近年来PDC钻头配合动力钻具在现场应用良好 ,但同时暴露出造斜率控制难以掌握的实际问题。结合现场实际 ,浅析了动力钻具 +PDC钻头钻进时 ,PDC钻头结构特征因素对造斜率的不同影响。多口井的钻井实践证明 ,优选结构合理的PDC钻头可达到有效控制造斜率、提高钻井速度、降低钻井成本之目的 In recent years, PDC bits and dynamic drilling tools have been applied well in the field, but at the same time, actual problems that are difficult to be controlled by the slope control are exposed. According to the actual situation in the field, the different influence of PDC drill bit structure characteristics on the slope-building rate was analyzed when the power drill + PDC bit was drilled. Drilling practice of many wells proves that the PDC cutter with reasonable structure can achieve the purpose of effectively controlling the slope, increasing the drilling speed and lowering the drilling cost
