摘要
元素录井是在钻井现场快速分析岩屑(岩心)样品中元素含量,并根据元素含量及其组合关系的变化进行随钻岩性识别和地层评价的录井技术。在冀东油田上古生界沉积特征分析基础上,通过X射线荧光分析试验,选定对岩石分析的元素种类,研究岩石元素组合特征,并利用其成果及时、准确地识别岩性和判断地层,正确指导钻井生产,形成基于X射线荧光分析的随钻地质解释评价技术。X射线荧光录井的开展,为PDC钻头、空气钻井条件下的岩性识别提供了可靠的技术手段,同时定量的元素分析资料,在复杂岩性的识别、储层评价、地层判别及沉积相的研究等方面,均收到了较好的效果。
Elements logging is a kind of logging technology for realizing the rapid analysis of debris （core） samples＇ element contents in drilling field and making lithologic identification and formation evaluation while drilling based on the element contents and the changes of their combination relationship.Based on the feature analysis of Upper Palaeozoic deposition in Jidong Oil Field,and through X-ray fluorescence analysis test,this paper selects the element types for petrologic analysis,studies the combination characteristics of rock elements,and timely and accurately identifies the lithology and judges the formation by using the results for correctly guiding the drilling production and forming the geological interpretation evaluation technology while drilling based on X-ray fluorescence analysis.The development of X-ray fluorologging technology has provided reliable technical means for lithologic identification under the conditions of PDC bit and air drilling,and at the same time,the quantitative element analysis data have received better results in the identification of complex lithology,the reservoir evaluation,the formation discrimination,and the study of sedimentary facies,etc.
