Abstract

The utility model relates to a kind of scall CORING TECHNOLOGY field, and particularly one is cored and used pressurizing adaptor.The safety joint of this device, centralizer and urceolus are threaded in turn, piston upper end to be connected on safety joint inwall by shear pin and can with the slipper seal of safety joint inwall, piston inner wall is provided with the ball seat matched with pressurizing ball, piston is threaded bearing box, in bearing box, bearing is installed, bearing holder (housing, cover) is contained in outside tap, and tap sidewall has passage.The utility model achieves pressurizing adaptor and coring tool is designed to integral type, cancels extra pressurizing adaptor, the time of shackle on minimizing instrument, improves timeliness of coring, and reduces coring tool cost.Overcoming existing pressurizing adaptor with coring tool is two parts be separated, and need distinguish disassembly and assembly pressurizing adaptor and coring tool, reduces timeliness of coring, and increases the deficiency of instrument cost.

Description

One is cored and is used pressurizing adaptor
Technical field:
The utility model relates to a kind of scall CORING TECHNOLOGY field, and particularly one is cored and used pressurizing adaptor.
Background technology:
Scall is cored and is widely used fluid power adding pressure type instrument, is built the pressure by pressurizing adaptor, and piston promotes inner core and moves, and impels core grabber flexural deformation to cut off and support rock core.Pressurizing adaptor and coring tool are two parts be separated, disassembly and assembly pressurizing adaptor and coring tool need be distinguished, the upper lower body at every turn must dismantling separately pressurizing adaptor, to check the damaged condition of pressurizing piston, causing monotubular to core the upper shackle time with regard to increasing about 1 hour, greatly reducing timeliness; Simultaneously extra pressurizing adaptor, also directly increases instrument cost.
Utility model content:
The technical problems to be solved in the utility model is to provide one and cores with pressurizing adaptor, the arrangement achieves pressurizing adaptor and coring tool is designed to integral type, cancel extra pressurizing adaptor, the time of shackle on minimizing instrument, improve timeliness of coring, reduce coring tool cost.Overcoming existing pressurizing adaptor with coring tool is two parts be separated, and need distinguish disassembly and assembly pressurizing adaptor and coring tool, reduces timeliness of coring, and increases the deficiency of instrument cost.
Technical solution adopted in the utility model is: one is cored with pressurizing adaptor, comprises safety joint and piston; Safety joint, centralizer and urceolus are threaded in turn, piston upper end to be connected on safety joint inwall by shear pin and can with the slipper seal of safety joint inwall, piston inner wall is provided with the ball seat matched with pressurizing ball, piston is threaded bearing box, in bearing box, bearing is installed, bearing holder (housing, cover) is contained in outside tap, and tap sidewall has passage.
The beneficial effects of the utility model are: the utility model and coring tool are designed to integral type, cancel extra pressurizing adaptor, the time of shackle on minimizing instrument, improve timeliness of coring, and reduce coring tool cost.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As shown in Figure 1, one is cored with pressurizing adaptor, comprises safety joint 1 and piston 3; Safety joint 1, centralizer 5 and urceolus 9 are threaded in turn, piston 3 upper end to be connected on safety joint 1 inwall by shear pin 2 and can with the slipper seal of safety joint 1 inwall, piston 3 inwall is provided with the ball seat matched with pressurizing ball 4, piston 3 lower end is threaded bearing box 6, bearing 7 is installed in bearing box 6, bearing 7 is sleeved on outside tap 8, and tap 8 sidewall has passage.
Be slipper seal between piston 3 and safety joint 1, construction of coring, piston 3 inside keeps unimpeded, and drilling fluid enters tap 8 place by piston 3 and shunts, and enters inner/outer tube annular space; Core after terminating, pressurizing ball 4 is dropped into from ground, pressurizing ball 4 blocks piston 3 passage, in piston 3, form high pressure and cut off shear pin 2, promoting piston 3 descending, after the descending segment distance of piston 3, seal failure between piston 3 and safety joint 1, re-establish runner, pump pressure declines, and cuts the heart and completes.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
