Problems solved by technology

[0005] The present invention is to solve the technical problem that the structure of the geophone in the existing well does not help to get out of the well quickly, and provides a method of using the geophone to combine and install the corresponding electronically controlled vibrating rod to generate resonance vibration in the mud at the bottom of the well. The mud settled at the bottom of the well is mixed with clean water again, so as to reduce the resistance of the mud stuck in the well, so that the combination of geophones can quickly solve the problem of stuck wells under the auxiliary lifting of the wellhead.

Embodiment Construction

[0027] Referring to the accompanying drawings, the present invention will be further described in detail with specific embodiments.

[0028] like figure 1 and 2 As shown, the geophone in the anti-jamming well is a cylindrical structure as a whole, which is divided into electronically controlled vibrating rod 7, connector unit 6, geophone fixing unit 4, load-bearing block 3, high-strength lifting rope 2 and multi-core cable 1. The structure of the electronically controlled vibrating rod 8 is common knowledge, and it is provided with a vibrating rod body 8 .

[0029] A single-component or multi-component geophone core 5 can be installed in the geophone fixing unit 4 as required, and the multi-core cable 1 penetrates into the geophone fixing unit 4 through the middle hole of the load-bearing block 3 . At least one set of wire cores in the multi-core cable 1 is connected to the detector core 5 , and at least one pair of wire cores is extended to the connector unit 6 through the...

Abstract

The invention relates to an anti-sticking borehole detector and solves a technical problem that the structure of a borehole detector in the prior art does not contribute to rapid borehole tripping. The detector comprises a detector fixing unit and a multi-core cable, wherein a detector core is arranged in the detector fixing unit, the multi-core cable is connected with the detector core, the detector fixing unit is connected with an electric control vibration rod through a connecting body unit, and a core of the multi-core cable is connected with a motor lead in the electric control vibrationrod through a connecting cable. The invention can be applied to the technical field of a detector.

Description

technical field [0001] The invention relates to a geophone, in particular to an anti-jamming geophone in a well. Background technique [0002] In onshore oil and gas exploration technology, in order to obtain underground reflected wave data more realistically, the method of placing geophones in deep wells is often used at present. This method can obtain different signal waves by transforming different excitation modes after the combined positioning of the geophones, which saves construction cost and time to a certain extent. [0003] The patent number is 201721730545.3, and the name is a Chinese utility model patent for an air-controlled downhole geophone, which discloses a geophone used in a well. The patent number is 201220016417.3, and the name is a Chinese utility model patent for a multi-channel geophone string in a well, which discloses a geophone string in a well. [0004] However, at the current stage, most domestic customers are conducting exploration at the foref...
