Abstract

A system and method for rheology measurements. The system may comprise a conduit; an ultrasound transmitter positioned to direct ultrasound pulses into the conduit; an ultrasound receiver positioned to receive sound waves from the conduit; a pump fluidically coupled to the conduit; and a heat exchanger fluidically coupled to the conduit. The method may comprise drawing a sample of a treatment fluid into the rheology measurement system; pressuring the sample of the treatment fluid; adjusting temperature of the treatment fluid; directing ultrasound pulses into the treatment fluid while the treatment fluid is flowing through the rheology measurement system; measuring sound waves reflected by the treatment fluid; and determining a velocity profile of the treatment fluid based at least on the measured sound waves.

Claims

1. A system for rheology measurements comprising:

a conduit;

an ultrasound transmitter positioned to direct ultrasound pulses into the conduit;

an ultrasound receiver positioned to receive sound waves from the conduit;

a pump fluidically coupled to the conduit; and

a heat exchanger fluidically coupled to the conduit.

2. A system according to claim 1, wherein the ultrasound transmitter and the ultrasound receiver are a single element.

3. A system according to claim 1, wherein the ultrasound transmitter and the ultrasound receiver are disposed on opposite sides of the conduit.

4. A system according to claim 1, wherein the ultrasound transmitter and the ultrasound receiver are disposed on the same side of the conduit.

5. A system according to claim 1, wherein the pump is a pulse dampened diaphragm pump.

6. A system according to claim 1, wherein the heat exchanger is a peltier device.

7. A system according to claim 1, wherein the system further comprises a flow straightening device disposed in the conduit.

8. A system according to claim 7, wherein the flow straightening device comprises a plurality of vanes disposed in the conduit.

9. A system for rheology measurements comprising:

a conduit;

an ultrasound transmitter positioned to direct sound waves into the conduit;

an ultrasound receiver on an opposite side of the conduit from the ultrasound transmitter and positioned to receive sound waves from the conduit;

a pump fluidically coupled to the conduit;

a heat exchanger fluidically coupled to the conduit; and

vanes disposed in the conduit.

10. A system according to claim 9, wherein the heat exchanger is a resistance band heater.

11. A method of operating a rheology measurement system comprising:

drawing a sample of a treatment fluid into the rheology measurement system;

pressuring the sample of the treatment fluid;

adjusting temperature of the treatment fluid;

directing ultrasound pulses into the treatment fluid while the treatment fluid is flowing through the rheology measurement system;
