On April 16, four SXJ550 workover rigs, independently developed by SOFE, were exported to Indonesia.

In the construction of oil and gas exploration and development, oil and gas wells are prone to failure in the process of self injection, pumping or water and gas injection, resulting in oil and gas production reduction or even shutdown. At this time, workover rig maintenance is needed. SXJ550 workover rig has strong power, the rated power of drawworks is 550 horsepower, adopts heightening derrick and seven-axle heavy-duty cross-country chassis, and integrates all well site equipment layout design. Its reliability and environmental adaptability are widely recognized by users at home and abroad. It is one of SOFE’s best-selling truck-mounted workover rigs. 

Over the years, SOFE adheres to the principle of customer-centered and value creation , strengthens the innovation drive, and vigorously promotes the independent research and development of truck-mounted workover rig in high temperature, extreme cold, high altitude and other adverse weather conditions. Now, SOFE can provide truck-mounted workover rig with maximum rated 1000 horsepower drawworks, which can be applied in various oilfield operating environments at home and abroad.

For offshore workover rig, each unit should be specifically designed according to different offshore platform layout and interface. In the face of large volume, length and width of large structural parts of offshore workover rig, and difficulty in fixing heavy trucks, we refitted the vehicles of logistics companies and welded special fixed seats to ensure that the equipment parts were firmly bound and transportation safety. At the same time,we strengthen the safety inspection on site, optimize the hoisting operation process, and strive to improve the operation efficiency. Since 2019, SOFE has developed various offshore workover rigs, such as HXJ135, HXJ180 and HXJ225, named after its maximum tonnage, which have been delivered to the offshore market successively.
