Fig. 2 is that Figure 1A A is to sectional drawing;
Fig. 3 is the section of structure of scraper.
The specific embodiment
With reference to Fig. 1-Fig. 3, a kind of drilling well is with multi-functional pneumatic slips, comprise supporting disk 1, connecting rod 2, slips body 3, actuating cylinder 4, slip spider 5, scraper 6, control cylinder 9, lock bolt 7 and air distribution connector 8, two slip spiders 5 connect in aggregates by bearing pin, slips body 3 places in the slip spider 5 and by connecting rod 2 and supporting disk 1 and is hinged, and slips body 3 is made as 4 or 6 (among the figure being 4).Scraper 6 is arranged on slip spider 5 lower ends; Actuating cylinder 4 and control cylinder 9 all are arranged on the inside of slip spider 5, and the piston rod of actuating cylinder 4 is fixedlyed connected with supporting disk 1 by bolt, and control cylinder 9 tops are provided with lock bolt 7, and its piston rod is not connected with supporting disk 1; The lower end air inlet port of actuating cylinder 4 and control cylinder 9 all is connected with air distribution connector 8 by inlet channel 11, the gas outlet, upper end of actuating cylinder 4 is connected with air distribution connector by outlet passageway 12, and the gas outlet, upper end of control cylinder 9 is connected by the annular gas passage 13 in insufflation channel 10 and the scraper 6.Actuating cylinder 4 is made as 4, and is evenly distributed on the slips body in one week, and its lower end air inlet port is interconnected, and the gas outlet, upper end is interconnected.Described scraper 6 is trumpet-shaped circular ring for centre bore, and the interior bottom of this structure is provided with annular gas passage 13, and its top cylindrical is provided with the spill annular groove, and described annular gas passage 13 inboards are provided with fumarole 14.The fumarole 14 of annular gas passage 13 inboards is made as 4-12 on the described scraper 6.
During the trip-out operation, after driller buckles well elevator, before promoting drill string, the driller handles pneumatic operated valve, make gas enter into the lower end air inlet port of actuating cylinder 4 and the lower end air inlet port of control cylinder 9 by inlet channel 11 through air distribution connector 8, carry drill string again, the piston rod of actuating cylinder 4 is up, promoting supporting disk 1 rises, it is up and outwards open along slip spider 5 conical surfaces that supporting disk 1 pulling connecting rod 2 drives slips bodies 3, the round opening of four slips body 3 formation increases to maximum gradually, abdicates the drill string passage, allows drill string freely to pass through from the slips center.In this course, the piston rod of the piston rod of control cylinder 9 and actuating cylinder 4 rises synchronously, rise to gradually when the highest, the lower end air inlet port of control cylinder 9 and gas outlet, control cylinder 4 upper end are connected, gas promptly enters annular gas passage 13 in the scraper 6 by insufflation channel 10, blow drill string by the fumarole 14 that is provided with on the scraper 6 along oblique direction down, the mud that adheres on the drill string is blown into well head; Otherwise, when sitting card, driller's reversible control pneumatic operated valve makes gas enter the upper end air inlet port of actuating cylinder 4 through air distribution connector 8 outlet passageways 12, the piston rod of actuating cylinder 4 is descending, pulling supporting disk 1 descends, and it is descending along slip spider 5 conical surfaces to drive slips body 3 through connecting rod 2, simultaneously, the piston rod of control cylinder 9 descends under the pressure of deadweight and supporting disk 1, the circular open of four slips body 3 formation reduces gradually, drill string is passed between two parties, till drill string is blocked in obvolvent.The another one effect of scraper 6 is, when drill string deflection well head, avoids drill string directly wear and tear slip spider 5 and slips body 3, the slip insert on the slips body that prevents to collide with.
Tripping operation: with lock bolt 7 piston rod of control cylinder 9 is locked at the bottom, gas promptly capable of blocking is by control cylinder 9, thereby disconnects scraper 6 sources of the gas, and control cylinder 9 and scraper 6 are not worked.The remaining part operating principle is identical with the trip-out operation.
The utility model adopts complete built-in cylinder and integrated gas circuit structure, is applicable to the Rotary table for drilling machine of any kind, is applicable to tubing strings such as holding drilling rod, drill collar, sleeve pipe, and scraper is replaceable accessory.
