Abstract

The invention relates to a protective device which gives alarm automatically when an anti-skid drill meets obstruction or blockage during the work of drilling a well or repairing a well; the technical proposal adopted by the invention is that: the protective device comprises a driller operating platform, a hydraulic sensor, a detector, a PLC circuit and an electromagnetic valve; the hydraulic sensor converts a hydraulic signal of the drawing force of a deadline into an electric signal which is sent to the PLC circuit; the detector detects the height of the position of a detecting car so as to send out a control signal to the PLC circuit; the two signals sent to the PLC circuit are calculated by the PLC, thereby comparing the drawing force of the deadline and the deadweight of a drilling tool, recognizing inward drilling, initial drilling and downward drilling, controlling whether the electromagnetic valve is braked and preventing the skid of the drill or giving an alarm when meeting the obstruction or blockage. The protective device of the invention has the advantages that: when the drilling tool meets the obstruction when starting to drill, an alarming signal is sent out in time so as to remind drivers to pay attention to taking measures to prevent the happening of the accidents; the protective device can cooperate with a weight indicator to realize safe and quick production and performs dual functions of reminding and compulsory brake; when drilling inward, the protective device can assist in preventing the skid of the drill from happening, thus being beneficial to the protection of the drill and the drilling tool.

Description

Slide-preventing, the card automatic alarm protecting is hampered
One, technical field:
The present invention relates to a kind of drilling well, workover treatment instrument, particularly relate to a kind of slide-preventing, the card automatic alarm protecting is hampered.
Two, background technology:
Oil drilling is a hidden underground construction, has a large amount of ambiguities, randomness and uncertain problem.In drilling well work, creeping into, pulling out of hole, boring down is one of key link of drilling well work, creep into and just be to use certain rock crushing tool, utilize the rotation of device drives rock crushing tool, operating personnel according to certain pressure uniformly to rock crushing tool exert pressure (the pressure of the drill), realize constantly broken bottom rock, deepen the process of well; And rise, bore down is to need many reasons such as variation, formation factor owing to plant issue, drill bit mode of occupation, drilling tool structure, just needs, bores down; When creeping into, operating personnel's level is low or energy is concentrated, just the drilling string not well braked problem might take place, and bit life is reduced, even drill bit is scrapped, and well is beaten tiltedly.Rise, in the going down process; may there be reasons such as pressure reduction, sand setting or sand bridge, borehole collapse, bit balling, hole shrinkage, keyway owing to the down-hole; run into the phenomenon that is hampered, meets card through regular meeting; if chance card, the phenomenon that is hampered can not in time be found and handle at this moment; will make complicated down-hole situation complicated more, even can develop into accident.
Creeping into the prevention of slide-preventing, trip-out chance card, slacking off and handling at present mainly is to control from people's operating aspect, as formulate rational rules and regulations, the aspects such as technical level that promote the operator are come accomplished, yet, since sometimes people's energy do not concentrate or the process that makes a trip in, unexpected be hampered, meet card, if in time do not take measures and to have an accident at this moment.
Three, summary of the invention:
Purpose of the present invention is exactly the above-mentioned defective that exists at prior art; a kind of slide-preventing is provided, the card automatic alarm protecting is hampered; make equipment change into prompting initiatively and control situation initiatively, realize preventing accident, reach the purpose of safety in production from passive behavior in service.
Its technical scheme is: comprise driller's operating platform, hydrostatic sensor, probe, PLC treatment circuit and electromagnetic valve, the checkmate hydraulic pressure signal of rope tension of described hydrostatic sensor changes the signal of telecommunication into and is sent to the PLC treatment circuit; Described probe is surveyed tourist bus position height, gives the PLC treatment circuit to spread out of control signal; Two kinds of signals are transferred to the PLC treatment circuit, by the PLC sequential operation, and relatively dead line pulling force and drilling tool deadweight, identification is crept into, is pulled out of hole automatically, whether brill, and then control electromagnetic valve down brake, and prevents drilling string not well braked or the card that is hampered gives the alarm.
Above-mentioned driller's operating platform is provided with suspending weight controller, controlled quentity controlled variable setting apparatus, alarm lamp or sound indication and gauge tap is set; Described suspending weight is provided with controller correction suspending weight value is set, and described controlled quentity controlled variable setting apparatus is set three kinds of operating modes, sets two values for every kind, reports to the police second brake when first reaches; Described gauge tap is that the electromagnetic valve anti-collision overhead traveling crane gas circuit that resets is closed the winch operate as normal when closing.
Above-mentioned PLC treatment circuit comprises: sensor (A), to zero, alarm setting down, trip-out, power line, sensor (B), cancellation protection, go up the alarm setting, bore down, brake indication, early warning indication, indication at zero point, the alert output of tabloid, upper limit indication, lower limit indication, clutch for clutch control and big warning export; In drilling process, set normal the pressure of the drill, on normal the pressure of the drill basis, set an added value, arrive added value the indicator lamp at driller's operating desk place is given the alarm, the prompter takes measures, and when forcing brake greater than the added value system, prevents drilling string not well braked; Trip-out greater than, bore when setting added value down, the indicator lamp at driller's operating desk place is given the alarm, surpass when setting maximum value or minimum value meeting card or be hampered, force brake to prevent that complex situations from worsening.
The invention has the beneficial effects as follows: (1), when the drilling tool that makes a trip is hampered, in time send alarm signal, remind the driller to note in time taking measures to avoid the generation of accident; (2), match with weight indicator and to realize safely and fast production, the dual function that plays timely prompting and force brake; (3), when creeping into, can assist the generation that prevents drilling string not well braked, help protecting drill bit, drilling tool.
