Downhole local solid particles counting probe, production logging tool comprising the same and sand entry investigation method for hydrocarbon wells |
| abstract |
A downhole local solid particles counting probe ( 1 ) for counting solid particles ( 101 ) in a fluid ( 100 ) present in a hydrocarbon well in production comprising:n an elongated and flexible protective tube ( 2 ) defining an internal cavity ( 5 ) terminating by a membrane wall ( 3 ) defining a tip ( 4 ), the protective tube ( 2 ) and the membrane wall ( 3 ) isolating the internal cavity ( 5 ) from the fluid ( 100 ) of the hydrocarbon well, the protective tube ( 2 ) and membrane wall ( 3 ) are made of metal or metal alloy and have a thickness (ei) such as to resist to the downhole hydrocarbon well pressure; a passive acoustic sensor ( 6 ) mounted inside the internal cavity ( 5 ), the passive acoustic sensor ( 6 ) having a front side ( 7 ) mechanically coupled on the membrane wall ( 3 ) of the tip ( 4 ); a characteristic dimension of the passive acoustic sensor ( 6 ) is similar to solid particles ( 101 ) average characteristic dimension, ranging from 0.5 mm to 1.5 mm, and a characteristic dimension of the membrane wall ( 3 ) defining the tip ( 4 ) ranges from 1 mm to 2 mm; and the passive acoustic sensor ( 6 ) is arranged to detect acoustic waves ( 30 ) generated by solid particles ( 101 ) impacting the membrane wall ( 3 ) defining the tip ( 4 ) so as to resolve an individual impact from a single solid particle and to produce a signal representative of a count of solid particles. |
