Recently, the 30L chain drive network electric drill rig independently developed by Shengli Drilling Institute carried out on-site test in the Ying-1 oblique 70 well constructed by the 30861 team and achieved success. This is another major technological breakthrough in the transformation of the grid drilling rig after the success of the on-site test of the electric drive network electric drill in 2006.
Since last year, the oilfield has undergone the transformation of the electric drive rig network. The drilling institute has completed the project and achieved success. It has successively transformed 8 units and the application effect is good. Since the beginning of this year, the drilling institute has started to carry out network power transformation for the chain drive drilling rig. Compared with the transformation of the electric drive rig network, the transformation of the chain drive rig network is much more difficult. Based on the electric drive rig network transformation technology, the drilling institute solved the development of high-power variable-speed fluid coupling, the start and stop of high-power motor industrial power grid, the motor unit with the original drilling rig and the car box, and the power system with the drilling rig. A series of problems such as drilling technology support, successfully replaced the original diesel power unit with electric power units, and achieved a breakthrough in the transformation of mechanical drilling machine network.
The electric drill was put into operation in Yingling 1-Xing 70 well on April 22 and completed on June 9. The grid system was safe, reliable and stable during the entire drilling process, and no abnormalities occurred.
