摘　　要：在煤层气勘探开发井全井段采用岩屑录井,在参数井目的层段采用岩屑录井和岩芯录井,并根据钻时、气测等其它录井资料进行综合分析,准确地判断钻遇地层和岩性,卡准了层位,准确、齐全地录取了各项地质资料。为在煤层气勘探开发减少投资、加快勘探开发速度、增加投资效益、降低安全钻进风险积累宝贵经验。By using the cutting logging in the whole section of exploration well and the cutting and core logging in objective interval of parametric well, the strata and lithology can be judged accurately. Those methods can reduce investment, speed up the exploration and development speed and increase investment benefits.
