US Patent:

20200278326, Sep 3, 2020

Filed:

May 19, 2020

Appl. No.:

16/878088

Inventors:

- Houston TX, US
Chung Chang - Houston TX, US
Clinton Keith Bates - Kingwood TX, US

Assignee:

Halliburton Energy Services, Inc. - Houston TX

International Classification:

G01N 29/24
G01H 3/00
G01N 29/22
G01V 1/52

Abstract:

An acoustic receiver and method for acoustic logging. The acoustic receiver comprises a housing and a sensor subassembly, which is located within the housing. The sensor subassembly comprises a mount and a cylindrical piezoelectric crystal coupled to the mount. The sensor subassembly also comprises an isolation ring positioned between one of the ends of the cylindrical piezoelectric crystal and the mount. The isolation ring directly engages the crystal and the mount. The method of acoustic logging comprises receiving an acoustic signal using an acoustic receiver, which comprises a cylindrical piezoelectric crystal coupled to a mount without an adhesive material. The method also comprises converting the acoustic signal into an electrical signal by the cylindrical piezoelectric crystal and transmitting the electrical signal to a processor via a conductor coupled to the cylindrical piezoelectric crystal.
