Hydraulic coupling alarm device

Abstract

A hydraulic type coupling alarm device comprises a hydraulic device, a hydraulic pipeline, a hydraulic system, a transmission device, a compression device, an alarm device and connection components. The hydraulic type coupling alarm device overcomes the defects of fraudulent alarm and false alarm of an existing coupling alarm, and is arranged and connected at the lower portion of an annular well sealing device. When a coupling passes, sound-light alarm signals are given out, an operator opens the annular well sealing device, the coupling is prevented from cutting a rubber core, the service life of the rubber core is prolonged, and the cost consumption is lowered. The hydraulic type coupling alarm device is stable in performance and is accurate and effective in alarming.

Description

technical field [0001] The invention relates to a collar alarm device used on a pressure operation device of a high-pressure oil, gas and water well, in particular to a hydraulic coupling alarm device. Background technique [0002] At present, the annular seal used in the snubbing operation device of high-pressure oil, gas and water well belongs to the hydraulic control equipment, which is used to seal the annular space between the tubing and the casing. The internal rubber core is very easy to cause damage to the rubber core, resulting in an increase in cost; while the existing collar alarm consists of a housing, rollers, roller frames, racks, springs, spring seat screw nuts, lead screws, hand Wheel, distance sensor, pull rod, turntable, and gear shaft are connected to each other; when the coupling of the pipe string passes through its main diameter, the protruding part of the pipe string squeezes the roller, so that the roller and the roller frame passively move to both en...

Problems solved by technology

[0002] At present, the annular seal used in the snubbing operation device of high-pressure oil, gas and water well belongs to the hydraulic control equipment, which is used to seal the annular space between the tubing and the casing. The internal rubber core is very easy to cause damage to the rubber core, resulting in an increase in cost; while the existing collar alarm consists of a housing, rollers, roller frames, racks, springs, spring seat screw nuts, lead screws, hand Wheel, distance sensor, pull rod, turntable, and gear shaft are connected to each other; when the coupling of the pipe string passes through its main diameter, the protruding part of the pipe string squeezes the roller, so that the roller and the roller frame passively move to both ends. The gear rack on the roller frame drives the gear shaft meshed with it to rotate, and the induction wheels at the ends of the gear shafts at both ends rotate toward the center of the wellhead in opposite directions. The joint part has reached the center position of the collar alarm; since this collar alarm adopts a spring structure, the stability of the spring structure itself is poor, and vibrations often occur, and when the oil pipe is lifted and lowered, the oil pipe itself often has swing, and the high pressure environment and other complex conditions in the well will also affect it, so false alarms and false alarms often occur, and the alarm cannot be effectively and accurately
