Abstract
A screw pump blowout prevention supporting slips anchoring tool comprises a blowout prevention upper connector, a blowout prevention center pipe, a blowout prevention lower connector, a center pipe, a tubing anchor and a centralizer and is characterized in that the upper end of the blowout prevention center pipe is inserted in an inner hole in the lower end of the blowout prevention upper connector and is connected with the blowout prevention upper connector through a release pin, two symmetrical key grooves are formed in the upper portion of the blowout prevention center pipe, two symmetrical guiding pins are arranged at the lower end of the blowout prevention upper connector, and the inner end of each guiding pin is located in the corresponding key groove; a plug is in threaded connection with the upper end of the blowout prevention center pipe, taper pipe external threads at the lower end of the blowout prevention center pipe are connected with taper pipe internal threads at the upper end of the blowout prevention lower connector, and the lower end of the blowout prevention lower connector is connected with the center pipe. The tool can seal and isolate an oil flow channel so as to achieve blowout prevention, effectively prevent failed oil waste and environment pollution, and protect the ecological environment. The tool is simple in structure, capable of saving equipment investment, convenient to use and high in safety performance. Repeated oil extraction and workover treatment can be achieved in the slips setting state.
Description
Technical field
The invention belongs to a kind of oil well production equipment, particularly a kind of screw pump blowout prevention supporting slip anchor tool.
Background technology
When producing well in oil field carries out workover treatment, the situation that downhole crude lands can be there is, cause the waste of earth's surface pollution and the energy, in the past in order to prevent crude oil to land, need to configure preventer in addition, so not only add the investment of equipment, make the fitter's work of producing well complicated simultaneously.
Summary of the invention
The object of this invention is to provide a kind of screw pump blowout prevention supporting slip anchor tool, there is the function of packing oil flow channel, thus realize blowout prevention, effectively prevent landing oil from wasting and environment pollution, preserve the ecological environment.Owing to not needing separately to join preventer, save equipment investment, simplify and install preparation, easy to use, quick, simple and reasonable, reliability, safety are good.
Technical scheme of the present invention is: comprise blowout prevention top connection, blowout prevention central tube, blowout prevention lower contact, central tube, tubing anchor and centralizer, it is characterized in that: blowout prevention central tube upper end is inserted in the endoporus of blowout prevention top connection lower end, and connected by release pin, blowout prevention central tube upper periphery face is processed with two symmetrical keyways, blowout prevention top connection lower end is provided with two symmetrical guide pins, the inner of guide pin is positioned at keyway, blowout prevention central tube threaded upper ends connects shutoff, shutoff is provided with step and male cone (strobilus masculinus), the inner conical surface of this male cone (strobilus masculinus) sealing contact blowout prevention top connection endoporus, blowout prevention central tube lower end Taper Pipe external screw thread is connected with the Taper Pipe internal thread of blowout prevention lower contact upper end, the Taper Pipe external screw thread of blowout prevention lower contact lower end is connected with the Taper Pipe internal thread of central tube.
Good effect of the present invention: the function 1, with packing oil flow channel, thus realize blowout prevention, effectively prevent landing oil from wasting and environment pollution, achieve environmental protection operation, preserve the ecological environment.2, owing to not needing separately to join preventer, part is few, and this tool construction is simple, saves equipment investment, simplifies and installs preparation.3 is easy to use, quick, and sealing is reliable, and safety is good.4, use the gravity of supporting slip to sit card to be combined with the action principle of the spraying-preventing system of this instrument, under the state of sitting card, can complete and repeat to recover the oil and workover treatment.

Detailed description of the invention
See Fig. 1-6, concrete structure of the present invention is as follows:
Spraying-preventing system of the present invention is made up of blowout prevention top connection 1, shutoff 2, release pin 3, guide pin 4, blowout prevention central tube 5.Concrete structure is as follows: there is Taper Pipe internal thread blowout prevention top connection 1 upper end, for connecting screw rod pump Taper Pipe external screw thread.Blowout prevention central tube 5 upper end is inserted in the endoporus of blowout prevention top connection 1 lower end, and connected by release pin 3, blowout prevention central tube 5 upper periphery face is processed with two symmetrical keyway P, blowout prevention top connection 1 lower end is provided with two symmetrical guide pins 4, the inner of guide pin 4 is positioned at keyway P, blowout prevention central tube 5 threaded upper ends connects shutoff 2, shutoff 2 is provided with step and male cone (strobilus masculinus) C, this male cone (strobilus masculinus) C seals the inner conical surface of contact blowout prevention top connection 1 endoporus, blowout prevention central tube 5 lower end Taper Pipe external screw thread is connected with the internal thread of blowout prevention lower contact 6 upper end, the internal thread of blowout prevention lower contact 6 lower end is connected with the external screw thread of central tube 7.By prior art, tubing anchor 8, centralizer 9 suit are connected on the outer wall of central tube 7.
Operating principle:
By blowout prevention top connection 1 upper end by internal thread connecting screw rod pump Taper Pipe external screw thread, screw pump upper end is connected with flow string, and central tube 7 lower end is threaded connection the instruments such as tail pipe.
1. go into the well: this instrument is connected to screw pump bottom, slowly G.I.H, the slips of tubing anchor is in non-open configuration.
2. sit card: under this instrument after projected depth, start to sit card.Watch out for slowly and spray joint 1, the rail groove Q of centralizer 9 centrally pipe 7 moves, and makes the slips of tubing anchor 8 open grappling.
3. blowout prevention passage is opened: because the slips of tubing anchor 8 opens grappling, blowout prevention central tube 5 is fixed, blowout prevention top connection 1 is made to move down under the Action of Gravity Field of the flow string of screw pump upper end, release pin 3 is cut off, blowout prevention top connection 1 moves downward until contact with the step of blowout prevention central tube 5 by guide pin 4 along keyway P, stops sliding, and blowout prevention passage R opens, crude oil enters in oil pipe pump barrel, at this moment can normal oil producing operation.
4. blowout prevention pathway closure: when workover treatment, due to the slips anchoring of tubing anchor 8, above watches out for and sprays joint 1, and blowout prevention top connection 1 moves upward until contact with the male cone (strobilus masculinus) C of shutoff 2 by guide pin 4 along keyway P, and blowout prevention passage R closes.
5. unfreezing: if think oil producing operation again, continuation is carried, blowout prevention top connection 1, the rail groove Q of centralizer 9 centrally pipe 7 moves, and makes the slips of tubing anchor 8 be contracted to home position, completes unfreezing operation.
