摘要
针对无岩芯钻井地层时代划分的困难,文章通过对北京石炭系和二叠系层型剖面标志特征的分析,识别了岩石地层单位的分层标志特征,论述了钻井岩屑地质编录的要求和地层钻探特征,建立了太原组、山西组和石盒子组地球物理测井的物性标志特征,阐明通过岩屑地质编录结合物探测井资料能够较好地对钻井进行地层时代划分。
In view of difficulties of strata division in the no rock -core drilling wells, delamination features of rock stratum units are identified based on section index characters of Carboniferous and Permian strata in Beijing. Requirements of geological loggings of drilling well and strata drilling characters are discussed, and Geophysical characteristics of Taiyuan, Shanxi and Shihezi formations are established. It is proposed that geological documentation combined with geophysical logging data can well divide strata time during drilling.
