摘　　要：为提高长水平段水平井钻压传递效率,模仿蚯蚓的生理结构和运动原理,研制了一种仿生蠕动钻进工具。该工具利用一个脉冲发生器驱动多个振动短节,能够在实现钻柱蠕动的同时降低水力压耗。室内测试结果表明:排量为30L/s时,仿生蠕动钻进工具的压力波动幅值接近2 MPa、振动频率为6.5 Hz,3个振动短节的振动幅度超过5 mm。该工具在新疆油田JHW8X-3X井水平段进行了现场试验,进尺815.00m,平均机械钻速12.48m/h,与邻井水平段采用振荡螺杆和水力振荡器等减阻提速工具相比,平均机械钻速提高了15.5%。研究表明,仿生蠕动钻进工具能够缓解钻柱托压、提高钻压传递效率,为提高长水平段水平井的钻进效率提供了新的技术手段。By mimicking the physiological structure and movement principles of earthworms,a bionic peristaltic drilling tool was developed to enhance the transfer efficiency of weight on bit(WOB)in long horizontal sections of horizontal wells.The tool used a pulse generator to drive multiple vibration subs,which enabled the drill string to perform peristaltic motion while reducing hydraulic pressure loss.Laboratory tests show that at a flow rate of 30 L/s,the tool’s pressure fluctuation amplitude reaches nearly 2 MPa,with a vibration frequency of 6.5 Hz,and the displacement amplitude of the three vibration subs exceeds 5 mm.The field test is conducted in the horizontal section of Well JHW83-31 in Xinjiang Oilfield,with drilling footage of 815 m and an average rate of penetration(ROP)of 12.48 m/h achieved.Compared with adjacent wells adopting drag reduction and speed increase tools such as oscillating screws and hydraulic oscillators,the average ROP increases by 15.5%.The field test results indicate that the bionic peristaltic drilling tool can alleviate the problem of drill string friction,promote the transfer efficiency of WOB,and offer an effective solution for improving the drilling efficiency of long horizontal sections in horizontal wells.
