Description
Technical field
The utility model relates to the fastening devices of downhole testing instrument, relates in particular to a kind of downhole testing instrument hanger.
Background technology
In the field produces test process; Often will log well sub-surface pressure build-up curve or pressure decline curve; The pressure that the part Pressure Curve in Oil Testing Well needs pressure bomb accurately to write down the pumping process changes; Change through analyzing pressure, dynamic oil level etc. in the time of can calculating pumping number of times, pumping, thus carry out the pumping effect assessment.Usually the method that adopts is to use the down-hole suspension arrangement, by the suspension of slips tube, holds pressure gauge by spring and plug down and also is fixed in the oil pipe with two screws on the former pressure bomb holder tube; Complicated operation, heaviness, and the narrow pumping effect that influences of internal channel; The down-hole suspension arrangement one that existing market is used is that expense is high, and secondly result of use is all not ideal enough, and suspension is firm and cause tester to fall into the down-hole often; Not only influence oil well production, also can cause very big economic loss.Therefore, we press for a kind of not only simple to operate, but also safe and reliable hanger, to guarantee the ordinary production of oil well.We according to the shake that forms vibrations in the test because of analyzing, self design a kind of downhole testing instrument hanger that is used for damping.This hanger has the vertical and horizontal cushioning effect.Vertically damping is mainly used in the decay to vertical vibrations, and laterally damping is mainly used in the decay to horizontal mechanical shock.Thereby reach vertically certain attenuation being arranged, realized the purpose of protection electronic pressure gauge with mechanical shock radially.
Summary of the invention
The utility model technical problem to be solved provides a kind of both simple, convenient, safe and reliable again hanger, to guarantee the ordinary production of oil well.
The technical scheme that the utility model adopted is: a kind of downhole testing instrument hanger, include tubular body, and the upper end of tubular body is provided with handle, and the lower end of tubular body is connected to joint; Tubular body is set with location fork, upper spring, suspended prong, lower spring from top to bottom successively, pitch the location down.
Press such scheme, the outer circumference diameter of described suspended prong is than the big 2-3mm of interior diameter of down-hole oil tube.
Press such scheme, described suspended prong includes the suspension annulus, establishes 4 suspension fork arms on the suspension annulus.
Press such scheme, described location fork and the following little 1-2mm of interior diameter that locatees fork than down-hole oil tube of going up.
Press such scheme, described upward location fork and following location are pitched and are included the location annulus, and the location annulus is provided with 4 location fork arms.
Press such scheme, the lower end of described joint is provided with the screw socket that joins with tester.
Press such scheme, the size specification of described upper spring and lower spring is identical with highly.
Can this device easily be fixed on the oil pipe through the suspended prong of somewhat larger in diameter, adopt the approximate location fork of diameter and pipe aperture simultaneously, prevent this device rocking in oil pipe in the oil pipe inside diameter; The spring of installing between suspended prong and the location fork plays the damping, buffering effect.This apparatus structure is simple, and is easy for installation, and damping effect is remarkable.
The beneficial effect of the utility model is: 1, simple in structure, practical.2, easy to operate, reliable.3, can use manpower and material resources sparingly, reduce production costs.4, be provided with damping spring, the assurance tester is steadily gathered data.5, be provided with the location fork, can slow down the shaking amplitude of tester in oil pipe, tester is not collided with tubing wall.6, easy for installation, quick.

The specific embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4; A kind of downhole testing instrument hanger; Include tubular body 6; The upper end of tubular body 6 is provided with handle 1, and the lower end of tubular body 6 is connected to joint 5, and tubular body 6 is with location fork 2, upper spring 3, suspended prong 4, lower spring 3-1 from top to bottom successively and locatees fork 2-1 down; The described location fork 2 of going up includes the location annulus with location fork 2-1 down and is located at 4 location fork arms on the annulus of location with ring, and the described little 1mm of interior diameter that goes up the outer circumference diameter of location fork 2 and location fork 2 down than down-hole oil tube 9; Described suspended prong 4 includes suspension annulus and 4 suspension fork arms, and suspended prong 4 is than the big 2-3mm of interior diameter of down-hole oil tube 9, so the suspension fork arm of suspended prong 4 hangs on the box cupling place of two oil pipes 9 in down-hole; Described joint 5 is provided with the screw socket that is connected with tester 7.
In order to reach better damping, buffering effect, the upper spring 3 and the lower spring 3-1 of available same size specification, and upper spring 3 is the same at the height under the free state with lower spring 3-1.
The external diameter of the above handle 1 is greater than the interior diameter of last location fork 2, and the external diameter of said joint 5 is greater than the interior diameter of locating fork 2-1 down.
Suspended prong 4 sizes are slightly larger than oil pipe 9 interior diameters of entering to be installed, and purpose is between the box cupling that is stuck in adjacent oil pipe 9, fixes this device, steady testing instrument 7.Location fork 2 undersized are in oil pipe 9 internal diameters, and purpose is to reduce the shaking amplitude of this device in oil pipe 9, and stable firmly tester 7 prevents that vibrations from damaging tester 7.The spring 3 that suspended prong 4 is installed up and down can play the damping, buffering effect.The size and the tester to be installed 7 of the joint 5 of body 6 lower ends are supporting, and interface can adopt connected modes such as screw thread, simultaneously sealing ring can be installed, and prevent that tester 7 from moving back button.During use, connection tester 7 under joint, afterbody location fork 2-2 can be installed in tester 7 lower ends.Block up 8 at the bottom of the fork second line of a couplet of afterbody location, it is circular that the stifled cylindrical in the end can be awl.
Suspended prong 4 described in the present embodiment adopts quenched and tempered steel to process, and last location fork 2, following location fork 2-1 and afterbody location fork 2-2 employing rubber are processed.
The above; Only being the preferred embodiment of the utility model, is not that the utility model is done any pro forma restriction, and those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification; Equivalent variations or modification all drop in the protection domain of the utility model.
