油气地质调查井钻井技术问题与对策

Problems and Countermeasures of Oil and Gas Geological Survey Drilling

摘要:

油气资源调查是中国十三五规划的重要内容之一，2016年中国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，并有针对性的提出了解决方案。本文研究成果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。

Abstract:

Oil and gas resources survey is one of the important contents of the 13th Five-Year Plan in China. In 2016, China implemented 54 oil and gas geological survey wells, 36 deployed in 2017, most of the wells uses mechanical core drilling technology. Based on the characteristics of oil and gas geological survey wells and mechanical core drilling technology, this paper summarizes and analyzes the technical difficulties faced by gas geological survey wells from the aspects of formation characteristics, well control, cementing, logging and downhole complex problems, and puts forward targeted solutions. The research results of this paper can provide technical reference for the relevant management and operation personnel, and provide reference for the research and development of drilling technology for oil and gas geological survey.
