岩屑录井数字化技术在塔里木油田的应用

Application of digital technology of cutting logging in Tarim Oilfield

随着钻井工艺及信息化技术的进步,传统的岩屑录井与现代勘探技术的发展已不相适应,岩屑描述数字化技术不断发展,这些技术以岩屑为分析对象,获取岩屑中元素、矿物的含量和放射性数据,从而实现了岩屑数字化分析,突破了传统的岩屑描述录井方法,使录井由定性向定量的发展得以实现。以X射线荧光岩屑录井技术、X射线衍射技术、岩屑伽马技术为代表的岩屑录井数字化技术在塔里木油田应用取得了较好效果,对于该地区地质卡层、特殊岩性识别、储集层的预测起到了重要的作用。

With the progress of drilling technology and information technology,traditional cutting logging can not adapt to modern exploration technology. The digitization technology of cuttings description continues to develop. These techniques take cuttings as an object of analysis,and obtain the content and radioactivity data of the elements and minerals in cuttings. Digital analysis of cuttings has been realized,the traditional cuttings description method of mud logging has been broken through,it makes the development of mud logging from qualitative to quantitative. The digital technology of cutting logging,represented by X-ray fluorescence cutting logging technology,X-ray diffraction technology and cuttings gamma technology,has achieved good results in Tarim Oilfield. It has played an important role in geological horizon determination,special lithology identification and reservoir prediction in this area.
