Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] like figure 1 As shown, a high-temperature-resistant driving mechanism of a geophone in an oil well mainly includes a rear cover 1, a heat insulation layer 2, a reducer 3, a sleeve 4, and a driving motor 5, and there are five parts in total.

[0022] The heat insulation layer 2 is attached to the inner surface of the sleeve 4; the drive motor 5 and the reducer 3 are installed in the sleeve 4; the drive motor 5 and the reducer 3 are driven and connected; the reducer shaft extends out of the sleeve from one end of the sleeve 4 Connect the detector driving mechanism; the back cover 1 seals the sleeve from the other end of the sleeve 4, and protects the drive motor in the sleeve. The main functional parts of the present invention are the driving motor 5 and the speed reducer 3 .

[0023] The driving motor adopts a small DC brushed motor, the rated voltage of the d...

Abstract

The invention discloses a detector drive mechanism in a petroleum well. The detector drive mechanism in the petroleum well comprises a drive motor and a speed reducer. Gear sets and an output shaft are arranged in the speed reducer. Inner teeth are arranged on the inner surface of a shell of the speed reducer. All the gear sets except the last gear set are each provided with a sun gear. Each gear set comprises a gear disc, one face of each gear disc is provided with three planet gears, the center of the other face of each gear disc is fixedly provided with the corresponding sun gear, on the one hand, every three planet gears are meshed with the inner teeth, on the other hand, every three planet gears are meshed with the corresponding sun gear of the previous level, and therefore the gears are connected level by level. The drive motor supplies original power to a high-temperature drive mechanism, rotation of the drive motor is transmitted to the output shaft through the speed reducer, and meanwhile the rotation moment is increased. Heat exchange conducted between the external environment and the drive mechanism is stopped through a heat insulation layer and it is guaranteed that the detector drive mechanism works stably at the high temperature. The application temperature of the drive mechanism ranges from -40 DEG C to 200 DEG C and the drive mechanism can work stably at the high temperature of 150 DEG C for over 15 minutes.

Description

technical field [0001] The invention relates to a geophone, in particular to a geophone driving mechanism in an oil well under a high-temperature environment. Background technique [0002] Due to the limitation of the working environment, the drive mechanism of the geophone in the oil well is small in size, large in transmission ratio, large in transmission torque, and has limitations in high temperature resistance. The practical application shows that the driving mechanism is difficult to work stably under the condition of 150°C, which affects the well operation under the high temperature condition. The failure of the driving mechanism occurs frequently under the condition of 150°C, and the design of the driving mechanism under high temperature environment is one of the key technologies of geophones in oil wells. However, due to the unreasonable structure of the existing detector drive mechanism, the contradiction between the volume and the large transmission ratio is caus...
