摘要
水平定向钻在穿越复杂地质情况下,施工中容易出现钻孔坍塌、钻杆断裂等技术难题。通过对超声波在定向钻泥浆中传输规律的研究,建立了定向钻剖面测量的超声工艺模型,在嵌入式控制平台上开发出用于水平定向钻孔剖面测量的超声测量系统,可以对钻孔形状进行测量,对穿越轨迹上的地质情况进行核查,并通过检测软件对穿越轨迹进行三维剖面图显示,指导复杂地质条件下的水平定向钻施工过程,降低穿越风险。
In complex geological conditions,horizontal directional drilling would be hard to be implemented.Many technical problems appear,such as the bore collapsing and the drill pipe fracturing.Through the study of the ultrasound propagation in the mud,Pipeline Research Institute of CNPC has established a ultrasound model for measuring the directional drilling profiles,and further research measurement system on embedded control platform to figure out the bore shape and the trajectory geological conditions.By the detecting software,the cross trajectory can be displayed in 3D.This system is capable of conducting horizontal directional drilling in complex geological conditions to reduce the risk of crossing.
