为了满足能够快速钻进的需要,各大钻井工程施工队在现场越来越多地使用PDC钻头,从而提高钻井速度,也减少了起下钻次数,同时避免了掉牙轮等复杂的钻井事故,但是在实际应用中常常会有PDC钻头包泥的现象。在经过分析泥包造成原因的基础上,尽量改善钻井液的性能、改变钻井的参数、精心准确的操作等方面,从而提出了针对PDC钻头泥包现象的技术措施,使得更好的解决PDC钻头泥包现象的问题。 In order to meet the needs of rapid drilling, the major drilling engineering team in the field more and more use of PDC bit, thereby increasing the drilling speed, but also reduce the number of drilling times, while avoiding the accidental tooth roller and other complex drilling accidents , But in practice there are often PDC bit mud phenomenon. Based on the analysis of the causes of mud packs, we try our best to improve the performance of drilling fluid, change the drilling parameters, and carefully and accurately operate, so as to put forward the technical measures for PDC bit tundish so as to better solve the problem of PDC bit The problem of muddy phenomenon.
