空气钻井用空压装置结构优化

Structure optimization of air compression equipment for air drilling

国产空压装置在排气量、排气压力方面不能满足空气钻井的需要,急需研制满足空气钻井使用的空压装置。为此,依据空压装置的工作流程,制定了3种结构方案,采用CFD软件对空压装置进行整机数值计算。由数值计算结果知,3种方案中空气在空压装置机组舱内可以形成合理的气流通道,实现机组舱的通风散热。根据3种方案结构上的优缺点,最终确定方案Ⅰ为空压装置模型。研究成果LK-30/2.5QZ空压装置目前在现场使用情况良好,运行正常。

Since the air compression equipment in China can not meet the requirement of the air drilling,development of air compression equipment which can be used in air drilling is urgently demanded.Therefore,three different structure schemes are designed based on the work flow of the air compression equipment,and a CFD software is used for the numerical calculation of the overall machine.The calculation result shows that air can form reasonable airflow channel in the generator set cabin of the air compression equipment,realizing the ventilation and heat dispersion in the generator set cabin.Considering the structure advantages and disadvantages of the three schemes,Scheme I is finally determined as air compression equipment model.The LK-30/2.5QZ air compression equipment developed by the research team is working in good condition on the spot.
