坚硬地层用低温电铸孕镶脉冲石油钻头的研制及其水力性能数值模拟

Research on Development of Low-temperature Electroplated Impregnating Pulse Petroleum Bit and Numerical Simulation of the Hydraulic Performance

针对PDC钻头和牙轮钻头在坚硬、研磨地层中钻速较低、寿命短的问题,研制了一种低温电铸孕镶脉冲石油钻头,并对钻头的流场进行了数值模拟。现场应用表明,该钻头具有寿命长、机械钻速高的特点。

According to the low drilling speed and short service life of PDC bit and cone bit in hard and abrasive formation,a low temperature electroplated impregnating pulse petroleum bit was developed,and numerical simulation of flow field of the bit was made.The field application shows that the bit has long service life and high penetration rate.
