Abstract
The invention relates to a rock core holder. The rock core holder comprises an end cover and a rock core holder main body, wherein the end cover is connected with the rock core holder main body; stopping plugs are arranged on the left side of the end cover, and adjusting plugs are arranged on the right side; a rubber sleeve is arranged on the inner side of an outer wall of the rock core holder main body, and pressure source joints are arranged on the outer wall; a rock core pad is arranged on the rubber sleeve, and stopping plugs are arranged on both sides of the rubber sleeve; a plurality of annular grooves are respectively formed in the stopping plugs and the adjusting plugs; sealing rings are arranged in the grooves, and anti-corrosion material layers are respectively laid at the right end parts of the stopping plugs and the left end parts of the adjusting plugs; at least two pressure source joints are uniformly distributed on the rock core holder main body. The rock core holder has reasonable design. Through the setting of the anti-corrosion material layers and high-temperature resistant material layers, the surfaces of the plugs can be effectively protected, so that the service life of the core holder is prolonged.
Description
Technical field
The present invention is rock electrical measurement field, particularly relates to a kind of core holding unit.
Background technology
In order to simulate in actual formation burial diagenesis process, the consecutive variations situation of reservoir physical parameter under compaction, utilizing different made ground matter samples, is a kind of main path to the simulated experiment of sandstone Compaction, and wherein core clamping mechanism is requisite parts in experimentation.Existing core holding unit is made up of shell, rubber tube, the left top of rock core, the right top of rock core, left fixed muffle, right fixed muffle, left fastening sleeve, right fastening sleeve and fixed support mostly.Whole clamper and internal part are cylindrical tube, most importantly stressed problem during test, add fluid or gas by entrance mostly owing to testing, core clamping mechanism bears larger acting force, easily core clamping mechanism is caused damage, simultaneously, core clamping mechanism high temperature resistant, corrosion resistance is all poor, thus have impact on the mensuration of experimental index, when core clamping mechanism works, need high temperature and high pressure, therefore requirement is proposed for its sealing, need to carry out careful observation to the compacting process of made ground matter sample in experimentation simultaneously, therefore a kind of uniform force is just needed, high temperature resistant, the core holding unit of corrosion-resistant and good airproof performance.
