摘　　要：肯基亚克盐下油田位于西哈萨克斯坦滨里海盆地东缘肯基亚克构造带上,下二叠统、石炭系油藏为裂缝-孔隙型双重介质储层,裂缝发育分布不均。针对肯基亚克盐下构造地层特征,以H8088井钻井效率资料为研究基础,进行了地层强度参数、岩石力学、机械比能建模,反演出基于机械比能和地层岩石力学特性比值的钻进效率评价和参数优选方法,为该区块难钻地层的钻井提速提供技术指导。The Kenkiyak subsalt oil field is located on the Kenkiyak structural belt on the eastern margin of the Binhai Caspian Basin in West Kazakhstan.The Lower Permian and Carboniferous oil reservoirs are fractured porous dual media reservoirs with uneven fracture development and distribution.Based on the drilling efficiency data of wells H8088 and H8089,modeling of formation strength parameters,rock mechanics,and mechanical specific energy was conducted in accordance with the characteristics of the sub salt structural strata in Kenkiyak.The method of drilling efficiency evaluation and parameter optimization based on the ratio of mechanical specific energy to formation rock mechanical properties was reversely performed,providing technical guidance for drilling speed increase in difficult to drill formations in this block.
