Abstract
A column sealing device relates to a sealing device of oil field profile adjustment well used for plugging the column. A fishing head (1) lower end in the utility model is fixedly connected with the upper end of a weight bar (2), the lower end of the weight bar (2) is movably connected with the upper end of a shaker (3), the lower end of the shaker (3) is fixedly connected with the upper end a seal section (4), the lower end of the seal section (4) is fixedly connected with the upper end of a positioner (5), the upper end of a locking head (6) is fixedly connected with the lower end of the positioner (5), and a cup type sealing element (4-1) is fixed in the lower part of the seal section (4) The utility model has the advantages of simple structure, convenient salvage, reliable column sealability, which can effectively prevent the profile adjustment agent fluid from entering into the lower tubing of the intended zone, thereby decreasing the blanking plug salvage workload.
Description
Technical field: the utility model relates to the sealing device that the oil field profile control well is used for the shutoff tubing string.
Background technology: what generally adopted in the oil field at present is fixed tubular column layering profile control mode, exactly the blanking plug of target zone is pulled out, the blanking plug of other non-target zone is changed the dead mouth of throwing, this mode pulling workload is bigger, part profile control well during construction causes under the profile control agent below target zone because profile control target zone bottom tubing string is not tight, can't replace out this part profile control agent when squeezing, cause the bottom tubing string to stop up, can't proceed dropping-fishing test.
The utility model content: the purpose of this utility model is a kind of tubing string sealing device of development, it should have simple in structure, pulling convenience, the tubing string sealing can prevent effectively that the profile control agent fluid from entering target zone bottom oil pipe reliably, reduces the characteristics of blanking plug pulling workload.The utility model is made up of fishing head 1, weighted lever 2, oscillator 3, seal section 4, at least one sealing cup 4-1, locator 5, elongated insertion part 6, fixedly connected with the upper end of weighted lever 2 in the lower end of fishing head 1, the upper end of the lower end of weighted lever 2 and oscillator 3 flexibly connects, fixedly connected with the upper end of seal section 4 in the lower end of oscillator 3, fixedly connected with the upper end of locator 5 in the lower end of seal section 4, fixedly connected with the lower end of locator 5 in the upper end of elongated insertion part 6, sealing cup 4-1 is fixed on the bottom in the seal section 4.During the utility model profile control, the tubing string sealing device taken off snap in the target zone eccentric injection mandrel, support sealing device by locator 5, sealing cup 4-1 expands under the effect of top weighted lever 2 and seals, when injecting profile control agent, sealing cup 4-1 is dead with profile control target zone lower tube column sealing, and profile control agent injects target zone by the inclined to one side hole on the target zone injection well downhole flow regulator.The utlity model has convenient, the tubing string sealing reliably of simple in structure, pulling, can prevent effectively that the profile control agent fluid from entering target zone bottom oil pipe, reduce the advantage of blanking plug pulling workload.
Description of drawings: Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment: present embodiment is made up of fishing head 1, weighted lever 2, oscillator 3, seal section 4, two sealing cup 4-1, locator 5, elongated insertion parts 6, fixedly connected with the upper end of weighted lever 2 in the lower end of fishing head 1, the upper end of the lower end of weighted lever 2 and oscillator 3 flexibly connects, fixedly connected with the upper end of seal section 4 in the lower end of oscillator 3, fixedly connected with the upper end of locator 5 in the lower end of seal section 4, fixedly connected with the lower end of locator 5 in the upper end of elongated insertion part 6, two sealing cup 4-1 are fixed on the bottom in the seal section 4.Between the upper end of the lower end of weighted lever 2 and oscillator 3 is to be threaded.Locator 5 is made up of locator main body 5-2, two locating detent 5-1, two locating shaft 5-3, and two locating detent 5-1 are fixed on the both sides, top of locator main body 5-2 by two locating shaft 5-3 respectively.
Claims (3)
