摘要： A method of determining a dry proppant concentration in a fracturing fluid includes combining a wet proppant with a carrier fluid in a mixer to form the fracturing fluid. The dry proppant concentration of the fracturing fluid leaving the mixer is determined using a moisture content of the wet proppant entering the mixer, wherein use of the moisture content prevents overestimation of the dry proppant concentration. The method can be preformed using a system for injecting fracturing fluid into a borehole, the fracturing fluid including a carrier fluid mixed with a wet proppant including a dry proppant dampened with a dampening liquid. The system includes a mixer operable to receive and mix the carrier fluid and the wet proppant to form the fracturing fluid, a frac pump operable to inject the fracturing fluid into the borehole, and a control system comprising a processor operable to receive a moisture content of the wet proppant before being mixed with the carrier fluid and programmed to determine a dry proppant concentration of the fracturing fluid formed in the mixer using a moisture content of the wet proppant, wherein use of the moisture content prevents overestimation of the dry proppant concentration.

摘要： A device for generating bubbles or droplets may include a cavity comprising a first pressurized phase, at least one input capillary of a second phase, and an output capillary coaxially aligned with the at least one input capillary. The opening of the tip of the at least one input capillary has an internal diameter of less than half the internal diameter of the output capillary. The cross section of the cavity may be selected so that, in use, the average speed field in the cavity is quasi-static.

摘要： Methods and apparatus are disclosed relating to mixing fluids in welding-type equipment. In some examples, a welding-type power supply (and/or wire feeder) may include multiple fluid paths through which to provide fluid from multiple fluid reservoirs to multiple welding-type tools. The power supply may be configured to automatically control fluid flow rates through the fluid paths via proportional valves. Further, the welding-type power supply may be configured to allow and/or prohibit mixing of fluids from different flow paths via control of various valves.

摘要： A technique facilitates mixing of fluids for use in well treatment operations. According to an embodiment, a dry powder material, e.g. a friction reducer, may be thoroughly mixed into fluid or fluids associated with a well treatment operation. The powder material is combined with liquid, e.g. water, via a series of Venturi mixers arranged to thoroughly mix the materials. In some applications, the Venturi mixers are mounted on a modular unit which is readily moved to a desired wellsite. Additional modular units may be added to increase the amount of product being mixed according to the demands of a given well treatment operation, e.g. a hydraulic fracturing operation.
