Problems solved by technology

[0002] Due to seasonal reasons in northern oilfields, for some oil wellhead water-mixed pipelines and water wellhead pipelines, blockages often occur in winter due to internal freezing. The liquid in the pipeline stops flowing, causing a large area of ​​the entire pipeline to freeze, causing oil and gas wells or water wells to stop production. The method can only be used when the freezing of the pipeline is not serious. This method is not only inefficient, but also has potential safety hazards during the operation, and it is easy to burn the operator
[0003] In winter in the northern region, pipelines are often frozen and blocked during construction operations, but open flames are strictly prohibited on the oil well site. The common practice on site is to use steam trucks to unblock pipelines with high-temperature steam, but this method has disadvantages: 1. Steam The use of automobiles is expensive, and steam vehicles are frequently used; 2. The steam vehicle equipment takes a long time to prepare, which seriously reduces the work efficiency on site. It often takes a long time to dredge a well, and there are many wells, and the operation is time-consuming and laborious. At the same time, the staff spends a long time Working in a low temperature and windy environment can easily cause frostbite and bring great trouble to the work
