At present, need rock sample is sealed in the petrophysics experiment that research saturation affects on Rock Elastic Parameters
Process, and the quality of sealing effectiveness has material impact to the accuracy of measurement and precision.
Existing conventional seal means are rubber sleeve sealing and epoxide-resin glue sealing.Wherein, rubber sleeve sealing will rubber
Gum cover is sheathed on the outer surface of rock core (namely core), but because rock surface has certain roughness, rubber sleeve and rock core
Surface still suffers from partial gap, and when carrying out saturation test, experiment sealing effectiveness is unsatisfactory, and, rock core often needs in height
Tested in warm environment under high pressure, for simulating subsurface reservoir situation, and in high temperature and high pressure environment, the rubber sleeve of sealing rock core
Under the erosion of corrosive gas or fluid long period, it is susceptible to plastic deformation, lead to rock core seal failure, and then lead to
The failure of an experiment.Therefore, epoxide-resin glue is sealed to conventional means, and (for example, low frequency stress strain is real in some experiments
Test) in, epoxide-resin glue sealing is unique means.
Wherein, epoxide-resin glue sealing is the outer surface that epoxide-resin glue is applied in rock core, smears in epoxide-resin glue
During, after core clamping device clamps core sample, by epoxy is smeared to the sample surfaces that are rotated in of core sample
Resin glue, the uniformity coefficient of coating, thickness and epoxide-resin glue penetrate into rock core situation be judge sealing effectiveness fine or not important according to
According to this requires that core clamping device has very high concentricity, and to guarantee coating uniform, and coating is thin and does not affect close
Envelope effect, therefore, suitable core clamping device carries out epoxide-resin glue sealing and plays decisive action to rock core.
The core clamping device being currently used for sealing rock core by epoxide-resin glue is less, and existing core clamping device exists
When keeping rotation rock core concentricity, effect is poor, and then leads to coating became uneven so that under the conditions of equal confined pressure, rock core
Surface stress is different, and then reduces the measuring accuracy of core surface stress-strain state experiment, or even causes to test number
According to distortion, lead to the failure of an experiment.Therefore, exploitation design is a is specially adapted for using epoxide-resin glue, rock core being sealed
Core clamping device, becomes a difficult problem in the urgent need to address at present.
The problem existing in view of above-mentioned prior art, the present inventor combines the design for many years of related manufacture field and use
Experience, is aided with too strong Professional knowledge, provides a kind of core clamping device for sealing rock core, to overcome drawbacks described above.
