非常规油气作为重要战略接替能源，其高效开发是缓解我国油气资源短缺、保障国家能源安全的重要举措。介绍了国内外非常规油气的钻井技术，结合胜利油田非常规油气储层特点，分析了钻井技术的难点，借鉴国外经验，研究形成了非常规油气的钻井工程设计技术、优快钻井技术、钻井液技术等3方面的核心技术，并在胜利油田进行了现场试验。应用结果表明，初步形成的配套技术，能够保证非常规油气井的顺利完钻。目前已完成4口井的钻探，均取得了良好的钻探效果，为国内非常规油气藏高效开发提供借鉴。

The efficient development of unconventional oil and gas, an important strategy succeeding resource, is an important measure to alleviate the shortage of oil and gas resources and guarantee national energy security. The international drilling techniques for unconventional oil and gas reservoirs are introduced. Considering the unconventional oil and gas reservoir characteristics in shengli oilfield, the difficulty of drilling technique is analyzed. Learning from the experience overseas, three core techniques are formed, including drilling engineering design, high quality and fast drilling technology and drilling fluid technology, and field tests are conducted in Shengli oilfield. The application results show that the developed matching techniques can ensure drilling success and high quality. The drilling of four wells has completed and achieved good results, which provide a reference for efficient development of unconventional oil and gas reservoirs domestically.
