Embodiment
Below in conjunction with accompanying drawing, the present invention is described in more detail.
To an autoclave mould for Self-expandable packer test, as shown in Figure 1, be made up of Self-expandable packer and autoclave, Self-expandable packer is made up of test specimen base tube 11 and self-expanding rubber 12; Autoclave is made up of oil pipe 1, set collar 3, left end cylinder 4, right-hand member cylinder 14, packer testpieces 5 and disposable sleeve 6; Wherein left end cylinder 4 and right-hand member cylinder 14 are made up of oil pipe mouth 2, wide liner 7, Che Shi sealing ring 8, sleeve pipe pad 9, sealing taper thread 10, and the cylindrical enclosure structure formed with test specimen base tube 11.
Disposable sleeve 6 is connected with left end cylinder 4 and right-hand member cylinder 14 by sealing taper thread 10; During test, the self-expanding rubber 12 on packer testpieces expands in disposable sleeve 6.
Three grades of steps are had in left end cylinder 4 and right-hand member cylinder 14.As shown in Figure 3, first order step 15 has sealing taper thread 10 and is connected with disposable sleeve 6, second level step 16 is oil pocket, oil pocket barrel is opened an oil pipe mouth 2, hydraulic oil injects oil pipe mouth 2 by oil pipe 1, third level step 17 is laid two grooves 13, Che Shi sealings 8 and is combined by " C " type stationary ring and " O " type rubber ring and be separately positioned in two grooves 13, and one end of test specimen base tube 11 is stretched out from third level step end 17; Set collar 3 is connected by the external thread of internal thread with test specimen base tube 11, and set collar 3 has outer-hexagonal, and set collar 3 pairs of autoclaves play secondary and tighten up effect, play axial restraint effect to Self-expandable packer 5 simultaneously; Wide liner 7 is arranged between the end face of set collar 3 and left end cylinder 4 and the end face of right-hand member cylinder 14; Sleeve pipe pad 9 is arranged on left end cylinder 4 and between right-hand member cylinder 14 and disposable sleeve 6 respectively.
Set collar 3 plays fixing left end cylinder 4 and acts on, and can be connected with the bulb of fritillary, flange or welding manner with disposable sleeve 6.Wide liner 7 is between set collar 3 and left end cylinder 4 end face and right-hand member cylinder 14 end face, and its material can be nonmetal, semimetal and metallic gasket.Che Shi sealing ring 8 is laid in two grooves 13 of third level step 17; Except the Che Shi sealing ring that " C " type of employing stationary ring and " O " type rubber ring combine, mechanical sealing, labyrinth sealing, the sealing of filling chock formula can also be used to replace.Sleeve pipe pad 9 is arranged on left end cylinder 4 and between right-hand member cylinder 14 and disposable sleeve 6, can removes sleeve pipe pad 9 and adopt oil sealing, also can replace with fluid sealant; Casing cushion sheet material can be nonmetal, semimetal and metallic gasket.
The specific works process of this autoclave: before experiment, packer testpieces 5 is loaded in disposable sleeve 6, left end cylinder 4 and right-hand member cylinder 14 are connected with disposable sleeve 6 by sealing taper thread 10, and now the two ends of packer testpieces 5 are stretched out respectively from left end cylinder 4 and right-hand member cylinder 14; Two set collars 3 are needed to be fixed on the both sides of left end cylinder 4 and right-hand member cylinder 14 by the screw thread at the two ends (part from left end cylinder 4 and right-hand member cylinder 14 stretch out) of packer testpieces 5; The screw thread finally oil pipe 1 being connected to oil pipe mouth 2 completes the assembly working before test.
When starting to test, hydraulic oil is injected by oil pipe 1, and the self-expanding rubber 12 on packer testpieces 5 is met oil and expanded until be close to completely with disposable sleeve 6; Squeeze into the correlated performance of the test of the hydraulic oil after pressurization packer testpieces 5.
During off-test, successively the set collar 3 at autoclave two ends, oil pipe 1, left end cylinder 4 and right-hand member cylinder 14 are unloaded after hydraulic oil unloading; Disposable sleeve 6 and the packer testpieces 5 be close to wherein are disposable unit.
The invention is not restricted to the above description to embodiment, the content that those skilled in the art disclose according to the present invention, the improvement that basis of the present invention need not be carried out through creative work and amendment, all should within protection scope of the present invention.
