Abstract
A core gripper is suitable for radial flow experiments of monolayer or multilayer in the field of petroleum geology. The core holder consists of a piston-type gripper of multilayer and a piston-type overburden pressure system. Separately, the top layer of the piston-type gripper of multilayer is a piston-type plug; the lowest layer of the piston-type gripper of multilayer is a core chamber of cavity-tape; and the middle layer of the piston-type gripper of multilayer is a combination of the piston-type plug and the core chamber of cavity-tape. The core overburden pressure is provided by the piston-type overburden pressure system which consists of a piston, a hydraulic cavity body, a chassis, a pressure bearing pillar, an upper pressure bearing baffle and a nut.
Description
The utility model relates to the core holding unit that use in a kind of oil geology field, is applicable to do the experiment of single or multiple lift Radial Flow.
At present, used clamper mostly is axial core holding unit in the core experiment, though come the simulated formation experiment that certain representativeness is arranged with this clamper, inequality with the actual formation situation, because the mobile Radial Flow that mostly is of stratum inner fluid, and usually be that multilayer flows simultaneously.Existing radially core holding unit can only be done the experiment of individual layer, and pressure index is not high, how based on as gas experiment.
The purpose of this utility model provides a kind ofly can do individual layer, can do the core holding unit that the multilayer rock core is radially tested again, and to gas, liquid is all applicable, and carries upper-coated pressure system.
The purpose of this utility model is achieved in that
1. designed multilayer piston type clamper.Its superiors are piston type plugs, and orlop is a cavity type core chamber, and the middle layer is the combination of piston type plug and cavity type core chamber.The piston type plug is pressed in core chamber's cavity during use.The internal diameter of the diameter of piston type plug and cavity type core chamber designs by the external diameter of used slabbed core in the experiment, and they go out 2-3mm greatly than the external diameter of slabbed core; The degree of depth of the thickness of piston type plug and core chamber's cavity is pressed the Thickness Design of slabbed core, guarantees axially to have enough length in order to sealing; Sealing O type ring cross-section is a rectangle, is assemblied on the plug end face right angle step on every side.There is rubber gasket the end face of plug and the bottom surface of cavity, play sealing rock core end face during experiment; In the centre of plug and the centre of rock core opening is arranged all, can be used as total inlet or total output mouth after being communicated with to get up, can be used to wellbore hole simulator, have a hole by the bottom, can be used as the layering inlet and also can be used as layering output mouth in the side of cavity.
2. designed the piston type upper-coated pressure system and provide the simulation burden pressure for multilayer piston type clamper.It is made up of piston, hydraulic chamber, chassis, compression struts, top pressure-bearing baffle plate, holding nut and clamp nut.Piston area is equal to or greater than piston type plug area.Compression struts is higher than the hydraulic chamber upper surface and is partly with the gong line, and pressure-bearing baffle plate two ends, top have circular hole, and its centre distance equates that with two compression struts centre distance diameter is greater than compression struts external diameter 2-3mm.Two compression strutses are supported it by the lower support nut after passing pressure-bearing baffle plate two circular holes, are compressed by the top clamp nut then.
Owing to adopted such scheme, the utility model that following advantage is arranged:
1. the clamper hierarchical design makes the user flexible in use, can do the experiment of individual layer Radial Flow, also can be radially contrast experiment of multilayer.If can cooperate baking oven to use, just can simulate High Temperature High Pressure, the real simulation strata condition.
2. sealing O type ring cross-section is a rectangle, cooperates plug end face right angle step on every side, has both guaranteed that sealing was reliable, guarantee again easy to loading and unloading, particularly in when dismounting, when upwards getting plug, O type circle can make that the operator can be easier to plug is taken out from landing on the step from cavity.
3. the piston diameter of upper-coated pressure system makes its diameter with plug identical or greater than the diameter of plug in design, like this, the pressure that promotes the liquid of piston will be consistent or proportional with the suffered pressure of rock core end face, be convenient to burden pressure is preset and controlled.
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is the overall wiring layout of multiple-lay core gripper radially.
The knot of 1. total inlets or output mouth 2. top pressure-bearing baffle plate 3. piston type plugs, 4. layering output mouths or inlet 5. piston type plugs and cavity type core chamber and body 6. cavity type core chamber 7. pistons, 8. hydraulic pressure 9. bases, 10. hydraulic chambers, 11. compression strutses, 12. rock cores, 13. rubber gasket 14.O type circles, 15. holding nuts, 16. clamp nuts that enter the mouth among Fig. 1
The superiors of clamper are piston type plugs 3 among Fig. 1, orlop is a cavity type core chamber 6, the middle layer is the combination 5 of piston type plug and cavity type core chamber, the cavity inner bottom surface of the end face of piston type plug 3 and cavity type core chamber 6 all has rubber gasket 13, be used to seal the both ends of the surface of rock core 12, around the end face of piston type plug 3 is a right angle step, be used to assemble the O type circle 14 that the cross section is a rectangle, O type circle 14 is used for guaranteeing the axial seal between piston type plug 3 and the cavity type core chamber 6, the centre of the knot of piston type plug 3 and piston type plug and cavity type core chamber and body 5 and rock core 12 all has opening, they link up as total inlet or output mouth 1, side in cavity type core chamber 6 has layering output mouth or inlet 4 by cavity bottom, the burden pressure of rock core 12 end faces is provided by piston 7 and top pressure-bearing baffle plate 2, the power of piston 7 comes from the pressure liquid that injects hydraulic chamber 10 from hydraulic pressure inlet 8, because top pressure-bearing baffle plate 2 weight are bigger, when dismounting, can earlier clamp nut 16 upwards be threaded to certain position, upwards revolve simultaneously with two holding nuts 15 then, top pressure-bearing baffle plate 2 is lifted.
