摘　　要：从沉积岩石学基础理论出发,依据常规测井资料对不同岩性地层的反映能力,将连续的沉积剖面划分为不同的地质单元,并针对各类地质单元分析其测井响应特征,建立了系统的岩性识别方法。采用大庆油田长垣第一至六采油厂的12口取心井773层数据建立了常规测井资料的岩性综合判别标准,判别符合率达到88%以上。在合理的自动分层取值基础上,实现了连续岩性剖面的判别。经过大庆长垣15口井5 008层的岩性判别验证,岩性判别综合符合率达到85.5%。说明这种岩性判别技术具备很好的实用性和推广应用效果。On the principle of sedimentary petrography, continuous sedimentary section is divided into various geologic units based on conventional well log data responded to various lithologic formations, and well logging response characteristics is analyzed, and lithology identification method is established. Lithologic comprehensive identification rule for conventional well log data is set up on the basis of the data of 773 layers came from 12 coring wells in No. 1-6 Oil Production Company of Daqing Placanticline with over 88% coincidence rate of identification. Thus, based on the reasonable automatic layering, it realizes identification of continuous lithology section. In addition, the application of this technique in 5 008 layers in 15 wells of Daqing Placanticline shows that comprehensive coincidence is up to 85.5%. It indicates that this technique has great practical value and application value.
