摘要
近几年来,多种录井仪器在大庆深部地层录井过程中,钻遇烃类气层时,经常出现只有C1和C3,而没有C2的现象。从地层、钻井液和仪器三方面查找原因,查出是色谱柱对C1与C2分离性能低的问题。建议把无C2检验作为一项新的色谱柱性能检验指标,实行无C2检验可以提高色谱柱出厂的质量和气测录井资料的质量。
In recent years,various kinds of logging units often run into the occurrence of C\-1 and C\-3 without C\-2 by detection when they are operated in Daqing deep formation which bears hydrocarbon gases.By analysing formation,drilling fluid and instrument,it was found that this problem was caused by chromatograph column which can not efficiently seperate C\-1 and C\-2.The author suggests making the datection without C\-2 as a new kind of verification specification for chromatograph column,it can improve the quality of chromatograph column manufacturing and gaslogging data.
