摘要
在沿用顾心怡院士原发明专利的基础上,研发并优化设计了XJ675YZ液压蓄能修井机。该修井机采用电机驱动液压泵提供作业动力,并通过特殊的液压控制系统将作业过程中非提升时间的动能和管柱下放时的势能转化为液能储存起来,在提升管柱时再利用储存的能量。优化设计内容包括:主油缸提升能力优化设计;刹车阀缓冲优化设计;滑阀换向缓冲优化设计;底盘载荷布置优化设计及无绷绳抗风载稳定性的优化设计等。该型修井机装机功率小,可以直接使用井场变压器,接电相对安全便捷。和传统机械修井机相比,节能30%,作业噪声降至65 dB,更符合低碳经济需要。
On the basis of using Academician Gu Xinyi＇ s original patent, the development and design optimization of the XJ675YZ hydraulic energy-storing workover rig were conducted. The rig adopts motor to drive hydraulic pump to provide operating power. It converts to the fluid energy for storage the kinetic energy in non-lifting time and the potential energy in string lowering through the special hydraulic control system. The stored energy will be used in lifting string. The design optimization covers the lifting capacity of main oil cylinder, brake valve buffering, slide valve reverse buffering, chassis load arrangement and guyline-free wind load-resistance stability. The workover rig has a small installed power. It can directly use the well site transformer. The electric terminal is relatively safe and convenient. Compared with the traditional mechanical workover rig, it saves energy by 30%. Its operating noise decreases to 65 dB. Therefore, it is much more in agreement with the requirement of low carbon economy.
