Arctic rigs are specially designed and manufactured cluster rigs for Arctic regions. Rigs are complete with winter thermo shelves, heating and venting systems, securing the stability work of rigs under low temperature environments. The temperature of the working environment is -45℃～+45℃ with a storage temperature of -60℃～+45℃. Polar rigs comply with GOST 12.2.141-99 and the requirements of the petroleum and natural gas industry security requirements ПБ 08-624-03.

According to the characteristics of the high cold environment, the material, lubrication seal, hydraulic transmission, electrical transmission control and so on to carry out a comprehensive characteristic design, the mechanical structure of the key parts are using low temperature resistant materials, for the lubricating oil box are using automatic temperature control heating device.

A variety of heating methods and parallel partition blocks are used for precise thermal insulation heating to ensure that the temperature on the drilling floor is ≥0℃ and the temperature in the insulation shelter is ≥10℃, so as to improve the heating efficiency.

The power supply system can be supplied by diesel generators or industrial power grids, and the two can be interchangeable.

Successful case: ZJ50DB Low-temperature Drilling Rig

The new generation of low-temperature drilling rig, integrating innovation, optimization and upgrading. It adopts a slide-rail type double-track moving structure. All modules of the drilling rig are placed on the track to meet cluster well operations. At the same time, the thermal insulation shed adopts a combination design, integrating the drill floor thermal insulation wall plates and the driller's cabin, and integrating the solid control area thermal insulation shed and the solid control tanks, which has a compact structure and is convenient for disassembly and assembly. This innovative design concept not only solves the problems of many modules, heavy weight, easy wheel derailment, and inconvenient installation of the insulation shed of the conventional train-type low temperature rig, but also reduces production and operation costs, achieving a win-win goal with customers.
