| 中文摘要:岩石可钻性是决定钻井效率的基本因素，反映了钻进时岩石破碎的难易程度，是合理选择钻进方式、钻头类型和设计钻进参数的依据。基于地层岩石可钻性的计算方法，结合实钻井的测井资料分析，建立了准噶尔盆地中部区块地层岩石可钻性剖面，并以此为依据推荐了适用于不同地层的钻头类型，现场应用结果表明，所用钻头具有很好的适用性，能够进一步提高准噶尔盆地中部地区的机械钻速，对于该地区的后续钻井钻头类型的选择具有重要的指导意义。 |

| Abstract:Rock drillability is the key for drilling efficiency， which reflects the fragmentation， and is the base for drilling model， type of drilling bit and drilling parameters designing. According to the calculation method of rock drillability and the logging data， the profiling of rock drillability is built， based on which, different types of drilling bit are suggested. The application results show that these drilling bits can increase penetration rate in the central part of Junggar Basin with guiding significance to bit selection for subsequent drilling. |
