摘要
该述了煤层气ZQ试1井施工揭露的地层地质概况,钻探施工所需设备,钻孔结构与质量要求,各井段施工钻具组合及钻井参数,绳索取心钻具组合、钻井参数,以及在实践中摸索出来的钻井液的使用技术,取心技术,施工中的关键施工工艺技术与措施等,为今后煤层气勘探井的施工打下了良好的基础。
Summarized the ZQ1 testing CBM well revealed stratigraphic and geologic profiles, drilling equipment needed, well structure and quality requirements, each sector operational and wire line coring drilling tool combinations, drilling parameters. Found out drilling fluid utilization, coring technologies in practice, key operational technologies and measures taken. Those are favorable foundation set for CBM exploratory well drilling henceforth.
