摘要
岩心扫描图像分析是近年来随着信息技术的飞速发展而逐渐兴起的一项岩心观察分析新技术。该文从岩心扫描、图像处理、地质分析3方面对该技术进行了系统介绍,阐述了岩心图像处理和相关沉积构造参数计算方法,并结合实例对岩心图像进行孔缝目标提取及相关参数的自动计算。以车古201井为例,通过岩心观察与岩心扫描图像分析并结合实验室岩矿鉴定和常规物性分析,对该井下古生界奥陶系碳酸盐岩储集层的储集空间发育特征及含油性进行了综合分析研究。
The core scanning image analysis is a new technology of core observation generally rose with the rapid development of information sciences recently. From core scanning, image treatment and geologic analysis three respects, the technology was introduced systematically, and the methods of core image treatment and related sedimentary structural parameter calculation were expounded. Combined with examples, pore and fracture targets were picked up and related parameters were calculated automatically by core images. In the case of well Chegu-201, by core observation and core scanning image analysis and combined with laboratory rock and mineral identification and conventional petrophysical property testing, the pore development and oil-bearing characteristics of the Ordovician carbonate rock reservoirs in the Lower Paleozoic of the well were studied comprehensively.
