Abstract
The utility model relates to a casing thermal stress compensator, in particular to a temperature sensitive casing thermal stress compensator. The temperature sensitive casing thermal stress compensator is technically characterized in that: the temperature sensitive casing thermal stress mainly consists of an inner cylinder, a cylinder tube, a piston, a shear pin, a sliding sleeve, a ring key and an outer cylinder. The inner tube and outer tube is connected through the ring key, which is locked by the sliding sleeve. The sliding sleeve and inner tube are fixed by the shear pin. The inner tube is provided therein with the cylinder tube, which is provided thereon with the piston. The cylinder tube, inner tube and piston form a closed cavity, which is filled with temperature sensitive medium. The temperature sensitive casing thermal stress compensator provided by the utility model has the benefits that the capacity of bearing the tensile force and pressure is improved; and the mechanism acts and the device works when the casing reaches a certain temperature during the thermal recovery and thermal injection processes, which prevents the possibility of action failure of the device in advance.
Description
Technical field
The utility model relates to a kind of sleeve pipe thermal stress compensation device, particularly a kind of heat-sensitive type sleeve pipe thermal stress compensation device.
Background technology
Annotate in the activities in petroleum thermal recovery, heat, the big reason that sleeve pipe damages is a pressurized after sleeve is heated, and is drawn after the cooling, causes screw thread to destroy or casing deformation.For this reason, 1 ~ 2 cover thermal stress compensation device is installed,, is avoided sleeve pipe to damage to eliminate or to alleviate the sleeve pipe internal stress in the sleeve pipe appropriate location.
What generally use at present is shear pin formula thermal stress compensation device, connects with shear pin between the inner/outer tube.This thermal stress compensation device exists following shortcoming or deficiency: 1. in the lower tubular column process, be hampered, can shift to an earlier date the shear pin pin, cause the thermal stress compensation device to lose efficacy; 2. bear the suspending weight ability.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of heat-sensitive type sleeve pipe thermal stress compensation device is provided, and adopts the bulbs of pressure of thermal media; Promote piston motion; Open the key that is pinned by sliding sleeve, urceolus and inner core separate, under the effect of the sleeve pipe internal stress of being heated; Inner core, urceolus relative motion realize the compensating jacket stroke.
Its technical scheme is: mainly be made up of inner core, cylinder barrel, piston, shear pin, sliding sleeve, ring key, urceolus, described inner core is connected through ring key with urceolus, and sliding sleeve pins ring key, and with shear pin sliding sleeve and inner core is fixed; Be provided with cylinder barrel in the described inner core, cylinder barrel is provided with piston, and cylinder barrel and inner core, piston form an airtight cavity, charge into thermal media at closed cavity.
Above-mentioned ring key is embedded between urceolus and the inner core in the annular groove, and segmentation is arranged.
The beneficial effect of the utility model is: the one, and the ability of bearing pulling force and pressure is strong; The 2nd, in thermal recovery, when heat is annotated uniform temperature, mechanism action, device works; The possibility of having avoided device action in advance to lose efficacy.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: inner core 1, cylinder barrel 2, piston 3, shear pin 4, sliding sleeve 5, ring key 6, urceolus 7.
The specific embodiment
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly is made up of inner core 1, cylinder barrel 2, piston 3, shear pin 4, sliding sleeve 5, ring key 6, urceolus 7, and described inner core 1 is connected through ring key 6 with urceolus 7, and sliding sleeve 5 pins ring key 6, and with shear pin 4 that sliding sleeve 5 is fixing with inner core 1; Be provided with cylinder barrel 2 in the described inner core 1, cylinder barrel 2 is provided with piston 3, and cylinder barrel 2 forms an airtight cavity with inner core 1, piston 3, charges into thermal media at closed cavity; Above-mentioned ring key 6 is embedded between urceolus 7 and the inner core 1 in the annular groove, and segmentation is arranged; The temperature design size that shear pin 4 can be as required in addition.
During use, when environment was raised to uniform temperature, thermal media expanded, and promoted piston 3 and moved; Shear pin 4 is cut off, and piston 3 promotes sliding sleeve 5 and moves, when the annular space of sliding sleeve 5 is aimed at ring key 6; Ring key 6 falls in the annular space, but inner core 1 separates with urceolus 7 and relative motion, realizes the stress compensation function.
