Abstract
The utility model relates to an all-water value sampling mechanism of a production profile logging instrument and mainly solves the problems of poor sealing performance of a sealing cavity and easy damage occurrence caused by nonuniform stress of umbrella ribs of the existing all-water value sampling mechanism of the production profile logging instrument. The all-water value sampling mechanism is characterized in that the outer part of a center pipe (5) is respectively provided with a lower umbrella support seat (4) and an upper umbrella support seat (9), the inner surface of the lower umbrella support seat (4) and the outer surface of the upper umbrella support seat (9) are respectively provided with umbrella rib grooves uniformly distributed in the circumferential direction, umbrella ribs (6) are arranged in the umbrella rib grooves, and a sealing ring (8) is arranged between the inner surface of the upper umbrella support seat (9) and the center pipe (5). The all-water value sampling mechanism of the production profile logging instrument has the advantages that liquid in a sampling flow passage is completely sealed, the all-water value measurement is accurate, the umbrella rib stress is uniform, and the damage cannot be easily caused.
Description
Technical field
The utility model relates to a kind of oilfield field, the full water number sampling mechanism of a kind of specifically production profile logging appearance.
Background technology
Impedance type production profile logging appearance is a kind of annular space water detection logging instrument of crossing, and utilizes measurement fluid conductivity principle to measure the oil well liquid-producing specific retention.The present full water number sampling mechanism of impedance type production profile logging appearance by a umbrella muscle in instrument one side transmission, discontinuity during the umbrella transmission, transmission umbrella muscle damages easily even fractures; And the sampling annular seal space is directly sealed by metal, can't accomplish to seal fully.
Summary of the invention
In order to overcome the deficiency of the fragile and annular seal space sealing difference of the full water number sampling mechanism of existing production profile logging appearance umbrella muscle discontinuity; The utility model provides a kind of production profile logging appearance full water number sampling mechanism; It is accurate that the interior liquid of the full water number sampling mechanism sampling of this production profile logging appearance runner seals, measures full water number fully, and the umbrella muscle is stressed evenly, not fragile.
The technical scheme of the utility model is: the full water number sampling mechanism of a kind of production profile logging appearance; Comprise central tube; On the described central tube inlet opening is arranged, described central tube outside is respectively equipped with the subumbrella bearing and goes up the umbrella bearing, and described subumbrella props up base inner surface and last umbrella bearing external surface is equipped with the umbrella muscle groove that several circumferencial directions are uniformly distributed with; Umbrella muscle groove is built-in with the umbrella muscle, and described upward umbrella props up between base inner surface and the central tube and is provided with sealing ring.
Described umbrella muscle is 16, between connect by umbrella cloth.
Described sealing ring is two, is separately positioned on the two ends of inlet opening.
The utlity model has following beneficial effect: owing to take such scheme, the umbrella muscle is that several and circumferencial direction are uniformly distributed with, and the umbrella muscle is stressed evenly when transmission like this, and is not fragile; Be provided with sealing ring between last umbrella bearing and the central tube, the interior liquid of sampling runner is sealed fully, it is accurate to measure full water number; This mechanism structure is simple, is easy to realize, can be applied directly on original logging instrument, does not increase manufacturing cost.
Description of drawings
Fig. 1 is the structural representation of the utility model when opening inlet opening;
Fig. 2 is the structural representation when opening current collecting umbrella;
Fig. 3 is the structural representation when closing inlet opening.
4-subumbrella bearing among the figure, 5-central tube, 6-umbrella muscle, 7-inlet opening, 8-sealing ring, the last umbrella bearing of 9-, 10-reducer union.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
To shown in Figure 3, the full water number sampling mechanism of a kind of production profile logging appearance comprises central tube 5 by Fig. 1, and the upper end of central tube 5 connects reducer union 10, on the described central tube 5 inlet opening 7 is arranged, and feed liquor is recalled 73 slotted holes being uniformly distributed with for circumferencial direction.Described central tube 5 outsides are respectively equipped with subumbrella bearing 4 and go up umbrella bearing 9,4 gearings of described subumbrella bearing, and inner surface is provided with the umbrella muscle groove that several circumferencial directions are uniformly distributed with; Last umbrella bearing 9 external surfaces are provided with umbrella muscle groove, and umbrella muscle groove is built-in with umbrella muscle 6, and umbrella muscle groove is 16; Therefore, umbrella muscle 6 is 16, is connected by umbrella cloth between the adjacent umbrella muscle 6; Form current collecting umbrella, play the effect that makes the liquid afflux after opening.Described umbrella muscle 6 is the spring steel material, good toughness.Described going up between umbrella bearing 9 inner surfaces and the central tube 5 is provided with sealing ring 8, and sealing ring 8 is two, is arranged in the two ends of inlet opening 7.
When carrying out the sampling of full water number; Subumbrella bearing 4 drives on umbrella muscle 6 and the last umbrella bearing 9 and moves, last umbrella bearing 9 contact reducer unions 10 back stop motions, and umbrella bearing 9 is opened inlet opening 7 fully on this moment; The depressurization state; Subumbrella bearing 4 continues to move on the drive umbrella muscle 6, and umbrella opens to the afflux state, at this moment apparatus measures flow and mixed phase value; Subumbrella bearing 4 drives umbrella muscle 6 and moves down, umbrella muscle 6 closures, and subumbrella bearing 4 continues to drive umbrella muscle 6 and moves down with last umbrella bearing 9, and last umbrella bearing 9 seals inlet opening 7 fully, and liquid is in sealing state in the runner, the full water number of apparatus measures this moment.
Claims (3)
1. full water number sampling mechanism of production profile logging appearance; Comprise central tube (5); Inlet opening (7) is arranged on the described central tube (5); It is characterized in that: described central tube (5) outside is respectively equipped with subumbrella bearing (4) and goes up umbrella bearing (9); Described subumbrella bearing (4) inner surface and last umbrella bearing (9) external surface are equipped with the umbrella muscle groove that several circumferencial directions are uniformly distributed with, and umbrella muscle groove is built-in with umbrella muscle (6), and described going up between umbrella bearing (9) inner surface and the central tube (5) is provided with sealing ring (8).
