- Car rig
The vehicle rig has the characteristics of high concentration, convenient transition, quick installation and flexible operation, all of which can reduce drilling costs.
On - board rigs, when using chillers for cooling in winter, due to the low temperature requirements for cooling water, the cooling water system also needs to adopt electric heating and anti - freezing measures. The minimum temperature of the cooling water operated by the chiller is 10 °C. When the cooling tower is cooled for free, the operating temperature of the cooling water can be lower than 10 °C. The vehicle rig, that is to say, the project needs to maintain the temperature of the water medium in the cooling tower at around 10 °C.
