Abstract
The utility model discloses a flexibly adjusting top perforation azimuth instrument adopted by oil/gas wells. The utility model comprises an external shell and a flexibly adjusting top; wherein, the external shell is a double-layered structure composed of an outer layer and an inner layer, with a vacuum layer positioned between the outer layer and the inner layer. At the lower end of the external shell is provided with a bulkhead which goes into the inner layer of the external shell to realize a sealing of the external shell and vacuum layer, and between the bulkhead and the top is provided with an endothermic material. The utility model enjoys a perfect heat insulation effect and has a durable external temperature as high as 180 degrees centigrade. Meanwhile, both the outer layer and inner layer of the external shell adopt titanium alloy, thereby witnessing a marked rising of compression-resisting strength which is as high as 140 MPa and further endowing the utility model with a marked enlarged application scope.
Description
Technical field
The utility model relates to a kind of oil gas drilling equipment, is specifically related to the moving gyro perforation orientation instrument of transferring of a kind of oil gas well.
Background technology
The low permeability reservoir that suitable part is big for the exploitation difficulty, benefit is not high is arranged in CNPC, the natural gas resource, develop these reservoirs and must adopt the fracturing operation.In order to improve the effect of increasing production of pressure break, preferably to the fracture orientation with perpendicular to the orientation perforation of minimum level point power.Want to find out by the fracture identification log system earlier the orientation of fracture development for this reason, and then, after perforating gun is gone into the well, can accurately face toward the fracture orientation perforation by the orientation that the perforation orientation instrument is proofreaied and correct perforating gun.Existing perforation orientation instrument is generally the moving gyro perforation orientation instrument of transferring, be called " a kind of moving mode gyrolevel that is used to log well ", the patent No. as name and be the Chinese utility model patent of " 03266273.4 " a kind of equipment disclosing, it is made up of six unit, the damper of its middle front part is terminal to be connected with shell one end, the shell other end is connected with head harness, be connected with coasting body, gyro power cabin, microcomputer cabin and powerhouse dome in the enclosure in turn, its assemble sequence is to carry out toward two from middle.As everyone knows, well bores deeply more, and the temperature in shaft bottom is high more, and pressure is big more, and is just high more to the requirement of the bottom equipment that comprises the perforation orientation instrument, and the more direct embodiment of this requirement is in the requirement to shell.The perforation orientation instrument of prior art comprises that its shell of above-mentioned patent is the tubular structure of individual layer, that material is used morely is 45# steel and 40#Gr, thereby heatproof, withstand voltage all not high, instrument self heatproof does not often reach 125 ℃, and is withstand voltage only between 80～100MPa yet.Because the temperature of many oil and gas reservoirs, pressure often surpass above-mentioned value, make the application of perforation orientation instrument be subjected to many restrictions.
Summary of the invention
At existing perforation orientation instrument above shortcomings, the purpose of this utility model is to provide a kind of can significantly improve heatproof, the moving mode gyro perforation orientation instrument of withstand voltage oil gas well.
The technical solution of the utility model is achieved in that the oil gas well is with moving mode gyro perforation orientation instrument, comprise shell and place the interior moving accent gyro of shell, the described shell double-decker outer and the internal layer formation of serving as reasons, it between skin and the internal layer vacuum layer, be provided with plug in the shell lower end, plug enters the shell internal layer with shell and vacuum layer sealing, is provided with heat-absorbing material between plug and gyro.Shell skin of the present utility model and inner layer material are selected high-intensity titanium alloy for use.
The utility model adopts the ultrahigh vacuum adiabatic method because shell adopts double-decker, and inside and outside wall is handled through special process, and interlayer is thin especially, and the interval is 1～2mm only, makes the internal and external environment temperature isolated substantially.The lower end also is provided with efficient heat-absorbing material, so have fabulous heat-blocking action.This instrument requires the internal work temperature to be not more than 100 ℃, and the external temperature that can tolerate this moment reaches as high as 180 ℃.Simultaneously, shell skin and inner layer material are titanium alloy, and more existing 45# steel of compressive resistance and 40Gr improve a lot, and reach 140MPa.
Just because of the utility model heatproof, withstand voltagely all be improved largely, so its range of application obviously enlarges than prior art.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is Fig. 1 partial enlarged drawing.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 1 is a structural representation of the present utility model, because the moving accent of this oil gas well gyro perforation orientation instrument is an elongate articles, for outstanding expression invention place, among the figure instrument two ends is clipped, and it is identical with the prior art structure to clip part.The moving gyro perforation orientation instrument of transferring of oil gas well of the present utility model comprises columnar shell 1 and the moving accent gyro 2 that places in the shell 1.The same with prior art, the shell upper end is connected with damper, and the lower end is connected with head harness.Transfer the gyro except moving in the enclosure, upwards be connected with gyro power cabin, microcomputer cabin and powerhouse dome in turn.
Improvements of the present utility model are, shell 1 serve as reasons outer 3 and the double-decker that constitutes of internal layer 4, outer 3 and internal layer 4 between be vacuum layer 5.During concrete the processing, can independently process ectonexine earlier, again the ectonexine two ends be welded together respectively.Certainly, shell outer 3 and internal layer 4 also can be machined directly to one, and the centre is airtight cavity, and formation vacuum layer again is evacuated cavity.Be welded with plug 6 in the shell lower end, plug 6 enters shell internal layer 4 with shell and vacuum layer 5 sealings.Be provided with heat-absorbing material 7 at plug 6 and moving 2 on the gyro of transferring, heat-absorbing material 7 cooperates with shell internal layer 4 plug 6 and gyro 2 seal isolation, and described heat-absorbing material can be the Outlast fiber, high heat absorption and rafifinal composite material.Also be welded with lower union joint 8 in plug 6 another directions, be provided with vacuum draw passage 9 in plug 6, vacuum draw passage 9 is communicated with the vacuum pumping mouth on vacuum layer 5 and the lower union joint 10.
In order to improve the compressive resistance of shell, the skin 3 of this example shell and internal layer 4 materials are titanium alloy.
The utility model shell adopts double-decker, improved the tolerable temperature of instrument, and sheathing material adopts titanium alloy, then improved the proof pressure of instrument, its temperature tolerance reaches as high as 180 ℃, the pressure tolerance reaches as high as 140MPa, thereby has greatly expanded the range of application of this oil gas well with moving mode gyro perforation orientation instrument.
