    摘要:

    在天阳盆地高温地热钻探施工中,受变质岩系硬岩地层岩性和高温的影响,牙轮钻头机械钻速低、磨损严重、使用寿命短,严重影响钻探施工。对PDC钻头的应用进行了探索研究,针对地层岩性特征,对钻头体、刀翼、剖面轮廓及复合片的选择和布设等关键技术进行了探索,并在钻探实践中优化改进,研究出了一种抗冲击性能较好、适宜于变质岩系硬岩地层的PDC钻头。有效地提高了机械钻速、降低了钻井成本,为天阳盆地高温地热钻探项目的顺利实施提供了技术支撑。

    Abstract:

    In the drilling construction of high-temperature geotherm in the Tianyang Basin, affected by the lithology and high temperature of the hard rock strata of the metamorphic rock system, the cone bit has low mechanical drilling efficiency, serious wear, and short service life, which seriously affects the drilling construction. As a result, the application of PDC bit was explored. Aimed at the lithological characteristics, the key technologies such as the selection and layout of bit body, blade, profile and composite pieces were explored and optimized in drilling practice. A PDC bit with good impact resistance and suitable for metamorphic hard rock formations is developed, which effectively improves the mechanical drilling speed and reduces the drilling cost, which provides technical support for the smooth implementation of the high-temperature geothermal drilling project in the Tianyang Basin.
