塔东区块庆玉1井超深井优快钻井技术

Premium Drilling Technology for Ultra-deep Well Qingyu 1 in Tadong Block

随着油气勘探开发逐步从深层向超深层领域推进,塔东区块储层埋藏深,井下温度高、地质条件异常复杂,使得钻速慢、钻井周期长和钻井风险高。庆玉1井是大庆钻探工程公司在该区块钻的最深的井,为打好打成该井,开展施工难度因素分析,制定技术措施,应用高温仪器、工具、钻井液,施工参数优化等方法,研发超深井配套工艺技术,并结合现场施工要求,实现了塔东区块超深井庆玉1井的优快安全钻井。结果表明:该技术具有安全高效的优点,为深层、超深层油气的经济有效开发提供有效工程技术手段。

As oil and gas exploration and development gradually advance from deep to ultra-deep fields,the Daqing Tadong flow block presents unique challenges due to its deep reservoir burial,high downhole temperature,and unusually complex geological conditions.These factors result in slower drilling speeds,longer drilling cycles,and elevated drilling risks.The Qingyu 1 well represents the deepest well ever drilled by Daqing Drilling in this block.In order to successfully drill this well,a comprehensive analysis of the construction difficulty factors was conducted,followed by the formulation of technical measures,the application of high-temperature instruments,tools,drilling fluids,and the optimization of construction parameters.This paper presents a methodology for the safe and efficient drilling of super-deep wells,exemplified by the successful completion of the Qingyu 1 well in the Tadong block.The approach involves the development of specialized technology for super-deep wells and its integration with on-site construction requirements.The results demonstrate the efficacy of this technology in ensuring safety and high efficiency,while providing effective engineering solutions for the economic and efficient development of deep and ultra-deep oil and gas resources.
