摘要
旋转导向钻井技术是目前最先进的钻井技术,为了提高导向钻井工具中驱动器的散热能力,设计了一种新型的电子仓散热结构并用Soildworks实现。该结构采用贴合圆形电子仓的散热基板和肋片状外壁面结合的方式,仅依靠钻井液的循环作为冷却液进行自发散热,相比于内置热管或风扇进行强迫散热的方式,该结构更加经济可靠。导入ANSYS中进行流固热耦合的仿真分析的方式确定此散热结构下驱动器的安全工作范围,即环空处钻井液的最高温度,适用流速以及黏度。所设计的散热机构为解决导向钻具内发热元件的散热问题提供了一条新的途径。
Rotary steering drilling technology is the most advanced drilling technology at present.In order to improve the heat dissipation capacity of the driver in the steering drilling tool,a new type of electronic warehouse heat dissipation structure was designed,and implemented with Solidworks.The structure adopted the method of combining the heat dissipation substrate of the circular electronic warehouse and the fin-shaped outer wall surface,and only relied on the circulation of the drilling fluid as the cooling fluid for spontaneous heat dissipation.Compared with the built-in heat pipe or fan for forced heat dissipation,the structure was more economical and reliable.The safe working range of the driver under the heat dissipation structure was determined by the simulation analysis of fluid-solid-heat coupling,the maximum temperature of the drilling fluid in the annulus,the applicable flow rate and viscosity.The heat dissipation mechanism designed provided a new way to solve the heat dissipation problem of the heating element in the steering drill.
