate,the moisture content and surface pore rate.With its applied research being further and systematical and gradual establishment of the microscopic image feature chart,it was proven by the field application that the fluorescence microscopic image technology,which is used as a new way for the interpretation and evaluation of the comprehensive mud logging,will be an effective means to accurately identify the oil and water distribution in the reservoir and identify oil and water layers.
