为了进一步提高塔河油田深部硬地层的机械钻速，基于旋冲钻井技术理论与实践经验，开展了液动射流冲击器＋PDC钻头提速技术研究与实践，探索液动射流冲击器与PDC钻头配合使用提高深部地层机械钻速的技术可行性。首先根据塔河油田深部硬地层的特点及与冲击器配合的要求，优选了PDC钻头；接着利用液动冲击器性能测试系统，测试了液动冲击器各结构参数对其性能的影响；最后根据测试结果及所优选PDC钻头的抗冲击性能，确定了液动射流冲击器的结构及性能参数。液动射流冲击器与 PDC钻头配合在S1163井、T P324井和T P328X井的奥陶系地层进行了应用，机械钻速与同井上下井段及邻井相同井段相比，提高了32％～45％。这表明液动射流冲击器与PDC钻头配合使用，可以提高塔河油田深部地层的钻速。
