摘要
油气资源调查是中国地质调查局"十三五"规划的重要工作内容之一,2016年中国地质调查局实施油气地质调查井54口,2017年部署36口,大多采用机械岩心钻探工艺。本文基于油气地质调查井和机械岩心钻探工艺特点,从地层特点、井控、固井、录井、测井、井下复杂情况等方面对油气地质调查井钻井所面临的技术难点进行了总结和分析,并有针对性地提出了解决方案。本文可为相关管理和作业人员提供技术参考,为油气地质调查井钻井技术攻关和发展提供借鉴。
Oil and gas resources survey is one of the important contents of the 13th Five-Year Plan in China. 54 oil and gas geological survey wells were implemented by China Geological Survey in 2016, and 36 wells deployed in 2017, mechanical core drilling technology is mostly used. Based on the characteristics of oil and gas geological survey wells and mechanical core drilling technology, this paper summarizes and analyzes the technical difficuhies of oil and gas geological survey wells drilling in the aspects of foimation characteristics, well control, cementing, logging and downhole complex conditions, and puts forward targeted solutions. The research results of this paper can provide technical reference for the related managers and operators, and provide experience for the research and development of drilling technology oil and gas geological survey wells.
