进一步地，钻头外径小于需要清理管道的通径3mm～5mm。Further, the outer diameter of the drill bit is 3mm-5mm smaller than the diameter of the pipeline to be cleaned.

一种油田管道用清垢清蜡的方法，包括如下步骤：A method for removing scale and wax for oilfield pipelines, comprising the steps of:
1)将钻头置于需要清洁的管道的端部，通电将钻头加热到设定温度；1) Place the drill at the end of the pipe to be cleaned, and heat the drill to the set temperature when powered on;
2)打开超声波发生装置，超声波发射装置发射超声波，旋转电机旋转带动缠绕盘旋转，刚性盘管推动钻头沿管线内部前进，钻头融化蜡质，超声波将融化的蜡质乳化，使其短时间不再凝固堵塞管道；2) Turn on the ultrasonic generating device, the ultrasonic emitting device emits ultrasonic waves, the rotating motor rotates to drive the winding disk to rotate, the rigid coil pushes the drill bit to advance along the inside of the pipeline, the drill bit melts the wax, and the ultrasonic wave emulsifies the melted wax, making it no longer Solidification clogged pipes;
3)在清垢过程中，由压力传感器检测钻头处的压力，当感应压力大于设定值时，电机带动钻头旋转工作，清除管线内垢物，随着垢物被逐渐清除，压力传感器感应压力降低，当感应压力降低到设定压力值以下，钻头停止工作，同时超声波发射装置会把钻头清除的垢物进一步粉碎以防止其堵塞管道；由于钻头外径小于管线通经，钻头和管线之间未清除部分垢物在超声波作用下被进一步清除粉碎；3) During the scale cleaning process, the pressure sensor detects the pressure at the drill bit. When the sensed pressure is greater than the set value, the motor drives the drill bit to rotate and work to remove the scale in the pipeline. As the scale is gradually removed, the pressure sensor senses the pressure When the induction pressure drops below the set pressure value, the drill bit stops working, and the ultrasonic emitting device will further crush the dirt removed by the drill bit to prevent it from blocking the pipeline; since the outer diameter of the drill bit is smaller than the pipeline, the gap between the drill bit and the pipeline The unremoved part of the dirt is further removed and pulverized under the action of ultrasonic waves;
4)当缠绕盘上的刚性盘管使用完而管道仍未清洁完毕，则通过接头来连接另一根刚性盘管；4) When the rigid coil on the winding coil is used up and the pipe is not cleaned, connect another rigid coil through the joint;
5)在清垢过程中，清垢装置发生故障无法继续工作，设置旋转电机反向旋转，通过带动缠绕盘，进而盘绕刚性盘管，带出清垢装置以进行维修。5) During the descaling process, if the descaling device fails and cannot continue to work, set the rotating motor to rotate in reverse, drive the winding disc, and then coil the rigid coil to take out the descaling device for maintenance.
进一步地，所述的钻头加热设定温度高于蜡质熔点5℃～10℃，但低于管道芯管基体的熔融温度，由于超声波装置和加热装置的同时运行清洁，因此对钻头加热设定温度相对于纯钻头加热设定温度有所降低。Further, the set heating temperature of the drill bit is 5°C to 10°C higher than the melting point of the wax, but lower than the melting temperature of the pipeline core tube matrix. Since the ultrasonic device and the heating device are running clean at the same time, the heating setting of the drill bit The temperature is reduced relative to the pure drill heating set temperature.
进一步地，电机可通过压力传感器进行控制，当压力传感器感应到的轴向压力大于60N时电机开始工作，带动钻头旋转从而粉碎管道内的污垢，在轴向压力较小的时候，钻头可以直接通过。Furthermore, the motor can be controlled by a pressure sensor. When the axial pressure sensed by the pressure sensor is greater than 60N, the motor starts to work, driving the drill bit to rotate to crush the dirt in the pipeline. When the axial pressure is small, the drill bit can pass through directly. .
管道清理完毕后，可在管道末端设置缠绕盘和支撑架以收集刚性盘管。After the pipe is cleaned, winding coils and support frames can be set at the end of the pipe to collect the rigid coil.
钻头外径、电机保护套外径、超声波发射装置外径小于管道内径，可避免钻头伤害管道内壁。The outer diameter of the drill bit, the outer diameter of the motor protection sleeve, and the outer diameter of the ultrasonic emitting device are smaller than the inner diameter of the pipe, which can prevent the drill from damaging the inner wall of the pipe.
缠绕盘可一次盘绕刚性盘管的长度为2000m～3000m，可通过续接的方式新接刚性盘管。The winding coil can coil the rigid coil at a length of 2000m ~ 3000m, and the rigid coil can be newly connected by continuous connection.
本发明的有益效果在于：The beneficial effects of the present invention are:
本发明通过加热钻头和超声波同时进行清垢和清蜡，在钻头初步清垢的基础上，超声波进一步清垢，不损伤管道的同时，达到较好的清洁效果，同时适用于弯管清洁操作，适用性广。The invention simultaneously removes scale and wax by heating the drill bit and ultrasonic waves. On the basis of the preliminary scale removal of the drill bit, the ultrasonic wave further removes scale, without damaging the pipeline, and achieves a better cleaning effect. It is also suitable for elbow cleaning operations. Wide applicability.
