摘　　要：随着勘探开发的不断深入,深层煤岩气已逐渐成为勘探的主要对象之一。黄骅坳陷乌马营聚煤带深层煤岩气未来可能成为大港油田实现产能接续的重要领域,然而该区域的煤岩气勘探录井技术尚无经验可循,随钻录井评价尚属盲区,为此,通过分析黄骅坳陷乌马营聚煤带7口井山西组和太原组煤系地层的多项录井技术数据,总结技术特征,初步形成了煤岩品质、含气品质、烃源岩特性、荧光特性随钻录井评价方法。该方法在研究区石炭-二叠系煤系地层综合评价应用中表征较好,为黄骅坳陷深层煤岩气下步勘探部署提供了有力地质依据。As exploration and development progress,deep coal-rock gas has gradually become one of the main targets for exploration.The deep coal-rock gas in the Wumaying coal accumulation belt of the Huanghua Depression may become an important region for sustaining production capacity in the Dagang Oilfield in the future.However,there is no existing experience in mud logging technology for coal-rock exploration in this region,the evaluation of mud logging while drilling is still blind area.Therefore,by analyzing the data of the multiple mud logging techniques of the Shanxi Formation and Taiyuan Formation coal measure strata from 7 wells in the Wumaying coal accumulation belt of Huanghua Depression,and summarizing the technical characteristics,the method of evaluation while drilling for coal-rock quality,gas bearing quality,characteristics of source rocks and fluorescence was initially formed.The method is well characterized in the comprehensive evaluation of Carboniferous-Permian coal measure strata in the study region,which provides favorable geological basis for the next exploration and deployment of deep coal-rock gas in Huanghua Depression.
