Abstract
A tubing coupling detector is characterized in that a contact switch (2) is mounted in a pressure guide sleeve (4), the contact switch (2) is connected with a central spindle (7) through a buffer block (3), the central spindle (7) penetrates through a hydraulic cylinder inner sleeve (5) and a hydraulic cylinder outer sleeve (10), and a rolling wheel (12) is mounted at the stretching-out end of the central spindle (7) through a shaft (13). When the tubing coupling detector is applied to oil-water well operation with pressure, the central spindle (7) and the rolling wheel (12) can be pushed to a well mouth sleeve through hydraulic pressure, when a tubing coupling reaches a well mouth, the tubing coupling can push the contact switch (2) through the rolling wheel (12) and the central spindle (7) to give out signals, the arrival time of the tubing coupling can be judged accurately, and harms caused on blowout preventer rubber tubes are avoided.
Description
Technical field: the utility model relates to a kind of oilfield downhole operation equipment, especially for a kind of tubing coupling probe of oil water well working with pressure.
Background technology: before the utility model, Wellhead packer packing element is injured for solving tubing coupling in each oil field in oil water well working with pressure, generally when box cupling arrives, to adopt upper and lower two and half sealing-ins to derive for mode, but owing to cannot accurately judging box cupling time of advent, still can cause the injury of blowout preventer packing element, to job execution, make troubles.
Summary of the invention: the purpose of this utility model is: for oil water well working with pressure provides a kind of tubing coupling probe, because this device is provided with contact switch, mandrel Ji Roll wheel, when box cupling arrives, meeting Tong Guo Roll wheel and mandrel promote contact switch and send signal, thereby can accurately judge box cupling time of advent, avoid blowout preventer packing element to damage.
The purpose of this utility model realizes by following measures: a kind of tubing coupling probe, comprise equalizing valve, pilot cover, contact switch, fluid cylinder inner sleeve, spring, feather key, piston, fluid cylinder overcoat, and the equalizing valve end of thread connects pilot cover successively, with the fluid cylinder inner sleeve of piston with the fluid cylinder overcoat of feather key, it is characterized in that, in pilot cover, a contact switch with cylindrical buffer stopper is installed, and by its buffer stopper, connect the mandrel of an elongated rod shape, mandrel is through fluid cylinder inner sleeve and fluid cylinder overcoat, its external part has rectangular channel and by axle, one disc-shaped Roll is installed and takes turns, spring is installed between mandrel and fluid cylinder inner sleeve simultaneously and meshes and spacing by the axial groove processed on its outer wall and the feather key in fluid cylinder overcoat.
The utility model is for oil water well working with pressure, can Tong Guo Roll wheel when box cupling arrives well head place and mandrel promote contact switch and send signal, thereby can accurately judge box cupling time of advent, avoid blowout preventer packing element to damage.
Accompanying drawing explanation: Fig. 1 is the structural representation of tubing coupling probe.
Fig. 2 is the working state schematic representation of tubing coupling probe.
The specific embodiment: tubing coupling probe comprises equalizing valve 1, pilot cover 4, contact switch 2, fluid cylinder inner sleeve 5, spring 6, feather key 8, piston 9, fluid cylinder overcoat 10, and equalizing valve 1 end of thread connects pilot cover 4 successively, with the fluid cylinder inner sleeve 5 of piston 9 with the fluid cylinder overcoat 10 of feather key 8; In pilot cover 4, a contact switch 2 with cylindrical buffer stopper 3 is installed, and by the mandrel 7 of its buffer stopper 3 connection one elongated rod shape, mandrel 7 is through fluid cylinder inner sleeve 5 and fluid cylinder overcoat 10, and its external part has rectangular channel and by axle 13, a disc-shaped Roll wheel 12 is installed; Spring 6 is installed between mandrel 7 and fluid cylinder inner sleeve 5 simultaneously and meshes and spacing by the axial groove processed on its outer wall and the feather key in fluid cylinder overcoat 10 8.
Operating principle and the using method of tubing coupling probe are: first with clip 14, fluid cylinder overcoat 10 is arranged on to valve 15 ports of export of well head four-way 16 and opens valve 15 together with this device, by the pressure guide hole on fluid cylinder overcoat 10, pressurize again, make piston 9 promotion fluid cylinder inner sleeve 5 Bing Dai moving mandrels 7 and roller 12 thereof pass valve 15 to the sleeve pipe place of well head four-way 16, and roller 12 is contacted (Fig. 2) with oil pipe 17 outer walls, now just can carry out job execution; In operation, when the box cupling 18 of down-hole arrives, can promote contact switch 2 actions with buffer stopper 3 by roller 12 and mandrel 7, send signal and notify operating operator, thereby can accurately judge 18 times of advent of box cupling, avoid it to blowout preventer packing element, to damage.After box cupling 18 passes through, under the effect of spring 6, mandrel 7 and roller 12 thereof can reset, ready for continuing detection.
