摘要 高压钢粒子输送是粒子冲击钻井中的关键技术之一。根据传统的螺旋输送装置,设计了一种新型高压钢粒子输送装置,将混合后的2.5mm钢珠与泥浆定量输送至井下。该装置具有如下特点:螺杆轴向力由减速器承担,高压密封装置采用高压机械密封,粒子在高压状态下且固液混合输送。以这种新型螺旋输送装置为研究对象,重点分析了新型螺旋输送装置对粒子输送的运动,以及粒子输送的输送角与螺杆和筒壁摩擦因数的关系,通过分析研究可知螺旋输送机螺杆与粒子的摩擦因数比筒壁与粒子的摩擦因数对输送效率的影响显著,制造加工螺旋输送机时应尽可能减小角螺杆与粒子的摩擦因数,以提高该装置的输送效率。此外,对装置中高压密封结构进行了分析。 Impact drilling is an innovation in drilling technology,which is mainly used in hard rock drilling. Delivery of steel particles under high pressure is one of the key technologies in particle impact drilling. In this paper,the design of a new conveyer device for delivery of steel particles under high pressure is described. The device can quantitatively convey a mixture of 2.5 mm steel balls and mud to the wells. The device has the following characteristics:the axial force of the screw is endured by the reducer,a high-pressure mechanical seal is employed,and the particles in a solid-liquid mixture are conveyed at high pressure. We have analyzed the kinetics of particle transportation,and the relationships between the traction angle of particle transportation and the friction factor between the screw and the cylinder wall. The high-pressure seal structure of the device has also been studied.
