Development Of An Advanced Gas Turbine Driven High-Speed Centrifugal Pump For Injection Services
Abstract
The high-speed centrifugal pump dealt with herein has been designed principally for applications in high-pressure injection for enhanced oil recovery. To assure the high output flexibility necessary for this service, the capability of varying the speed over a wide range was set as a main feature. For this purpose, a two-shaft gas turbine was chosen as a primary driver. Major design objectives were compactness, simplicity, and reliability. For achievement of the objectives, the direct coupling of the pump to the gas turbine as over 10,000 cpm, without gear, was set as a main goal. These primary objectives were associated with the request for modularity, ease of maintenance, high rotordynamic stability at all speeds, and good suction characteristics, to limit boosting requirements. A major support to this development was provided by high speed centrifugal compressor technology, from which design criteria and resources were applied to hydraulic and rotordynamic designs. A number of construction features, well proven on high pressure compressors, were implemented on this pump, through appropriate tailoring to the specific design objectives. Testing at full power and speed of a complete high speed pump and gas turbine set demonstrated satisfactory agreement of the actual performance with the related design objectives.
