[0001] The present application relates to the field of oil seismic exploration technology equipment, and in particular to a tool for improving the receiving effect of hard surface geophones. Background Art
[0002] At present, there are two main ways to bury detectors in exposed rock formations. One is to find loose soil and pile it up in the exposed rock formation and bury the detector in the soil pile.

The second method is to fill the PVC pipe with loose soil in the exposed rock formation with better terrain, and then insert the detector.

[0023] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.
[0025] At present, there are two main ways to bury detectors in exposed rock formations. One is to find loose soil and pile it up in the exposed rock formation and bury the detector in the soil pile. If the surrounding area is severely washed away by rain and there is no loose soil, the detector is piled in the gravel with gravel. The second method is to fill the PVC pipe with loose soil in the exposed rock formation with better terrain, and then insert the detector.
[0026] At present, the main burial method for hard surfaces is body coupling. It is difficult to truly achieve body coupling (the detector is completely inserted into the rock layer) on hard surfaces, and there is no need to achieve body coupling. The main contradiction is to achieve good coupling and improve the receiving effect.
[0027] Regarding the above-mentioned related technologies, the inventors believe that for high, steep and complex surfaces, the objective conditions themselves are low signal-to-noise ratio areas, and there is no better burial method and coupling method, resulting in worse reception effect.
[0028] In order to be suitable for mountain seismic exploration of steep and complex surfaces, for large areas of exposed hard surface, and to improve the coupling between the detector and the earth, the present application provides a tool to improve the receiving effect of the hard surface detector.
[0029] The following is combined with Figures 1-3 This application is described in further detail.
[0030] The embodiment of the present application discloses a tool for improving the reception effect of a hard surface geophone. Figure 1 、 Figure 2 A tool for improving the reception effect of a geophone on a hard surface includes a connecting portion 1, a connecting member 1 being provided at the bottom end of the connecting portion 1, and the connecting portion 1 being connected to a detection end of the geophone via the connecting member 1. In the early stage, an electric drill is used to drill a hole in the rock. After the drill drill drills the hole, the rock becomes small, irregular particles. When the geophone is buried, the drilled hole must be backfilled with mud and sand.
[0031] The end of the connecting portion 1 facing away from the geophone is fixedly connected to a guide cone 2. This guide cone 2 extends into the drilled hole. Irregularly shaped small particles within the hole contact the sidewalls of the guide cone 2, forming a coupling effect. This increases friction between the geophone and the ground, causing it to vibrate synchronously with the ground's vibrations. Because friction is determined by the contact surface and normal pressure, if the cone remains unchanged, the contact surface between the cone and the ground increases, which also increases the roughness of the contact surface and the friction coefficient. Rotation increases the normal pressure, which in turn increases the normal pressure between the cone and the ground. This increases friction by increasing the contact surface, friction coefficient, and normal pressure.
[0032] The connecting part 1 comprises clamping surfaces 11 located on the outer side, a plurality of clamping surfaces 11 are arranged along the circumference of the connecting part 1, and the adjacent two clamping surfaces 11 abut against each other. The clamping surface 11 is a planar structure, and the clamping surface 11 is arranged to facilitate the rotation of the connecting part 1 by the operator, and then the connecting part 1 and the vertebral body part 2 are fixed on the detection end of the geophone.
[0033] Referring to Figure 2 The connecting part 1 comprises a locking screw hole 12 arranged on the side of the connecting part 1 away from the vertebral body part 2. The axis of the locking screw hole 12 is coaxially arranged with the center symmetry line of the connecting part 1, and the connecting part 1 is connected to the detection end of the geophone through the locking screw hole 12, so that the connecting part 1 can be replaced on the detection end of the geophone for different vertebral body parts 2.
[0034] In some embodiments, the minimum outer diameter of the connecting part 1 is 24 mm, the maximum outer diameter is 27.7 mm, the diameter of the locking screw hole 12 is 14 mm, and the hole depth of the locking screw hole 12 is 22 mm.
[0035] The vertebral body part 2 is a conical structure, and the diameter of the end of the vertebral body part 2 away from the connecting part 1 is smaller than the diameter of the end of the vertebral body part 2 close to the connecting part 1. The side wall of the vertebral body part 2 gradually increases from the end away from the connecting part 1 to the end close to the connecting part 1. The diameter of the end of the vertebral body part 2 close to the connecting part 1 is smaller than the outer diameter of the connecting part 1, and the end of the vertebral body part 2 close to the connecting part 1 is chamfered with the connecting part 1.
[0036] In some embodiments, the height of the vertebral body part 2 is 75 mm, and the diameter of the end of the vertebral body part 2 away from the connecting part 1 is 6.7 mm.
[0037] A fastening groove 21 is arranged on the outer side of the vertebral body part 2. The groove opening direction of the fastening groove 21 is arranged at an angle with the axis direction of the vertebral body part 2, so that the groove opening direction of the fastening groove 21 is not parallel to the direction of the vertebral body part 2 extending into the hole, and the friction between the vertebral body part 2 and the sand inside the hole is increased.
[0038] In some embodiments, the fastening groove 21 is a spiral structure, the spiral tooth shape of the fastening groove 21 is spiral R shape, and the groove cross section of the fastening groove 21 is arc-shaped groove. The coupling degree of the arc-shaped groove is higher than that of the triangular or trapezoidal groove during the rotation of the vertebral body part 2. If the trapezoidal or triangular groove is used, the large sandstone exceeding the specification of the trapezoidal and triangular groove will easily cause the geophone to be stuck during manual rotation, and it is difficult to completely bury the vertebral body. The coupling degree is not high due to the drilling. The arc-shaped small particle sand has good screening property during rotation, which is convenient for burying.
[0039] The groove depth of the fastening groove 21 gradually decreases from the end close to the connecting part 1 to the end away from the connecting part 1. The groove depth of the fastening groove 21 close to the connecting part 1 is 4 mm, and the groove depth of the fastening groove 21 away from the connecting part 1 is 2 mm.
[0040] The pitch of the fastening groove 21 is 5 mm, and the angle between the fastening groove 21 and the horizontal direction is not greater than 45°. The protruding part 22 is formed between the adjacent two fastening grooves 21 of the lead vertebra part 2, so that the protruding part 22 and the fastening groove 21 can be arranged in sequence. The crushed gravel can enter the inside of the fastening groove 21 and be limited by the protruding part 22. Through the arrangement of the plurality of fastening grooves 21 and the plurality of protruding parts 22, the coupling degree of the lead vertebra part 2 and the inner side wall of the hole is improved.
[0041] First, drill a hole through the electric drill; the drill bit is the maximum diameter of the vertebra, the electric drill is light and easy to carry, and one charge can drill 80-90 holes; the connecting part 1 is connected with the detection end of the detector through the locking screw hole 12, and the lead vertebra part 2 after connection is inserted into the hole drilled by the electric drill, so that the core component of the detector is not changed, and the replacement of the spiral R vertebra can be used to achieve good embedding in the exposed rock layer, improve the coupling degree of the detector in the exposed rock layer, and there is no need to separately purchase a special detector, thereby saving cost and increasing benefit.
