Abstract
The utility model relates to an under-well cable packer, mainly solving the problems in the background techniques and characterized in that: the upper and the lower ends of a seal connecting sleeve(1) and an external central pipe(2) have through holes(4) which are inward inclined and communicated with a ring-shaped groove(3), with the seal connecting sleeve(1)outside of the through holes(4) having a counterbore(5) which is orderly provided with a spacer(6) and a sealing ring(7) from the lower side to the upper side; the seal connecting sleeve(1) on the upper side of the sealing ring(7) is connected with a press cap(8) through a screw thread. The under-well cable packer has the advantages of low cost and simple structure.
Description
Technical field:
The utility model relates to the used packer in down-hole, especially down-hole cable-passing packer in the oil recovery field, oil field.
Background technology:
At present, for cable under satisfied isolation to different oil reservoirs in the producing well, monitoring needs are in well, and because of packer is arranged in the sleeve pipe, cable is worn to be pass by.The packing that can cross cable at present is that marine oil field uses, this packer cost height, and external diameter is big, is not suitable for 140 millimeters sleeve pipes of diameter, does not satisfy the needs in oil field, land.
The utility model content:
In order to solve the problem in the background technology, the utility model provides a kind of down-hole cable-passing packer, and it is low that this down-hole cable-passing packer has a cost, characteristic of simple structure.
The technical solution of the utility model is: this down-hole cable-passing packer comprises annular groove, exterior central tube and the sealed adapter sleeve that inner central tube is outer, sealed adapter sleeve and exterior central tube have the through hole that slopes inwardly and communicate with annular groove in two ends up and down, the through hole outer end is tightly connected and has put threaded counterbore, be equipped with pad, sealing ring in the counterbore from the bottom to top successively, the sealing ring upper end is tightly connected and puts by the pressure cap that has been threaded.
The utlity model has following beneficial effect: this down-hole cable-passing packer is owing to take such scheme, cable passes through packer by through hole, do not having to change under the function situation of existing packer, satisfy isolation, monitoring and control, realize sealing by sealing ring and pressure cap simultaneously different oil reservoirs in the producing well.And simple in structure, low cost of manufacture helps applying.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-sealed adapter sleeve among the figure, 2-exterior central tube, 3-annular groove, 4-through hole, 5-counterbore, 6-pad, 7-sealing ring, 8-pressure cap.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this down-hole cable-passing packer comprises annular groove 3, exterior central tube 2 and the sealed adapter sleeve 1 that inner central tube is outer, sealed adapter sleeve 1 and exterior central tube have the through hole 4 that slopes inwardly and communicate with annular groove 3 in two ends about in the of 2, on the through hole 4 outer end sealed adapter sleeves 1 threaded counterbore 5 is arranged, be equipped with pad 6, sealing ring 7 in the counterbore 5 from the bottom to top successively, on the sealing ring 7 upper end sealed adapter sleeves 1 by the pressure cap 8 that has been threaded.
During actual the use, at first cable being passed pressure cap 8, sealing ring 7, pad 6 and through hole 4 enters in the annular groove 3, pass from the through hole 4 of annular groove 3 lower ends, pass pad 6, sealing ring 7 and pressure cap 8 more successively, again two pressure caps 8 are tightened, together be lowered in the well with packer at last, thereby, realize the purpose that cable passes through packer not changing under other function situation of existing packer.Because of only having through hole 4 in two ends about in the of 2, on the through hole 4 outer end sealed adapter sleeves 1 the cable fixing seals is installed, just pad 6, sealing ring 7 and pressure cap 8 at sealed adapter sleeve 1 and exterior central tube, so it is simple in structure, low cost of manufacture, constructing operation is convenient, helps applying.
In sum, this sealer for cable penetrating under well has low, the simple in structure characteristics of cost.
