METHOD FOR DETERMINING THE ACOUSTIC CHARACTERISTICS OF A MUD FILTER CAKE |
| 摘要 |
At least one acoustic sensor registers a pressure response to a low-frequency non-oscillating pressure signal generated in a borehole by at least one source. At least one characteristic of a transient process of pressure change is determined from the registered signal. A thickness of a mudcake is determined. Then, based on the values received, a mudcake piezoconductivity or a fluid mobility or both are determined. |

1. A method for determining mudcake acoustic characteristics in a borehole, the method comprising:
registering by at least one acoustic sensor a response to a low-frequency non-oscillating pressure signal generated in a borehole by at least one source; determining from the registered signal at least one characteristic of a pressure change transient process; determining a thickness of a mudcake; and determining based on values obtained a piezoconductivity of the mudcake, a fluid mobility, or both. |
