Dual-purpose product (water) device of joining of oil-water well, its blanking plug comprises fishing rod 33, stage clip 32, gland 31, supporting base 38, cam 34, torsion spring 36, fishing rod 33 is worn stage clip 32 and is connected with gland 31 and with supporting base 38, cam 34 usefulness axle 35 and torsion spring 36 are positioned on the supporting base 38, and there is sealing ring 37 to seal, supporting base 38 bottoms are connected with seal section 313, and sealing ring 312 is equipped with in seal section 313 outsides.The top of blanking plug seal section 313 has the axial pass trough that is communicated with the center, the bottom also has the axial pass trough that is communicated with the center, sealing plate 39, profit mouth 310, lining 311, sealing ring 314 are housed in the bottom of blanking plug seal section 313 successively, guide head 315 seal with screwed joint sections 313, and lining 311 and sealing ring 314 compressed.The lining 311 of blanking plug is axially having elongated slot, is used to protect seal section injury-free.The oil of blanking plug, water nozzle 310 variable different-diameters are controlled the injection rate and the production fluid amount of each interval.
Dual-purpose product (water) device of joining of oil-water well, its testing seal section is by top connection 41, sealing ring 42, rubber cup 43, logical liquid 44, spacer ring 45, pressing plate 47, screw 48, locating detent spring 410, spiral shell axle 413, pin 415, torsion spring 416 is formed, stage clip 414 is housed on the lock body 412, the little axle 49 of locating detent 411 usefulness is fixed on the main body 46, when testing seal section is put into seating nipple main body 5 main channel A, locating detent seat 411 open with seating nipple support 8 in the positioning step position consistency time, the two ends of the curve concave surface in two leather cups 43 of testing seal section and the seating nipple main body 5 main channel A contact and seal.
Dual-purpose product (water) device of joining of oil-water well is when the test construction, plug, eccentricity control device, supporting slips, packer (deciding the progression of packer and eccentricity control device according to the production and injection proration scheme of every mouthful of well) are lowered into predetermined interval with oil pipe, in oil pipe, pressurize set packer.After with steel wire for logging tester and testing seal section being descended the eccentricity control device of end level then, carry tester and testing seal section on (switch block 417 of testing seal section go into the well be relayed in the interior space of runner 418), driving runner 418 after switch block 417 is hampered rotates, lock body 412 is descending by the promotion of stage clip 414, and locating detent 411 is opened.Transfer tester and testing seal section, make on the positioning step of open locating detent seat in eccentricity control device seating nipple support 48.The a pair of leather cup of testing seal section just is stuck in three sections major diameter hole slot places in seating nipple main body 45 main channels at this moment, make and inject can only flow through in the instrument fluid hole of the logical liquid 44 of testing seal section of liquid and return out, after flowing to blanking plug by inclined hole, enter (flow direction of produced liquid in oil well is just for opposite) in the oil reservoir from the outer wall liquid outlet groove of seating nipple main body 5, parameters such as layering liquid measure are measured thus.The rest may be inferred, and from bottom to top instrument is once gone into the well and can be surveyed all layers position in the completion tube, and all be to carry out during each layer ordinary production in test process.Trip out tester and testing seal section at last and finish oil water well test and the allotment of profit mouth, make by the well logging reasonable production.
Dual-purpose product (water) device of joining of oil-water well is recovering the oil, when water blockoff and water filling construction, blanking plug is put into seating nipple 5 inclined to one side hole B, blanking plug cam 34 is positioned at shoulder place in the top among the seating nipple 5 inclined to one side hole B, this moment six roads (three groups) sealing rings 312, inclined to one side hole B endoporus is separated into two parts, the axial pass trough on the top of blanking plug seal section 313 is communicated with oil reservoir by inclined to one side hole B, the axial pass trough that is communicated with the center of blanking plug seal section 313 bottoms is communicated with hole E on the hole B partially, by oil, water nozzle 310, lining 311, oil reservoir is communicated with ground, recover the oil, when water blockoff and water filling operation, as long as more change oil, the diameter of water nozzle 310 just can be controlled the injection rate and the production fluid amount of each interval.
The utlity model has following advantage:
1, owing to changed part-structure and the size of eccentricity control device seating nipple main body inclined to one side hole, blanking plug, Enlarged the scope of application of eccentricity control device. Both can as injection well downhole flow regulator usefulness, can use as production mandrel again.
2, local space increases in the main channel of employing seating nipple main body, removes thereby relative remission is with pressure The speed of instrument, leather cup up and down pressure reduction reduce, and alleviate bump and the wearing and tearing of testing seal section rubber cup, Improve the service life of leather cup and the accuracy of test, avoid the test job failure.
3, the main channel of seating nipple main body and the partially inclined hole in hole have solved the bigger impurity of proportion in the pit shaft Enter the problem of oil reservoir.
4, changed testing seal section and when crossing the inclined to one side hole of seating nipple body passageways, shaft collar shut, The technology of opening again behind the via hole reduces test step and engineering time, reduces personnel's labour intensity, carries High testing time-effectiveness.
5, controller is used for layering water distribution tubing string, owing to have 4 by-pass prots to make the overcurrent passageway bridge, When surveying layered waterflooding quantity, surveying which layer is exactly the zonal flow rate of which layer, does not exist with diminishing method and explains Problem. The error of having avoided water filling fluctuation and multi-layer testing to successively decrease and bring is conducive to the layering injection rate The raising of measuring accuracy.
