摘要 套管开窗侧钻小井眼水平井钻井技术的特殊性及复杂性给传统常规录井带来了严峻的挑战。该文从苏北油田几口老井套管开窗侧钻小井眼水平井的常规录井角度出发,探讨了岩屑录井过程中的迟到时间选择以及岩屑的捞取与岩性识别,分析了对常规荧光录井的影响,指出了常规录井遇到的难点及应对措施。为今后此类井的常规录井积累了一定的经验,具有一定的指导作用。 The particularity and complexity of sidetracking horizontal wells through the opened casing hole has brought severe challenges to conventional mud logging. As for the conventional logging in sidetracking slim hole horizontal wells which were opened through casings in the several old wells of North Jiangsu Oilfield, the paper discussed lag time selection, cutting bailing and lithology identification during cutting logging, analyzed the influence on conventional fluorescence logging, and pointed out difficult points encountered by conventional mud logging and dealing measures. It accumulated a certain experience and it was of a certain guiding function for conventional logging in sidetracking horizontal wells.
