摘要： Techniques for evaluating physical aspects of a formation fluid from within a wellbore include changing at least one of a pressure on and a temperature of a sample of the formation fluid and transmitting at least one acoustic pulse through the fluid sample and analyzing acoustic information collected. Apparatus and methods for the evaluating involve using at least one acoustic transducer. Analyzing typically involves use of formulae that relate equation(s) of state and other properties for the fluid to a change in the sound speed in the fluid.

摘要： A method for detecting a change in a wellbore fluid includes estimating at least two pressure differences in the wellbore fluid and estimating a change in a density of the fluid using the at least two pressure differences. The density change may be estimated by the equation, ?p = ( ?Pbefore-influx - ?Pafter_?nflux ) / ( g x ?TVD ), wherein ?P is a fluid pressure difference between two points along the wellbore, p is a mean value of density of the fluid between the two points, g is gravity and ?TVD is a vertical distance between the two points. The method may include estimating a density change using an estimated inclination of the wellbore. An apparatus for estimating density changes includes at least two axially spaced apart pressure sensors. The sensor positions may be switched to estimate a correction term to reduce a relative offset between the two pressure sensors.

摘要： A method of determining properties of a formation fluid based on measurements of fluid sound speed, a measurement of fluid density, or both. The properties include compressibility, thermal conductivity, and gas oil ratio. The compressibility of a fluid is equal to the reciprocal of the product of the sound speed squared and fluid density. The density and the sound speed can be measured acoustically. The method further includes a manner of processing data including applying the Savitzky-Golay method and utilizing a variable thresholding technique.
