摘　　要：针对板式换热器对油基钻井液冷却效果差的问题,通过数值模拟的方法开展了换热器波纹板在不同波纹倾角(35°~75°)、不同波纹节距(8~16 mm)和不同波纹高度(3~7 mm)结构下对油基钻井液冷却性能的影响分析。通过物理试验验证了数值模拟方法的可靠性,并基于响应面试验设计方法,建立了冷却效果与处理量为综合评价指数的响应面模型,分析了参数间的交互作用和3个因素的敏感性,其敏感性顺序从大到小为:波纹倾角、波纹高度、波纹节距。其中优化后模型对油基钻井液进出口温差相比原现场应用结构模型提升了31.1%,可提高冷却性能。同时通过数值模拟对预测值进行了验证,综合评价指数E误差为4.95%,所得结果为板式换热器对油基钻井液冷却性能的现场应用提供了一定的参考依据。In order to solve the problem of poor cooling effect of plate heat exchanger on oil-based drilling fluid,the influence of corrugated plate of heat exchanger on the cooling performance of oil-based drilling fluid under different ripple inclination angles(35°-75°),different ripple pitches(8 mm-16 mm)and different ripple heights(3 mm-7 mm)was analyzed by numerical simulation.The reliability of the numerical simulation method is verified by physical experiments,using the response surface method,a response surface model with cooling effect and processing capacity as the comprehensive evaluation index is established,and the interaction between the parameters and the sensitivity of the three factors are analyzed,and the sensitivity order from large to small is as follows:ripple inclination,ripple height,and ripple pitch.Among them,the temperature difference between the inlet and outlet of oil-based drilling fluid in the optimized model is increased by 31.1%compared with the original field application structural model,which can improve the cooling performance.At the same time,the predicted value is verified by numerical simulation,and the error of the comprehensive evaluation index E is 4.95%,which provides a certain reference for the field application of plate heat exchanger on the cooling performance of oil-based drilling fluid.
