Shengli oilfield Highland petroleum equipment Co., Ltd has been researched and developed brand-new cryogenic rigs on the basis of general drilling rigs. In consideration of cold weather’s effect on metal structural parts, rubber parts, electric elements, signal elements, fluid media, manufacturing processes and operating environments, we have taken some feasible measures according to Russian oilfield condition to make the rigs suitable for -45℃ environment. To optimize drilling rigs design, a lot of new measures, new materials and new processes are adopted. The dual mode, including heating system and good low temperature property of materials, will ensure rigs safety and operation convenience.

Main feather:

1.Forcefull power system ensures drilling rigs high driving power demand;
2.Strong bearing capacity and transmission capacity ensure the rigs safe and reliable operation;
3.The derrick mast is suitable for top drive;
4.Auxiliary brake ensures drawworks system reliability and safety;
5.More sustained and suitable drilling floor with wide floor;
6.Construction is full optimized design, and special windproof is installed;
7.Main load supporting parts adopt a large number of high-performance cryogenic materials, and via low temperature welding assess;
8.Key components and valve gates meet the low-temperature requirement and via low temperature welding assess;
9.Special rubber parts, seals, hose and so on meet the low-temperature requirement and via low temperature welding assess;
10.Bearable the cryogenics material and local heating system are available to improve the operation environment as well;
11.Using the specialty fuel oil to adapt to low temperature environment;
12.Meeting the requirements of -45℃ operation and -60℃  conservation.
