| 摘 要： | 岩石可钻性是钻头选型、提高钻井效率的基础，利用测井资料预测岩石可钻性是行之有效的手段。通过室内试验，重点研究岩性、密度和泥质含量对岩石可钻性的影响规律。在已有的可钻性与声波时差关系模型基础上，考虑不同岩石岩性、密度和泥质含量对其可钻性级值的影响，建立了新的岩石可钻性综合预测模型。经验证，该模型预测精度较高，能满足工程需要。

| Abstract: | Rock drillability is significant for selecting proper bit and improving drilling efficiency, and can be properly predicted by well logging information. Through lab tests and theoretical researches into effects of lithology, density, and silt content on rock drillability a novel comprehensive prediction model is established based on available relations between drillability and interval transmit time and factors such as varied lithology, density, and silt-content. The accuracy of the model is validated and can meet the requirements of engineering applications. |
