Abstract
An oil pipe-coupling detector comprises an upper flange (1), a sensor (2), a vehicle-carrying power (3), an alarm (4), a switch (5), a socket (6), a lower flange (7) and a through pipe (8). As the sensor (2) is equipped at the through-pipe connecting the upper flange and the lower flange, and connected with the switch, the vehicle-carrying power and the alarm via the socket. A coupling position can be forecast when a pipe column is tripped, so two annular well plugging devices can work alternatively to prevent an annular rubber core from being torn by a coupling step, extend the usable life of the rubber core and reduce the cost and labor intensity. Thus, the detector is safer and favorable for the environment. The utility model is provided with advantages of being simple in the structure, easy in operation and control, direct in display and doubly secure in the alarm, and is applied on the pressure maintenance site of a high-pressure oil, gas and injection well. The detector reduces the cost and is quite fit for wide application.
Description
The utility model relates to the subsurface tool that uses on a kind of oilfield, particularly a kind of tubing joint detection instrument.
The annular blowout preventer that uses in the high-pressure oil gas well maintenance Operating Pressure device belongs to hydraulic control equipment, high-pressure and hydraulic oil enters annular blowout preventer by oil pipeline, hydraulic oil pushes the glue core in the annular blowout preventer, and the glue core deforms and realizes the effect of packing annular space or shut-in well.But the glue core in the annular blowout preventer exists serviceable life short, easily torn by the tubing joint step, cause scrapping of itself, and its cost is higher, adopt two annular blowout preventer alternations up and down to contact with the direct of annular rubber core to avoid tubing joint for this reason, but owing to do not determine the position that box cupling arrives, and can not be completed.
The purpose of this utility model is to provide a kind of collar finder, and it can notify the operating personnel by sound and light alarm when box cupling arrives detector, and this moment, the operating personnel can realize the operation that above-mentioned two annulars are fallen back and forth after knowing the position that box cupling arrives.
The purpose of this utility model is to realize like this, it is made up of upper flange (1), sensor (2), vehicle power (3), alarm (4), switch (5), socket (6), lower flange (7), siphunculus (8), on upper flange (1) and siphunculus (8) that lower flange (7) is connected sensor (2) is housed, sensor (2) is connected with switch (5), vehicle power (3) and alarm (4) by socket (6) respectively.
After the energising, main coil in the sensor will form a stable saturation magnetic field, and will be when this utility model device is passed through in tubing joint, bigger than oil pipe area by the area of hand box cupling, the magnetic flux that this moment, sensor produced changes, and the secondary coil induction electromotive force in the sensor also changes.We are converted to electric signal with this variable quantity, and this signal is amplified, handles, and export with the form of sound and light alarm at last.Hear alerting signal, operator can be operated control and make two annular blowout preventer alternations up and down, thereby greatly reduces annular consumption.
The utility model is owing to adopted on upper flange and siphunculus that lower flange is connected sensor has been housed, and sensor is connected with switch, vehicle power and alarm by socket respectively.When playing lower tubular column, can directly forecast the position of box cupling, thereby make two annular blowout preventer alternations, make annular rubber core can avoid tearing of box cupling step, prolong the serviceable life of glue core, reduce cost and working strength of workers, safe and environmentally friendly.This utility model has simple in structure, operation, control easily, advantages such as intuitive display, warning dual fail-safe.After being applied to high-pressure oil gas well allowing pressurized maintenance operation field, reduced cost consumption, be well suited for applying.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in the figure, the utility model is made up of upper flange 1, sensor 2, vehicle power 3, alarm 4, switch 5, socket 6, lower flange 7, siphunculus 8, on upper flange 1 and siphunculus 8 that lower flange 7 is connected sensor 2. sensors 2 is housed and is connected with switch 5, vehicle power 3 and alarm 4 by socket 6 respectively.After the energising, the main coil in the sensor (2) will form a stable saturation magnetic field.When this utility model device was passed through in tubing joint, because the area of box cupling is bigger than oil pipe area, the magnetic flux that this moment, sensor produced changed, and the secondary coil induction electromotive force in the sensor also changes.We are converted to electric signal with this variable quantity, and this signal is amplified, handles, and export with the form of sound and light alarm at last.Hear alerting signal, operator can be operated control and make two annular blowout preventer alternations up and down, thereby greatly reduces annular consumption.
The material of siphunculus necessarily requires should be the high pressure resistant material of the magnetic line of force shielding that does not make main coil.
After the outage, this device only plays an airtight channeling in high-pressure oil gas well maintenance Operating Pressure device, do not influence job execution.
Claims (2)
1, a kind of tubing joint detection instrument, it is made up of upper flange (1), sensor (2), vehicle power (3), alarm (4), switch (5), socket (6), lower flange (7), siphunculus (8), it is characterized in that: on upper flange (1) and siphunculus (8) that lower flange (7) is connected sensor (2) is housed, sensor (2) is connected with switch (5), vehicle power (3) and alarm (4) by socket (6) respectively.
