Definitions
- Figure 1 shows a typical wellsite configuration 100 for a primary cementing operation.
- a cementing head 101 is situated on the surface, and a casing string 103 is lowered into a borehole 102.
- the casing string interior fills with drilling fluid 108.
- the casing string is centered in the borehole by centralizers 104 attached to the outside of the casing string.
- Centralizers are placed in critical casing sections to prevent sticking while the casing is lowered into the well. In addition, they keep the casing string in the center of the borehole to help ensure placement of a uniform cement sheath in the annulus between the casing and the borehole.
- Figure 5 is an illustration of pressure waves in a wellbore.
- Figure 6 is an illustration of resonant and anti-resonant zones in pressure waves as a droppable object travels down casing.
- Figure 7 is an example of a plug depth as a function of the internal casing volume.
- Figure 8 illustrates the change of surface pressure amplitude and periodicity resulting from a top plug entering a region of larger inside casing diameter during a cementing operation.
- Figure 9 shows measured data versus model predictions as a plug travels down casing and passes through a region of larger inside casing diameter during a cementing operation.

Abstract
La position d'un objet décrochable (par exemple, un bouchon ou une flèche de cimentation) à l'intérieur d'un corps tubulaire (par exemple, une colonne de tubage) peut être déterminée par analyse de signaux acoustiques harmoniques générés par l'objet décrochable lorsqu'il passe à travers le corps tubulaire. Les signaux acoustiques harmoniques se présentent sous la forme d'ondes de pression. Les données de pression sont enregistrées par un système d'acquisition de données de pression et traitées mathématiquement pour estimer un temps de déplacement bidirectionnel des signaux acoustiques harmoniques, et déterminer la vitesse de propagation de signal acoustique, ce qui permet de déterminer la position de l'objet décrochable.
