南方地区页岩气基础地质调查黔绥地1井钻井工艺及完井地质

Drilling Technology of Qiansuidi Well1 for Basic Geological Survey of Shale Gas in the Southern Area of Guizhou Province and Completion Geologic

摘要:

通过黔绥地1井钻井工程实践，从井身结构、取心工艺、护壁堵漏技术措施、井身质量控制等方面分析总结了南方岩溶地区页岩气基础地质调查井施工工艺，并通过黔绥地1井钻井岩心地质编录、随钻气测、有机地化、浸水试验，分析总结黔北绥阳地区地层结构和页岩气含气性特征，为该区的页岩气勘探开发提供地质依据。

Abstract:

By the practice of Qiansuidi well1 drilling engineering, from the well structure, coring process, wall plugging technology, wellbore quality control and other aspects, the construction technologies of shale gas basic geologic survey well in south karst area are analyzed and summarized, and based on the geological record of borehole core of Qiansuidi well1, gas logging while drilling, organic geochemistry and water immersion test, the analysis and summarization are carried out on the stratum structure and gas bearing characteristics of shale gas in Suiyang area of north Guizhou to provide the geological basis for the exploration and development of shale gas in this area.
