Compared with prior art, the utility model has the advantage of, use the hydrostatic bridging plug of realizing to set according to bridging plug setting tool of the present utility model and bridging plug seating and sealing unit, avoid the priming systems such as gunpowder, having saved pitching suppresses and sets, reduce construction organization difficulty and construction cost, be conducive to applying of bridging plug multistage subsection fracturing technique.
Brief description of the drawings
To be described in more detail the utility model based on embodiment and with reference to accompanying drawing hereinafter.Wherein:
Fig. 1 is according to the schematic diagram of bridging plug seating and sealing unit of the present utility model;
Fig. 2 is the zoomed-in view of the A part in Fig. 1.
In the accompanying drawings, identical parts use identical Reference numeral.Accompanying drawing is not according to actual scale.
Detailed description of the invention
The utility model is described in further detail will to engage accompanying drawing below.
Fig. 1 has shown according to the schematic diagram of bridging plug seating and sealing unit 10 of the present utility model.Bridging plug seating and sealing unit 10 comprises two bridging plug setting tools 20 and 40 that series connection arranges.The structure of these two bridging plug setting tools is substantially identical, is only described as an example of the bridging plug setting tool 20 of upstream example below.
Bridging plug setting tool 20 comprises the central tube 21 being fixedly installed, and is socketed in the piston cylinder 22 outside central tube 21.Be provided with radially outward the ring-type junction piece 23 protruding at the downstream end of central tube 21,22 of piston cylinders are under the guiding of ring-type junction piece 23 and can arrange slidably.For fear of piston cylinder 22 central tube 21 that slips away, be provided with the locating ring protruding radially inwardly 24 coordinating with ring-type junction piece 23 in the downstream part of piston cylinder 22.In confined state, the downstream of locating ring 24 in ring-type junction piece 23, only can move along central tube 21 piston cylinder 22 towards downstream.
In the upstream portion in the gap between central tube 21 and piston cylinder 22, be provided with piston 25, piston 25 is connected with central tube 21 with piston cylinder 22 by shear pin 26 simultaneously.For piston 25 is moved towards downstream with respect to central tube 21 together with piston cylinder 22, the diameter that shear pin 26 is made as to its part being connected with central tube 21 is less than the diameter of its part being connected with piston cylinder 22, can realization only cuts off part that the connected part of shear pin 26 central tube 21 ensures that shear pin 26 is connected with piston cylinder 22 and realizes this object for intact by controlling hydraulic coupling.In addition, in original state, also piston 25 is set to keep at a certain distance away with ring-type junction piece 23, makes piston 25 there is space.In a specific embodiment, on the contact surface of piston 25 and piston cylinder 22, be provided with the first seal, on the face that is provided with the second seal on the face contacting with central tube 21 at piston 25, contact with piston cylinder 22 at ring-type junction piece 23, be provided with the 3rd seal, central tube 21, piston cylinder 22 and piston 25 surround the cavity 30 of sealing thus.The existence of cavity 30, can avoid the sliding path of piston 25 contaminated or damaged, thereby ensures that piston 25 can smooth sliding.
In order further to ensure piston 25 and piston cylinder 22 energy smooth sliding, bridging plug setting tool 20 also comprises the adjustable ring 31 being fixedly connected with central tube 21, for example, be threaded connection.The upstream portion slidingtype of piston cylinder 22 is between adjustable ring 31 and central tube 21.As shown in Figure 1, be fixedly installed top connection 32 in the upstream of central tube 21, adjustable ring 31 is configured to cylindric and its upstream portion and top connection 32 is threaded togather and downstream part is vacant state, and the upstream portion of piston cylinder 22 is between the unsettled downstream part of adjustable ring 31 and central tube 21.In the motion process of piston cylinder 22, piston cylinder 22 can be subject to the constraint of adjustable ring 31 and central tube 21, and only can in axial direction, move, thereby can ensure stable the carrying out that bridging plug sets.
In a specific embodiment, be provided with the step part 33 of reduced diameter in the upstream portion of piston cylinder 22, it extends to the end, upstream of piston cylinder 22 and between adjustable ring 31 and central tube 21, as shown in Figure 2.In addition, the axial length of cavity 30 is less than the axial length of step part 33, even if piston 25 slides into final position like this, step part 33(, piston cylinder 22) be still subject to the constraint of adjustable ring 31, thereby can ensure the stable motion of piston 25 and piston cylinder 22.That piston cylinder 22 has gap 35 with the bonding part of adjustable ring 31, as shown in Figure 2 with should also be noted that.Liquid can apply the active force towards downstream to piston 25 by this gap 35, thereby driven plunger 25 and piston cylinder 22 move towards downstream.
The bridging plug setting tool 40 in downstream is substantially identical with the structure of the bridging plug setting tool 20 of upstream, for simplicity, only describes both differences here.As shown in Figure 1, the piston 45 of bridging plug setting tool 40 contacts with the downstream end of the piston cylinder 22 of upstream bridging plug setting tool 20, it is applied to the active force towards downstream.Be fixedly connected with lower contact 43 with the inner side of the downstream end of the central tube 21 ' matching of bridging plug setting tool 40, lower contact 43 is fixedly connected with bridging plug 50 again.The downstream part of the piston cylinder 42 of bridging plug setting tool 40 also contacts to realize setting of bridging plug 50 with bridging plug 50.
Although the utility model is described with reference to preferred embodiment, in the situation that not departing from scope of the present utility model, can carries out various improvement and can replace parts wherein with equivalent it.Especially, only otherwise have structural hazard, every technical characterictic of mentioning in each embodiment all can combine in any way.The utility model is not limited to disclosed specific embodiment in literary composition, but comprises all technical schemes in the scope that falls into claim.
