Abstract
The utility model relates to a shock absorption protection holding tube of an underground testing electronic pressure gage of an oilfield testing formation, wherein an outer tube, a middle tube, an inner tube (2,13,12) are formed between an upper joint and a lower joint (1,16), the two ends of the middle tube are connected with an upper core retainer plate and a lower core retainer plate (5,20) through an upper convex ring joint and a lower convex ring joint (8,21) which are connected with the thread, the two core retainer plates are respectively sleeved with a plurality of elastic elements (3,4,6), the two ends of the inner tube are respectively padded with a plurality of elastic elements (9,10,11,19), a righting gum cover (7) is arranged between the outer tube and the middle tube, the electronic pressure gage is arranged in the inner tube through three layers absorbs the shock layer by layer, thereby being capable of eliminating an gigantic impact force of a detonation wave which is produced at the blasting moment of a hole projectile to the electronic pressure gage.
Description
(1) technical field:
The utility model relates to the downhole testing electronic pressure gauge shock-absorbing protecting holder tube on oilfield test stratum.
(2) background technology:
Electronic pressure gauge is the precision instrument in the formation testing work, and the vibrations of any tubing string all can influence measuring accuracy, and strenuous vibration also can shake electronic pressure gauge bad, causes the failure of test job, causes huge man power and material's waste.Common manometer is just packed pressure gauge one into and is held in the palm in the tube, a spring is equipped with in the bottom, top is fixed or is also added a spring, such holder tube is applicable to just in the smaller testing string of simple vibrations that bigger occasion is then inapplicable for shaking, and particularly does in the tubing string at the perforating test connection, perforating bullet is in instant of detonation, produce huge detonation wave, make testing string produce huge vibrations, can be bad the electronic pressure gauge shake.
(3) utility model content:
Technical problem to be solved in the utility model is at the problem that exists in the background technology, and a kind of to be suitable for vibrations bigger and provide, and is particularly suitable for making downhole testing electronic pressure gauge shock-absorbing protecting holder tube on the tubing string at perforating test connection.
The invention for solving the technical problem can reach by following technical solution: the upper and lower spring core retainer plate that stretches to the middle part, the upper and lower convex ring joint that is threaded are housed in be threaded on upper and lower joint ectosome urceolus, the body, and middle tube is threaded between upper and lower ring joint; Sitting on upper and lower convex ring joint down, upper ring surface has several ring elastic parts, is fixed with inner core between two groups of elastic components; On upper and lower joint inner face and corresponding upper and lower convex ring joint towards on upper and lower spring core retainer plate, being with several elastic components between the upper and lower anchor ring; Outside, on middle tube, be with in the ring cavity between the middle tube and set upright gum cover, in its both sides spacing clip is installed.
In such scheme, between the upper and lower convex ring joint down, sit spring stack, thick rubber pad, thin rubber cushion and two footpath Capsules that annular is arranged on the upper ring surface.Between two footpath Capsules, be fixed with inner core.On upper and lower joint inner face and corresponding upper and lower convex ring joint towards on upper and lower spring core retainer plate, being with little rubber cushion, spring stack, big rubber cushion between the upper and lower anchor ring and setting upright gum cover.Outermost layer holder tube the inside is a middle level holder tube; be that internal layer holder tube and a length adjustment bar are to adapt to the electronic pressure gauge of different length inside the middle level holder tube; adding rubber by end spring between interior three layers of holder tube in outer sets upright rubber device with the middle part and is connected; the rubber protective sleeve internal layer holder tube of packing into is equipped with at the outside two ends of electronic pressure gauge; like this; by three layers of holder tube damping successively, eliminated detonation wave that perforating bullet produces in instant of detonation fully to electronic pressure gauge huge impact power.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: the utility model is because only need add two-layer protection tube on the basis of original single ply protective tube; and be to form between every layer of protection tube by the various combination structure that rubber adds spring; and an adjusting lever has been added in second layer protection tube inside; it can and protect the electronic pressure gauge carrying of the various sizes of want RIH size; be the protective device of downhole testing instrument, the pressure when writing down the pressure variation of purpose well section constantly and carrying out various construction operation along with the operation of tester switch well then changes.Use the shock attenuation device of this structure,, also can not shake badly, simplified the structure and the operational procedure of striding every the perforating test tubing string even electronic pressure gauge is far away apart from ten meters of perforating guns.
(4) description of drawings:
Accompanying drawing is that this holder tube is installed half-sectional view.
(5) embodiment:
Below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:
Shown in accompanying drawing: at upper and lower joint (1,16) be threaded on the ectosome the upper and lower spring core retainer plate (5,20) that stretches to the middle part, the upper and lower convex ring joint (8,21) that is threaded are housed in urceolus 2, the body, tube 13 between upper and lower ring joint (8,21), being threaded; Sitting on upper and lower convex ring joint (8,21) down, upper ring surface has several ring elastic parts, is fixed with inner core 12 between two groups of elastic components; On upper and lower joint (1,16) inner face and corresponding upper and lower convex ring joint (8,21) towards on upper and lower spring core retainer plate (5,20), being with several elastic components between the upper and lower anchor ring; Outside, on middle tube 13, be with in the ring cavity between the middle tube (2,13) and set upright gum cover 14, spacing clip 15 is installed in its both sides.
In such scheme, between the upper and lower convex ring joint (8,21) down, sit spring stack 9, thick rubber pad 10, thin rubber cushion 11 and two footpath Capsules 19 that annular is arranged on the upper ring surface.Between two footpath Capsules 19, be fixed with inner core 12.On upper and lower joint (1,16) inner face and corresponding upper and lower convex ring joint (8,21) towards on upper and lower spring core retainer plate (5,20), being with little rubber cushion 3, spring stack 4, big rubber cushion 6 between the upper and lower anchor ring and setting upright gum cover 7.Wherein, on the clip 15 with interior heavy screw 18, upper and lower joint (1,16) and urceolus 2 cooperation place sabot roots 17.
