Description
Technical Field
[0001] The present invention belongs to the technical field of seismic exploration, and in particular relates to a micro-log data acquisition device in seismic exploration. Background Art
[0002] In the field production of micro-log in seismic exploration, the existing method for collecting data in micro-log of seismic exploration is to connect a dedicated acquisition computer to multiple in-well geophones in the well, and then use a ground excitation device to collect data step by step. However, in some mountainous and plateau areas, after collecting data at the current point, it is necessary to move to the next point for collection, which is very inconvenient, with low production efficiency and requiring a large amount of manpower. The traditional method of collecting micro-log data with a wired digital seismograph can no longer meet the production requirements in complex terrains. With the progress of science and technology and the development of node instruments, various methods for collecting micro-log data have been envisioned, replacing the traditional method of conventional micro-log data collection, greatly shortening the field production cycle of micro-log and improving production efficiency.
[0003] Currently, the conventional method for collecting micro-log data is that the micro-log instrument carries multiple geophones and lowers the multiple geophones into the well one by one. The existing micro-log instruments are large in size, high in weight, and cumbersome to operate, and cannot cope with complex terrains. In the actual field production of micro-log, the bulky micro-log instruments have more or less some drawbacks in collecting micro-log data in complex terrains, and cannot meet the production status, causing great limitations to the field production of micro-log in complex terrains. Therefore, in order to overcome the deficiencies of the existing micro-log data acquisition device in seismic exploration, a micro-log data acquisition device in seismic exploration is provided herein.

A timer 16 is fixedly installed on the top of the front end of the movable support 6.
[0016] On the basis of the above structure, through holes are provided at both left and right ends of the cross bar 4 and at the four right angles of the bottom frame 5.
[0017] In this embodiment, by using the through hole structures provided inside the cross bar 4 and the bottom frame 5, it is convenient to use a dowel to position the cross bar 4 and the bottom frame 5 on the soil surface.
[0018] On the basis of the above structure, an indication mark 7 is inlaid and fixed on the outer wall of the front bottom of the movable support 6. The indication mark 7 is an inverted triangle structure. A scale 15 is inlaid on the upper surface of the front end of the bottom frame 5. The indication mark 7 is located above the scale 15.
[0019] In this embodiment, by using the mutual cooperation of the indication mark 7 and the scale 15, it is convenient to accurately control the distance between the movable support 6 and the micro-log.
[0020] On the basis of the above structure, the driving component 8 includes a horizontal shaft 81, a driving motor 82, a disc 83 and a guiding groove 84. The horizontal shaft 81 is mounted on the inner side of the middle part of the movable bracket 6 through bearings. The horizontal shaft 81 is rotatably connected to the fixed rod 10. The driving motor 82 is fixedly installed on the outer wall of the rear end of the movable bracket 6. The output shaft of the driving motor 82 is fixedly connected to the rear end of the horizontal shaft 81. Discs 83 are fixedly sleeved on the outer sides of both ends of the horizontal shaft 81. The two discs 83 are symmetrically arranged front and back with respect to the movable bracket 6. Guiding grooves 84 are formed on the sides of the two discs 83 close to each other.
[0021] On the basis of the above structure, the guiding groove 84 is in a water-drop shape. The guiding groove 84 includes an annular section and a V-shaped section. Its V-shaped section is communicated with the annular section. The center of its annular section is located on the horizontal center line of the horizontal shaft 81.
[0022] On the basis of the above structure, the knocking component 9 includes a vertical pipe 91, a horizontal column 92, a weight 93 and an iron disc 94. The vertical pipe 91 is sleeved on the outer side of the square rod 11 in a clamping and sliding manner. Horizontal columns 92 are symmetrically fixed on the outer wall of the top end of the vertical pipe 91. A weight 93 is fixedly installed at the bottom end of the vertical pipe 91. An iron disc 94 is arranged directly below the weight 93. The iron disc 94 is placed on the ground.
[0023] In this embodiment, when the driving motor 82 is started to control the synchronous rotation of the horizontal shaft 81 and the disc 83, when one end of the horizontal column 92 is located in the annular section of the guiding groove 84, the knocking component 9 is stationary. When one end of the horizontal column 92 is located in the V-shaped section of the guiding groove 84, as the disc 83 rotates, it can push the horizontal column 92 to drive the vertical pipe 91 and the weight 93 to quickly lift and lower once, thereby causing a hammer blow to the iron disc 94. During the uniform rotation of the disc 83, intermittent knocking on the iron disc 94 can be realized. And through the vertical pipe 91 clamped and slid on the square rod 11, it is convenient to improve the lifting stability of the weight 93 during the knocking process.
[0024] On the basis of the above structure, the end of the horizontal column 92 away from the vertical pipe 91 is guided and slidably located in the guiding groove 84. The weight 93 and the iron disc 94 are connected in series in the same circuit with the timer 16. The model of the timer 16 is RTM3.
[0025] In this embodiment, when the weight 93 moves down and contacts the iron disc 94 for hammering, the timer 16 is energized and inductive to record the knocking time.
[0026] The working principle of the present invention is as follows: First, a micro-logging well is dug at a specified position on the soil ground. Subsequently, the nodal seismograph 1, the cross bar 4 and the bottom frame 5 are arranged as Figure 1They are successively installed on the left, middle, and right sides of the micro-logging well as shown. Subsequently, the external geophone string 3 connected to the nodal seismograph 1 through the connecting wire 2 is lowered into the micro-logging well, and the nodal seismograph 1 is powered on. At the same time, the iron disc 94 is embedded on the ground and directly below the weight 93. The drive motor 82 is started to control the horizontal shaft 81 to drive the disc 83 to rotate at a constant speed. When one end of the cross-column 92 is located in the annular section of the guiding groove 84, the knocking assembly 9 is stationary. When one end of the cross-column 92 is located in the V-shaped section of the guiding groove 84, as the disc 83 rotates, it can push the cross-column 92 to drive the vertical pipe 91 and the weight 93 to quickly lift and lower along the square rod 11 once, thus causing a hammer blow to the iron disc 94. During the constant rotation of the disc 83, intermittent knocking on the iron disc 94 can be achieved. When the weight 93 contacts the iron disc 94, the timer 16 is energized and inductive to record the knocking time. The seismic wave generated after the knocking generates a signal through the external geophone string 3 and is recorded and stored by the nodal seismograph 1. Using the time recorded by the timer 16 to intercept the data volume recorded by the nodal seismograph 1, the micro-logging well record can be obtained; The servo motor 12 can also be started to control the rotation of the lead screw 13, so as to control the movable bracket 6 to move leftward along the guide rod 14. At the same time, the position of the iron disc 94 is correspondingly adjusted to facilitate adjusting the distance between the knocking position and the micro-logging well. The distance can be accurately controlled by using the indicating mark 7 and the scale 15, which is convenient for quickly moving to the next observation point and obtaining multiple groups of data, and the data accuracy is higher; Compared with the prior art, the device has a simple structure, is easy to operate, is convenient to use in complex terrains, has high data acquisition efficiency, is beneficial to the field construction production of micro-logging wells, and saves production costs; It should be specifically noted that the nodal seismograph 1, the external geophone string 3, the drive motor 82, the servo motor 12, and the timer 16 in this device are all existing devices, and the circuit layout among the weight 93, the iron disc 94, and the timer 16 are all existing mature technical means, so they will not be described in detail.
