Recently, Nanyang Erji Petroleum Equipment (Group) Co., Ltd. developed two technologies for oil drilling equipment used for semi-drilling drilling rigs and drilling fluid delivery systems. It was granted a national invention patent, which was achieved this year by Nanyang Erji Group in terms of technology patents. With the two new achievements, the company has now obtained 14 national invention patent authorizations.
According to reports, drill rigs manufactured using patented technology for semi-dragging drilling rigs for oil drilling equipment have the advantages of easy disassembly and assembly, freedom from transportation restrictions, rapid movement, and adaptation to low temperature environments. The drilling fluid delivery system patented technology utilizes a special dual-pipe design, which requires no downtime in the maintenance of equipment, piping, and valves. It can be switched to allow another line to operate.
