摘　　要：近年来,南海东部引入烃相态录井,该录井技术主要通过检测钻井液中气态烃类对红外光的吸收变化规律来定性定量的快速评价储层流体性质。该技术采集时间短,检测范围宽,能够在8 s内识别出地层中C1~C5的含量变化,满足在快速钻井条件下,准确识别出油气水层的技术要求,同时该技术采用谱图形式直观表达解释成果,可视化程度高,在南海东部应用效果良好。In recent years,hydrocarbon phase logging has been introduced in the eastern part of the South China Sea.This logging technology is mainly used to evaluate the properties of reservoir flow qualitatively and quantitatively by detecting the absorption ofinfrared light by gaseous hydrocarbons in drilling fluid.With short acquisition time and wide detection range,this technology can identify the change of C1-C5 content in the formation within 8 s,meeting the technical requirements of accurately identifying oil,gas and water layers under the condition of rapid drilling.Meanwhile,this technology uses the form of spectrum to directly express and interpret the results,with high visualization degree,and has good application effect in the eastern South China Sea.
