In a preferred embodiment, described top connection is arranged with baffle ring, described baffle ring contact is on described contact wall.
In a preferred embodiment, described top connection has injection channel, and described injection channel is connected with described pipe core.
In a preferred embodiment, multiple O-ring seals is respectively equipped with between described body and described intermediate head, between described intermediate head and described top connection and between described body and described lower sub.
Feature and the advantage of pressure testing device of the present invention are: this pressure testing device is in relevant position appearance damage or when not conforming with testing requirements, only need change corresponding parts, thus can effectively save test material, not need large-scale experiment equipment, and structure is simple, be easy to processing.The intermediate head of this pressure testing device and body can the size of experimentally instrument be changed, and after experiment terminates, test packer or tubing string are removed and can carry out next time and test.In addition, this pressure testing device, when dismantling, is first laid down baffle ring, is then unloaded intermediate head, the packer of test or tubing string can be removed, its convenient disassembly, be easy to change experimental tool finally by unloading top connection.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the cut-open view of pressure testing device of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the invention provides a kind of pressure testing device, it comprises pipe core 1 and body 2, wherein: one end of pipe core 1 is connected with top connection 3; Body 2 is set in outside described pipe core 1, and one end of described body 2 is connected with intermediate head 4, and described intermediate head 4 is socketed in described top connection 3, and the other end of described body 2 is connected with lower sub 5, and the sidewall of described body 2 is connected with multiple liquid inlet joint 21.
Specifically, pipe core 1 is substantially in cylinder barrel shaped, and top connection 3 has stage portion 31, and the threaded one end of pipe core 1 is connected to the inner side of the stage portion 31 of top connection 3.Top connection 3 has injection channel 32, and this injection channel 32 is connected with pipe core 1.
Intermediate head 4 has the socket part 41 and connecting portion 42 that are connected, socket part 41 has the socket tube 411 be connected with connecting portion 42 and the contact wall 412 being connected to socket tube 411 one end, socket tube 411 is set in the outside of the boss portion 31 of top connection 3, and contact wall 412 contact is on the you face of boss portion 31.In the present invention, sheathedly in top connection 3 be connected with baffle ring 6, baffle ring 6 contact is on the contact wall 412 of intermediate head 4, and the benefit of design is like this, top connection 3 and intermediate head 4 are not threaded connection, and can be prevented the movement of top connection 3 by baffle ring 6.
Body 2 is substantially in cylinder barrel shaped, and its one end is threaded in the outside of the connecting portion 42 of intermediate head 4, and the other end inside thread of body 2 is connected with lower sub 5.
When being tested by the sealing property of this pressure testing device to packer, first, be connected with packer by pipe core 1, then, suppressed in packer by the injection channel 32 of top connection 3, the packing element of packer expand and contact on the internal face of body 2, after treating packer setting, by the liquid inlet joint 21 on body 2 to suppress to body 2 inside test packing element anti-in the ability of external pressure.
By this pressure testing device to tubing string bear interior external pressure performance test time, first, be connected with one end of tubing string by pipe core 1, the other end of tubing string sealed up, then, suppressed in tubing string by the injection channel 32 of top connection 3, test string anti-in pressure; In body 2, the critical external compressive resistance getting final product testing string is suppressed by the liquid inlet joint 21 on body 2.
Pressure testing device of the present invention, when dismantling, first lays down baffle ring 6, then unloads intermediate head 4, the packer of test or tubing string can be removed, its convenient disassembly, be easy to change experimental tool finally by unloading top connection 3.This pressure testing device occurs damaging or when not conforming with testing requirements, only need changing corresponding parts, thus can effectively save test material, not need large-scale experiment equipment in relevant position, and structure is simple, is easy to processing.Intermediate head 4 and body 2 can the size of experimentally instrument be changed, and after experiment terminates, test packer or tubing string are removed and can carry out next time and test.
