摘　　要：该文从水平井目的层深度的影响因素入手,对水平井钻时资料失真、岩屑代表性差、钻井液污染、实测岩屑迟到时间不准确及地层构造不落实、小层对比不精细等几方面进行了详细分析,提出了综合应用改进水平井地质录井的方法和手段、加强基础资料综合研究及掌握水平井小层对比的对策,对水平井目的层的准确卡取,获取最大的油层段长具有实际意义。Starting with influence factors in target zone depths of horizontal well, the paper analyzed the conditions of the horizontal well in great detail from the aspects of drilling time data falsification, poor cutting′s representation, drilling fluid contamination, incorrect measured cutting lagging time, non-ascertained stratigraphic structure,unaccurate substrata correlation,etc. and proposed improved geologging methods and means which were comprehensively used in horizontal well and the countermeasures of strengthening the basic information research and performing the correlation between horizontal well′s substrata.The paper has practical significance for sticking target zones of horizontal well accurately and the oil intervals as long as possible can be obtained.
