[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] Please refer to Figure 1-2 The embodiment of the utility model provides an ASR seismic survey instrument, comprising:

[0036] The main housing 1 has a receiving slot 11 formed on one side thereof;

[0037] A support mechanism 2, which can be opened and retracted and is disposed in the receiving groove 11, and is used to fix and support the main housing 1 in the well;

[0038] The driving mechanism 3 is arranged in the main housing 1 and is in driving connection with the supporting mechanism 2 to drive the supporting mechanism 2 to open or retract;

[0039] ASR detector 4, fixedly connected to the bottom end of the main housing 1;

[0040] The upper cable connection mechanism 5 is arranged at the top of the main housing 1;

[0041] The lower cable connecting mechanism 6 is arranged at the bottom end of the ASR detector 4 .

[0042] In this embodiment, in actual use, an ASR seismic survey instrument is arranged at a certain distance in the vertical direction, and adjacent ASR seismic survey instruments are connected by cables, which are connected to the ASR seismic survey instruments through an upper cable connection mechanism 5 and a lower cable connection mechanism 6, thereby ensuring the firmness of the connection. Each ASR seismic survey instrument is responsible for surveying seismic information within a certain range, and comprehensive monitoring of oil wells is achieved through a number of vertically distributed ASR seismic survey instruments.

[0043] When installing the equipment, each ASR seismic survey instrument is put into the oil well one by one. After the ASR seismic survey instruments form a vertical distribution with full coverage in the oil well, the driving mechanism 3 drives the supporting mechanism 2 to open and fix each ASR seismic survey instrument at a corresponding position in the well. After the equipment is installed, the seismic information at each position is surveyed by the ASR geophone.

[0044] The ASR seismic survey instrument of the present application is easy to install, reliably fixed, comprehensive in surveying, and accurate in surveying information, thus ensuring the safe operation of the oil well.

[0045] In a preferred embodiment, if Figure 1 and Figure 2 As shown, the main housing 1 is cylindrical, which makes it smoother to lower the device when placing it and to lift it up when removing it.

[0047] In this embodiment, the sealing sleeve ensures the sealing between the gear shaft 23 and the main housing 1 .

[0048] The driving mechanism 3 drives the gear shaft 23 to rotate, thereby driving the push arm 21 to swing through the side plate 22 fixedly connected to the gear shaft 23. When the push arm 21 swings outward, its bottom end abuts against the inner wall of one side of the oil well, fixing the main housing 1 to the inner wall of the other side of the oil well. When the push arm 21 swings inward, it is received in the receiving groove 11, releasing the fixed support to the main housing 1. The support mechanism 2 firmly fixes the main housing 1, improving the convenience of equipment installation.

[0049] Preferably, a supporting slope is provided on one side of the bottom end of the pushing arm 21 away from the main housing, thereby increasing the contact area between the bottom end of the pushing arm 21 and the inner wall of the oil well after the pushing arm 21 is opened, thereby improving the stability of the fixation.

[0057] In this embodiment, the cable passes through the first outer cone sleeve 56 and the first inner cone sleeve 57, so that the cable is pulled tighter and tighter, thereby improving the reliability of the cable connection.
