Abstract: The total amount of electric power in an oilfield power station is the restriction in increasing the production. The rated power of solarT130 turbine generator set is 15.3 KVA,and the current load can only be about 9.5 MW,which is a big gap from the rated load capacity of the turbine,so the load rising space of the turbine can be further improved. In order to improve the load capacity of the turbine in the oilfield,the following problems must be solved：① The unreasonable set value of the VCB switch integrated current limits the load of the turbine to 11.3 MW;② The current turbine bearing 1# vibration is high,and the vibration value increases rapidly to the alarm value when it is higher than 10 MW;③ Insufficient supply of natural gas fuel,turbine load rising needs to increase the supply of natural gas,and the natural gas in the existing production process cannot be collected as fuel. Through a series of equipment data accounting,as well as measures such as on-site process modification and vibration resolution,the bottleneck of turbine load rising was finally resolved,achieving a stable load of 10.5 MW and a maximum load of 14 MW for the turbine. These measures not only maximize the utilization of power,but also reduce the energy waste of natural gas. In addition,the emergency generator is connected to the main power grid,providing certain support for the overall power optimization,production improvement,and production increase of the oilfield.
