Water-free drilling sound wave detection and water pressure test integrated device

Abstract

The invention provides a water-free drilling sound wave detection and water pressure test integrated device. The water-free drilling sound wave detection and water pressure test integrated device comprises a water supply device, a water stop device and a pressing device, wherein the water supply device comprises a constant-pressure water pump, a water inlet pipe, a water guide pipe and a floral pipe; the water stop device comprises an upper plug and a lower plug; at least three sound wave transceivers are fixedly arranged on the side wall of the floral pipe at equal intervals so as to realizesound wave detection; and the pressing device comprises a pressing pipe, water is injected through the water guide pipe, and the water enters a test section through the floral pipe so as to realize awater pressure test. The characteristic that water injection needs to be carried out in sound wave detection and water pressure test is ingeniously utilized, and the sound wave transceivers used for sound wave test are arranged on the side wall of the floral pipe; after water is injected into the test section, sound wave receiving and transmitting control can be carried out on each sound wave transceiver, so that sound wave detection is realized; meanwhile, the water permeability or the permeability coefficient can be calculated by measuring parameters such as the length of the test section, the radius in the hole and the water amount of the test section; and the operation is convenient, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of geological survey, in particular to an integrated device for sound wave detection and water pressure test of anhydrous drilling. Background technique [0002] At present, in order to provide basic data for evaluating the permeability characteristics and integrity of rock mass, it is necessary to drill holes in the rock mass, and conduct acoustic wave testing and pressure water tests on the drilling holes. Put it into the air bag or water belt, sink the air bag or water belt to the depth of the drill hole to be measured, pressurize the air bag or water belt to make it seal with the hole wall, and the ground (ultrasonic) acoustic wave controller controls the acoustic wave transmitter Transmit (ultrasonic) sound waves, and the fluctuations are transmitted to the sound wave receiver through water and rock mass. Using the time difference between sending and receiving and the sound wave transmission distance, t...

Problems solved by technology

Acoustic detection and pressure water test are two commonly used testing methods in the field of geological survey. They need to be detected by two sets of independent equipment, and the workload is heavy. How to use a set of equipment to perform acoustic detection in anhydrous drilling and at the same time realize Pressurized water test will greatly reduce the workload of drilling tests and improve work efficiency
