岩石薄片全视域多维数字化图像采集技术研发及应用

Development and application of full⁃view multi⁃dimensional digital image acquisition technology for rock slices

针对目前老井库存岩石薄片老化、丢失,无法实现数字化图像共享以及新井现场岩石薄片应用浅表化等问题,研发了岩石薄片全视域多维数字化图像采集技术,实现了对岩石薄片的广域、多维度地质特征识别及同屏多人协同研讨,增强了对岩石薄片内特殊矿物、孔隙、裂缝等特征认识的统一性、准确性。全视域多维数字化岩石薄片图像所反映的地质特征较传统岩石薄片更加丰富,岩性特征识别更加准确,更有利于支撑地质沉积与成岩演化研究。该技术的研发与应用,不仅实现了早期老井库存岩石薄片的数字化存储,同时有利于现场勘探中储层的快速评价,从而为油田勘探开发的数字化建设提供了有力支撑。

In view of the aging and loss of rock slices in old wells,digital image sharing can not be realized,and the application of rock slices in new wells was superficial,the full-view multi-dimensional digital image acquisition technology of rock slices was developed,which realized the wide-area and multi-dimensional geological feature recognition of rock slices and the collaborative discussion of many people on the same screen,and enhanced the unity and accuracy of understanding the special minerals,pores,cracks and other characteristics in rock slices.The full-view multi-dimensional digital rock slice image reflects more abundant geological features than traditional rock slices,and the identification of lithologic features is more accurate,which is more conducive to supporting the study of geological sedimentation and diagenetic evolution.The research and application of this technology not only realizes the digital storage of rock slices in early old wells,but also facilitates the rapid evaluation of reservoirs in field exploration,which provides favorable support for the digital construction of oilfield exploration and development.
