岩屑成像技术在远程地质协助中的应用及效果

The Application of Cuttings Imaging Technology in Remote Geological Assistance

摘要: 岩屑成像技术在录井现场应用于岩屑实物的数字化、图像化信息及时有效地传回基地，实现基地专家进行远程地质协助。由现场岩屑图像采集入库、数据实时远程传输、基地图像自动接收、图像资料浏览监测4个分系统组成。主要解决岩屑实物资料图像的高清采集，岩屑白光、荧光、点滴试验3种图像和定量荧光、地化2种图谱资料的实时传输，为基地专家分析决策提供详实图文并茂资料，提高岩屑录井资料的分析和应用水平，达到远程地质协助目的；利用岩屑实物图像资料进行地层对比，进一步确保钻探井位目的层、取心层位的准确卡取；岩屑实物和相关地质资料信息的电子化永久性保存，为实现油田数字化勘探、开发提供更广泛的应用范围。

Abstract: The cuttings imaging technology was used in the logging site to transmit digital and image infor-mation of real cuttings to the base timely and effectively to achieve remote geological assistance by experts in base. It was composed of four sub-systems, namely the collection of on-site cuttings and images and then entry to the database, real-time remote transmission of data, automatic reception of images in base, and scanning and monitoring of image data. It can collect and send the high definition images of cuttings, quantitative fluorescence and geochemical data of two kinds of mapping data, and three images of cuttings, white light, fluorescence, and drop test in real time. With the detailed graphic and text information for analysis, the level of analysis and application of cutting logging data can be improved with the help of experts on the base, and the goal of remote geological assistance is realized. The cuttings physical image data are used for stratigraphic correlation to locate the target layer and core interval accurately. Digital cuttings and related geological information in digital form can be kept permanently, and used in a wider range of applications in digital exploration and development of oilfields.
