Abstract
A system for stimulating oil or gas production from a wellbore includes a hydraulic fracturing pump unit having one or more hydraulic fracturing pumps driven by one or more electrical fracturing motors, a variable frequency drive (VFD) controlling the electrical fracturing motors, a fracturing pump blower unit driven by a blower motor, and a fracturing pump lubrication unit having a lubrication pump driven by a lubrication motor and a cooling fan driven by a cooling motor. The system may further include a blender unit and a hydration unit. A system control unit may control the operational parameters of the system.
Claims6
A system control unit for use with a system for stimulating oil or gas production from a wellbore, the system control unit comprising:
- (a) a hydraulic fracturing pump unit controller configured to control a hydraulic fracturing pump unit having one or more hydraulic fracturing electrical motors, the hydraulic fracturing pump unit controller comprising
- (i) a hydraulic fracturing pump controller configured to control a hydraulic fracturing pump;
- and
- (ii) a hydraulic fracturing blower unit controller configured to control a hydraulic fracturing pump blower unit;
- and
- (iii) a hydraulic fracturing lubrication unit controller configured to control a hydraulic fracturing pump lubrication unit;
- and
- (b) a hydraulic blender unit controller configured to control a hydraulic blender pump unit having one or more hydraulic blender electrical motors, the hydraulic blender pump unit controller comprising
- (i) a blender control unit for controlling the operation of one or more blender units,
- (ii) a blender slurry power unit (SPU) pump control unit for controlling the operation of one or more blender SPU units,
- (iii) a blender SPU blower control unit for controlling the operation of one or more blender SPU blower units, and
- (iv) a blender blower control unit for controlling the operation of one or more blender blower units;
- and
- means for controlling selection of active pumps and for setting operating parameters of the active pumps.
