Composite well vibration detection device

Abstract

The invention relates to an oscillation detection apparatus in a complex well. The oscillation detection apparatus is composed of a bearing hook, a housing, a detector unit, a self-compensation eccenteringailll unit, a hydrophone unit and a cable group. The housing includes an upper cylinder body, a middle cylinder body and a lower cylinder body. The detector unit includes a movement fixing body, a cable fixing block, etc. The movement fixing body and the cable fixing block are respectively in secured packaging inside the upper cylinder body via bolts and O-shaped seal rings. The self-compensation eccenteringailll unit is mounted inside the middle cylinder body and includes a motor, a screw rod, a sliding nut, an upper rocking arm, a lower rocking arm and a supporting rod, wherein the screw rod has a lower portion connected to an output shaft of the motor and has a upper portion connected to the sliding nut. The sliding nut hinges the supporting rod via the upper rocking arm and the lower rocking arm. The supporting rod extends out of the middle cylinder body is strutted on the well wall. The hydrophone unit is mounted inside the lower cylinder body. The oscillation detection apparatus has a reasonable composition, and has self-compensation eccenteringailll function. The oscillation detection apparatus not only can detect vibration signals, but can also detect water pressure variation signals, and is characterized by reliable sealing and easy operations, such as assembling, maintenance, and interchanging.
