摘要: 随着油气钻井越来越深,地热钻井越来越多,钻井液面临的高温问题越来越突出,在钻井过程中,对钻井液进行及时冷却并使之达到适宜的温度对于钻井安全是非常必要的。本文总结了目前常用的高温钻井液的冷却方式和特点,综合空气冷却节能的特点和采用载冷剂强制冷却高效的优势,提出了一种高温钻井液高效冷却系统,对冷却系统中空气冷却器、管壳式换热器进行设计、校核、模拟,验证了设计的可靠性,表明使用该冷却方案,能够将80 ℃、1800 L/min的高温钻井液冷却至40 ℃以下,同时还讨论了该冷却系统在不同钻井液温度、不同钻井液流量以及不同气温条件下的冷却效果。Abstract: With the increasing depth of the oil and gas well and the increasing of geothermal drilling, the problem of high temperature drilling fluid is becoming more and more prominent. In the drilling process, it is very necessary to timely cool drilling fluid and make it reach the appropriate temperature for safety drilling. This paper summarizes the cooling ways and characteristics of the current frequently-used high temperature drilling fluid. In regard to the energy-saving characteristics of air cooling and the advantage of high cooling efficiency of the coolant with forced cooling, a high efficient cooling system for high temperature mud is put forward. The air cooler and the tube and shell heat exchanger in the cooling system are designed, checked and simulated, and the reliability of the design is also verified. As a result, the high temperature drilling fluid at 80 ℃ and 1800 L/min can be cooled below 40 ℃ using the cooling system. At the same time, the cooling effect at different drilling fluid temperature, different drilling fluid flow rate and different air temperature conditions is also discussed.
