Detailed Description
The invention is described in further detail below with reference to the accompanying drawings.
As shown in fig. 1, the invention comprises a shaft 1, a flange 2, a plug 3, a water inlet pipe 4, a water outlet pipe 5, an inner pulley bracket 6 and a shaft bracket 7. The well bore 1 is cylindrical and made of a material with stable acoustic properties, and the inner diameter is larger than the maximum outer diameter of the acoustic instrument while drilling, and is the actual borehole size of the instrument working underground, and the actual borehole size generally comprises several specifications of phi 152mm, phi 216mm and phi 241 mm. Since the sonic instrument measures the sliding wave propagating along the well wall from the transmitting probe to the receiving probe, the detection depth is shallow, so the wall thickness of the well bore 1 can be thin, but in order to make the well bore 1 have enough strength, it can be thickened to be larger than 15mm. The length of the shaft 1 is larger than the distance between the transmitting probe and the receiving probe and smaller than the distance between the transmitting circuit and the receiving circuit, namely, when the instrument is calibrated and tested, the transmitting and receiving measurement and control circuit 9 is positioned outside the liquid filling shaft 1, so that online debugging can be performed.
In order to simulate the stratum with different hardness around the instrument when in underground operation, the shaft 1 can be made of glass fiber reinforced plastic, aluminum alloy, organic glass, PVC and copper, and the sound velocity range is 1000 m/s-8000 m/s. As a scale instrument, it is desirable to accurately measure the speed of sound of the wellbore material. The well bore material may be used to form a sample block in the shape of a quadrangular prism, a hexagonal prism or an eight prism, any two symmetry planes of the sample block forming a set of transmitting and receiving planes. And (3) adopting standard longitudinal wave and transverse wave ultrasonic transducers to emit sound waves at any emitting surface, passing through a sample block to reach the transducer at the corresponding receiving surface, measuring the time t used for the sound waves to reach the receiving surface from the emitting surface within a fixed distance L by an ultrasonic analyzer, calculating the sound wave propagation speed under the current medium, and measuring all emitting and receiving planes to obtain the average sound velocity.
The flange plates 2 are respectively processed at two ends of the shaft 1, the boss-shaped plugs are tightly and tightly arranged on the flange plates by bolts, and the transducer and the sound insulator are required to be positioned in the liquid filling shaft 1 during instrument calibration and testing, so that the water inlet pipe 4 and the water outlet pipe 5 with valves are arranged on the boss surfaces of the plugs and are used for water inlet and outlet in the shaft 1.
When the instrument enters and exits the well bore 1, a certain support is needed, and meanwhile friction between the instrument and the well bore 1 is reduced. The inner pulley support 6 is made of stainless steel or copper, has a shape of a circular arc smaller than a semicircle, and has the same radian as that of the inner wall of the shaft 1. At least 4 mounting holes are symmetrically formed in the surface of the inner pulley bracket 6, a rolling shaft is fixedly mounted, the diameter of the rolling shaft is larger than the thickness of the inner pulley bracket 6, and accordingly the rolling shaft is contacted with the inner wall of the shaft 1 and the outer wall of an instrument respectively and can slide along the inner wall of the shaft 1.
The working process of the invention is as follows: the shaft 1 is horizontally placed on the shaft support 7, and at least 3 support points are provided for avoiding deformation of the shaft, and are uniformly and stably supported at the two ends and the middle of the shaft 1. The instrument is placed on a pulley cradle 6 and the axes of the well bore 1 and the instrument should be in line. The instrument is pushed into the well bore 1 through the inner pulley support 6, and at least two inner pulley supports 6 are placed in the well bore 1 in order to support the instrument at least at two points all the time in the pushing process and reduce the friction between the instrument and the well bore. Pushing one end of the instrument to a proper position, enabling the transmitting and receiving measurement and control circuit 9 to be positioned outside the shaft 1, enabling the acoustic drill collar 8 provided with the transducer and the sound insulator to be positioned in the shaft 1, connecting the water inlet pipe 4 with a water source after installing the sealing sleeve between the plugs 3 at two ends and the instrument, opening the valve of the water inlet pipe 4, closing the valve of the water outlet pipe 5, filling the shaft 1 with water and closing the valve of the water inlet pipe 4, and then scaling and testing the instrument. If the measurement and control circuit 9 is to be debugged, the protection cylinder of the circuit can be detached, and real-time online debugging is performed. After the scale test is finished, the valve of the water outlet pipe 5 is opened, and the water in the shaft is emptied. The instrument is removed from the wellbore 1 in the reverse of the above.
