Embodiment Construction

[0046] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0047] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may a...

Abstract

The invention provides a vertical shear two-component transverse wave ultrasonic transducer and a preparation method thereof. The vertical shear two-component transverse wave ultrasonic transducer comprises a dual-component transverse wave transducer vibrator, a metal shell and a double-wire connector. The dual-component transverse wave transducer vibrator is arranged in the metal shell, and the double-wire connector is arranged on the outer wall of the metal shell; the dual-component transverse wave transducer vibrator comprises an insulating lining pipe, a dual-component shearing unit and a backing insulating sound absorption block, wherein the dual-component shearing unit and the backing insulating sound absorption block are accommodated in the insulating lining pipe, and the backing insulating sound absorption block is arranged on the upper surfaces of the dual-component shearing unit. The vertical shear two-component transverse wave ultrasonic transducer can simultaneously obtain two transverse wave speeds in the mutually perpendicular direction, so that the anisotropy of rock or other composite materials can be detected under the environment that the transducer is not easy to rotate.

Description

technical field [0001] The invention relates to the technical field of rock or other composite material anisotropy detection instruments, in particular to a vertical shear two-component transverse wave ultrasonic transducer capable of operating in a frequency range of 0.2-2 MHz and a preparation method thereof. Background technique [0002] The statements in this section only provide background information related to the present disclosure and may not constitute prior art. [0003] With the demand for various reservoir rock velocity anisotropy parameters in seismic exploration, more and more attention has been paid to the test of shear wave velocity. However, when simulating shear wave tests on rocks under underground pressure environment, it is difficult to simultaneously obtain shear wave velocities in two mutually perpendicular directions under the same experimental environment. [0004] When testing the rock velocity in a pressure vessel under a simulated underground pr...
