Abstract
The utility model discloses a high pressure plug with elastic dilated mechanism which is a tool used in the downhole for oil production, and is applied to technical processes, such as testing oil, workover, seal inspection, taking samples, pressure test, production proration, injection proration and testing, etc. The utility model adopts a hooking and linking mechanism composed of catch plates and cards, which is connected with the elastic dilated mechanism. When arrives in a specified position in the downhole, the device enables the outer diameter of a broadside elastic sealing ring to dilate and achieves a better effect of seal and high tension. When the device is dragged up, the outer diameter of the sealing ring shrinks applying to the proper performance of the device. Thus the utility model overcomes the defects of the existing plugs of poor sealed effect and difficult to be dragged up from and put into the downhole.
Description
The utility model relates in a kind of Petroleum Production the blanking plug that uses in the down-hole, is widely used in formation testing, well workover, tests envelope, sampling, pressure testing, joins in the activitiess such as product, injection allocation, test.
Blanking plug is a kind of important downhole tool, and the function that it will reach is a good airproof performance, removes conveniently.Record widely used blanking plug in the prior art in the 124th page in the oil recovery test and measuring handbook (petroleum industry publishing house in September, 1979 version), this blanking plug as shown in Figure 1, by fishing head, oil nozzle, main body, sealing ring, compositions such as plug, profile is a cylinder, above the liquid pass hole and following three road O RunddichtringOs are arranged respectively, solve sealing problem, be characterized in simple in structure, fabricating cost is low, but because the seal section of this blanking plug only is made up of each three road O RunddichtringO up and down, the scalable amount of external diameter is very little, remove very inconvenient, sometimes O type circle is routed up, and makes to remove to be difficult to carry out, and the reason of the defective of this plug structure itself and the accuracy of manufacture causes its sealing effectiveness also relatively poor in addition, be difficult to sealed high pressure, especially relatively poor in seating nipple internal diameter crudy, or pull, under the situation of scratch, it is poorer to seal.
The purpose of this utility model is to provide a kind of can overcome above-mentioned deficiency, have the effect of better seal high pressure, and removes the blanking plug of convenience, easy operating.
The movable elastic dilated type blanking plug of high pressure of the present utility model, comprise fishing head, oil nozzle, main body, sealing ring, the core of this blanking plug are that a cover links mechanism by what clamp and card were formed, and there is a pivot clamp centre, clamp can pivot, clamp one end is supported on the little spring, has restoring force when making its work, and card is fixed on the connecting rod by a pin, connecting rod can move up and down under the effect of big spring, before going into the well, clamp and card link mutually, make spring compression, storage power, go into the well when arriving assigned address, top cover and seating nipple step bump, clamp and card are thrown off, spring energy discharges, connecting rod moves downward, and the driving body that links to each other with connecting rod moves downward thereupon, is processed with tapered segment on the driving body, this tapered segment contacts with the decorative pearl on top of an official cap, decorative pearl on top of an official cap outside is a top flat, and top flat is equipped with elastic seal ring outward, when driving body moves downward, its conical surface promotes the decorative pearl on top of an official cap and radially outward moves, and then the promotion top flat, making the sealing ring expansion, the sealing liquid outlet is the annular space at two ends up and down.Sealing ring is a wide sealing ring, and external surface is processed with several convex line, and less because of its cross section, elasticity is bigger, can reach the better seal effect in more coarse sealing surface, and also can reach preferable sealing effectiveness under higher operating pressure.Wide sealing ring is equipped with gland up and down, and the O RunddichtringO is housed on the gland, and the O RunddichtringO plays depressurization, and play the guiding role in the process of removing.Fishing head is equipped with on the top of blanking plug, trips out usefulness for salvaging, and oil nozzle is equipped with in the lower end of blanking plug, and the size of oil nozzle is adjustable.Adjustment ring in this blanking plug works to adjust the driving body move distance, adjusts under the ring thrust bearing is housed, the resistance when adjusting to reduce.
High pressure elastic dilated type blanking plug of the present utility model can satisfy the seal request under the multiple applying working condition.Expand and shrinks because of it can lean on performance of machinery itself, so remove more conveniently, and this is not easy to wear in the process of removing, thereby has the application life of length.High pressure elastic dilated type blanking plug is not only the necessary instrument in the production and injection proration, can also be connected with various testers, enrolls laminated distributor under well data, the sealing of checking sealing of packer under the high pressure sealing condition exactly.
Below in conjunction with the given embodiment of accompanying drawing 1 to 3, the utility model is described in detail.
Accompanying drawing 1 is the structure chart of blanking plug in the prior art.
Accompanying drawing 2 is structure charts of the movable elastic dilated type blanking plug of high pressure.
Accompanying drawing 3 is working state figures of the movable elastic dilated type blanking plug of high pressure.
The movable elastic dilated type blanking plug of the given high pressure of embodiment is by fishing head (1), adjust ring (2), silk head (3), thrust bearing (4), overcoat (5), little spring (6), clamp (7), pivot (8), card (9), top cover (10), pin (11), connecting rod (12), screw (13), store cover (14), big spring (15), the decorative pearl on top of an official cap (16), wide sealing ring (17), O type circle (18), anti-collision block (19), main body (20), driving body (21), top flat (22), gland (23) and oil nozzle (24) are formed.When ground, ring (2) is adjusted in rotation, make on the connecting rod (12) and carry, driving body (21) rises thereupon, clamp (7) and card (9) link mutually, and at this moment big spring (15) is compressed, and the decorative pearl on top of an official cap (16) is in the minimum diameter place of driving body (21) cone, therefore the external diameter of wide sealing ring (17) is minimum, can successfully drop into the movable elastic dilated type blanking plug of high pressure in the well like this.After blanking plug arrives assigned address, its top cover (10) bumps against with the seating nipple step, behind the bump, clamp (7) and card (9) are thrown off, the energy of big spring (15) discharges, and promotes driving body (21) and moves down, and the decorative pearl on top of an official cap (16) is radially outward moved, drive an external diameter of wide sealing ring (17), reach the purpose of sealing.
The movable elastic dilated type blanking plug of high pressure of the present utility model is used in when data is enrolled in layering in eccentric injection mandrel or the eccentric production mandrel, available one section sealing (promptly having only wide sealing ring together), and its operating principle is identical with two sections sealings.
If the utility model is used for water blockoff, water detection, tests envelope, well workover etc., then adopt the blanking plug (among ginseng Fig. 2 between two sections sealings imaginary line) in aneroid hole, be used for test, join product, injection allocation, pressure measurement, sampling etc., then to adopt the blanking plug in liquid hole.
