Abstract
The utility model provides a special centralizer for a highly-deviated well, which comprises a centralizer body, blades and rollers. A jack screw for jacking a well measuring instrument is arranged inside the centralizer body, one of each blade is evenly arranged outside the centralizer body while the other ends extend towards the direction far away from the centralizer body, and the rollers are arranged at the ends, far away from the centralizer body, of the blades and capable of rolling along an inner wall of a casing pipe. By adding the rollers on the blades of the centralizer body, the special centralizer for a highly-deviated well realizes rolling friction between the centralizer and the casing pipe, greatly reduces frictional resistance of the well measuring instrument, and accordingly enables the well measuring instrument to be placed down to a deeper position.
Description
Technical field
The utility model relates to a kind of special-purpose centralizer that is used for high angle hole.
Background technology
Many loggers need measurement placed in the middle in the well logging process, placed in the middle in order to realize instrument, need on some logger shell centralizer be installed.Usually the centralizer that uses in well logging has two kinds: a kind of is the rubber centralizer, and another kind is the rigidity centralizer.The rubber centralizer generally uses at straight well because frictional resistance is bigger; Rigidity centralizer frictional resistance is less, generally uses at high angle hole.At present, along with the logger function from strength to strength, the weight of instrument is also more and more heavier, uses the rigidity centralizer to be difficult to logger is transferred to the target zone position even cause at some high angle holes.In addition, when instrument is heavier, use the rigidity centralizer, suffer big resistance easily, even logger can be transferred to the target zone position, also might below in the process since the excessive logger that makes of resistance be damaged.
The utility model content
The technical problems to be solved in the utility model provides a kind of multicore logger syndeton that need not change mechanical connecting structure stable connection multicore logger and crawl device.
In order to address the above problem, the utility model provides a kind of special-purpose centralizer that is used for high angle hole, comprising:
Centralizer body, described centralizer body inboard is provided with the jackscrew that is used to hold out against logger;
Blade, described blade one end evenly are arranged on the described centralizer body outside, and the other end is to extending away from described centralizer body direction;
Roller, described roller are arranged on the end of described blade away from described centralizer body, and can roll along described internal surface of sleeve pipe.
Further, described roller diameter is suitable with described blade height.
Further, the outstanding described blade height of described roller is about the roller diameter sixth.
Further, described roller is the abrasion-proof corrosion-proof corrosion material.
The utlity model has following advantage:
1, the utility model adopts and install roller additional on the blade of centralizer body, realizes the rolling friction of centralizer and sleeve pipe, has greatly reduced logging instrument instrument frictional resistance, thereby logger can be transferred to darker layer position.
2, roller size and permanent position are fit to transport logger in the utility model, and institute takes up space lessly, can improve the service efficiency of centralizer greatly.
3, the utility model roller adopts the abrasion-proof corrosion-proof corrosion material, can improve application life and reliability so that roller adapts to abominable working environment more.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Fig. 1 shows a kind of special-purpose centralizer structure schematic diagram vertical view that is used for high angle hole of the utility model;
Fig. 2 shows a kind of special-purpose centralizer structure schematic diagram sectional view that is used for high angle hole of the utility model;
Fig. 3 shows a kind of special-purpose centralizer user mode schematic diagram that is used for high angle hole of the utility model.
The specific embodiment
As shown in Figure 1-Figure 3, the utility model comprises centralizer body 1, blade 2 and roller 3.Centralizer body 1 is that rigidity is circular.Centralizer body 1 inboard is provided with jackscrew 4, and this jackscrew 4 is used to hold out against logger 6.Jackscrew 4 withstands in the logger 6 eave tile holes realizes and the closely cooperating of logger 6 that jackscrew 4 models are 6-M10 high strength screw.
Present used conventional logging instrument 6 external diameters have two kinds: a kind of is the 3-3/8 inch, and another kind is the 3-5/8 inch.Wherein the eave tile hole of 3-3/8 inch external diameter logger 6 correspondences is 4 hole five equilibriums, and the eave tile hole of 3-5/8 inch external diameter logger 6 correspondences is 6 hole five equilibriums.
The utility model adopts and install roller 3 additional on the blade of centralizer body 1, realizes the rolling friction of centralizer and sleeve pipe 7, has greatly reduced logger 6 frictional resistances, thereby logger 6 can be transferred to darker layer position.
In the utility model, roller 3 diameters and blade 2 are highly suitable.In addition, roller 3 outstanding blades 2 highly are about roller 3 diameter sixths.The radian on roller 3 surfaces is consistent with sleeve pipe 7 inwall radians.As required, can roller 3 quantity be set to 2, the utility model rolling transportation is surveyed and the intensity of instrument 6 to strengthen.
In the utility model, roller 3 is the abrasion-proof corrosion-proof corrosion material.Can adopt the materials of handling through modified stiffened such as 40 chromium as required.The utility model roller 3 adopts the abrasion-proof corrosion-proof corrosion material, can improve application life and reliability so that roller 3 adapts to abominable working environment more.
In sum; it below only is preferred embodiment of the present utility model; be not to be used to limit protection domain of the present utility model; therefore; all any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
