测井资料中蕴藏着反映地层变化规律、岩石抗压强度和岩石可钻性等信息,由此建立了声波时差和地层抗压强度优选钻头类型的方法,使之与所钻地层更加合理的匹配。实践证明,利用测井资料进行钻头选型是科学、实用和简捷的钻头选型方法。
The logging data contains information that reflects the formation variation, compressive strength of rock and rock drillability. Based on this, the method of optimizing the type of bit with sonic time difference and formation compressive strength is established to make it more reasonable match with the drilled formation . Practice has proved that the use of logging data for bit selection is a scientific, practical and simple bit selection method.
