为提高沙特HWY区块三开直井段钻进坚硬、强研磨性地层时的机械钻速，在HWY-116井三开井段进行了液动射流冲击器旋冲钻井技术试验。根据液动射流冲击器性能参数与岩石抗钻特性参数的关系，与HWY-116井钻井设计结合，优化了钻具组合，选择了与液动射流冲击器配合的PDC钻头，优化了旋冲钻井参数，形成了适用于HWY-116井的ϕ228.6 mm液动射流冲击器旋冲钻井提速技术。应用该提速技术后，HWY-116井三开井段机械钻速为9.40 m/h，与邻井相同井段相比提高了45.5 %。这表明，应用液动射流冲击器旋冲钻井技术可以提高沙特HWY区块坚硬、强研磨性地层的机械钻速。

In order to raise the ROP in hard and highly abrasive formation in the third spud vertical section of the HWY Block in Saudi Arabia, the rotary percussion drilling technology test with hydraulic jet impactor was carried out in the third spud section of Well HWY-116. According to the relationship between the performance parameters of hydraulic jet impactor and the drilling resistance parameters of rock, the BHA was optimized with the drilling design of Well HWY-116 combined. The PDC bit matched the hydraulic jet impactor was selected to optimize the rotary percussion drilling parameters. Based on these optimizations, a drilling rate improvement scheme was formed for rotary percussion drilling with a ϕ228.6 mm hydraulic jet impactor suitable for Well HWY-116. The ROP in the third spud section of Well HWY-116 was 9.40 m/h, which was 45.5% higher than that of the adjoining wells. The results demonstrated that the ROP in hard and highly abrasive formation in the HWY Block of Saudi Arabia could be improved by the rotary percussion drilling technology with hydraulic jet impactor.
