By technique scheme, the internal diameter of described central tube is not less than 62 mm, and central tube is no longer than 550mm.
The utility model can be connected with special setting tool, and with its G.I.H.After bridging plug sets, take out setting tool, and drop into solvable de-plugging ball and can realize pit shaft temporary blocking, for well fracturing creates conditions.After pressure break, stifled ball gets final product automatic dissolving without the need to boring mill, because latus rectum in this bridging plug is large, can not affect later stage production.
Beneficial effect acquired by the utility model is: big orifice press-fracturing bridge plug heatproof, pressure-bearing index are high, dependable performance, and interior latus rectum is large, need not bore plug operation can allow Oil/gas Well transfer production to from measure, may be used for darker horizontal segment to set, operating cost is low, and efficiency is high; Because bridging plug adopts single slip design, length is short, lightweight; And employing is that composite processing forms, when needs bore mill, brill wearing time is fewer than conventional bridging plug, and risk is little; Arranging mutually with central tube by arranging two groups of locking devices, preventing the resilience of packing element assembly, further increasing the sealing performance of this device.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of big orifice press-fracturing bridge plug that the present embodiment provides, it comprises central tube 2, packing element assembly, slip assemblies, lower contact 12, described packing element assembly, slip assemblies, lower contact is sleeved on central tube 2 from top to bottom successively, inner conical surface is provided with and solvable stifled ball matches in the upper end of central tube, slip assemblies is fixed on central tube 2 by shop bolt 10, slip assemblies is provided with the second locking device and central tube phase configuration, lower contact is provided with the first locking device and central tube phase configuration, lower contact 12 is fixed on central tube 2 by starting pin 14.
In the present embodiment, described packing element assembly comprise set gradually upper throw-out collar 3, protection bowl 4, end packing element 5, middle packing element 6, lower protection bowl, lower throw-out collar 7; Described slip assemblies comprises cone 8, slips 9, and cone 8 is fixed on central tube 2 by shop bolt 10, hollow out in slips.Wherein, the periphery of upper throw-out collar 3 and lower throw-out collar 7 is provided with annular groove, when facilitating packing element to compress, central tube is provided with lock tooth, first locking device comprises the first snap be fixed on by pin 13 in lower contact 14, and this first snap configures for being meshed with the lock tooth on central tube; Second locking device is included in the second snap 9 fixing by pin in cone 8, and this second snap 9 configures for being meshed with the lock tooth on central tube;
In the present embodiment, at the lower end edge circumference interval of central tube 2, multiple arc column 15 is set, groove is formed between adjacent arc column, lower contact is sleeved on arc column 15 and is also fixed on arc column 15 by starting pin 14, the lower end respective slot of lower contact is provided with spacing radial boss 16, the step 17 formed by groove, for keeping out spacing radial boss 16, limits the displacement of the relative centre pipe of lower contact.
In the present embodiment, described central tube, packing element assembly, slip assemblies, lower contact all select composite material to be made, such as adopt glass fiber reinforced composite resin material or fibre reinforced composite resin material etc., wherein, the internal diameter of described central tube is not less than 62mm, and central tube is no longer than 550mm.
In the present embodiment, upper throw-out collar 3 and lower throw-out collar 7 are provided with groove, so that it is provided enough compression strokes when compressing.
Big orifice press-fracturing bridge plug of the present utility model is connected with special setting tool, by cable G.I.H desired location.Start setting tool after cable energising, the pushing cylinder of setting tool acts on the upper surface of central tube 2, and the pull bar of setting tool drives lower contact 12 to move, and relative displacement occurs for lower contact 12 and central tube 2, cuts off and starts pin 14.Under the lasting setting force that setting tool produces, slips 11 moves, and promotes the lower throw-out collar 7 of cone 8 extruding, lower protection bowl, middle packing element 6, end packing element 5, upper protection bowl 4, upper throw-out collar 3.Extruded packing element component strain, the annular space between center seal pipe 2 and sleeve pipe, extruded upper throw-out collar 3, upper protection bowl 4 and lower protection bowl, lower throw-out collar 7 are out of shape, and protection packing element can bear high pressure.Meanwhile, under the active force of lower contact, the shop bolt 10 in cone 8 is cut off, and moves to central tube upper end, and extruded slips 11 breaks under the support of cone 8, is anchored on internal surface of sleeve pipe; Simultaneously; the first snap in lower contact 10 engages with the lock tooth of central tube 2 outer wall; the second snap in cone engages with the lock tooth on central tube; prevent throw-out collar 3, protection bowl 4, end packing element 5, middle packing element 6, lower protection bowl, lower throw-out collar 7, cone 8, slips 9 resilience and cause seal failure, make packing element assembly be in sealing state.Afterwards, setting tool improves setting force further, and the pull bar of setting tool discharges lower contact 12, realizes giving up (namely setting tool is separated with big orifice press-fracturing bridge plug).Complete bridging plug set and give up, take out setting tool, and drop into after solvable de-plugging ball 1 realizes pit shaft temporary blocking and can implement pressing crack construction.After pressure break, solvable de-plugging ball 1 without the need to bore mill can with liquid generation chemical reaction in pit shaft, automatic dissolving.Because latus rectum in this bridging plug is large, later stage production can not be affected.Produce " current limliting " to production passage almost can ignore.In addition, this bridging plug adopts composite processing, as the later stage needs to bore mill bridging plug, bores mill efficiency also higher than conventional composite bridge plug.
