Product Parameters

Parameters of confining pressure core gripper

Suitable for core samples with a diameter of 1 'and a height of 3/4'~2 ', as well as a diameter of 1.5' and a height of 3/4 '~3';

◆ It can increase the confining pressure of the core and provide high-pressure testing gas and constant temperature environment;

The range of confining pressure is 0-60MPa;

Test gas pressure range from 0 to 20MPa;

◆ Constant temperature range [-10 ℃~+80 ℃], accuracy ± 0.1 ℃;

◆ Equipped with a temperature sensor inside, it can collect the internal temperature of the gripper with an accuracy of ± 0.1%;

Equipped with an exhaust valve, it can remove the air inside before confining pressure is applied;

◆ Provide rubber sleeves for core samples of different sizes;

Core samples with diameters of 1 'and 1.5' only need to replace the plug, making it easy to disassemble and replace.

+Axial compression (optional) core clamp parameters

The 1 'core gripper is suitable for core samples with a diameter of 1' and a height of 3/4 'to 2'; (Can be designed according to the actual situation of the user) Optional

The 1.5 'core gripper is suitable for core samples with a diameter of 1.5' and a height of 3/4 'to 3'; (Can be designed according to the actual situation of the user) Optional

◆ It can increase axial pressure and confining pressure on the core and provide high-pressure testing gas and constant temperature environment;

◆ Axial compression andConfining pressurePressure range 0~60MPa;

Test gas pressure range from 0 to 20MPa;

The constant temperature range is from room temperature+5 ℃ to+40 ℃, with an accuracy of ± 0.1 ℃. The core gripper and testing pipeline are located in the same constant temperature chamber, avoiding errors caused by temperature differences;

◆ Equipped with a temperature sensor inside, it can collect the internal temperature of the gripper with an accuracy of ± 0.1%;

◆ Equipped with an exhaust valve, it can remove the air inside before confining pressure is applied;

◆ Provide rubber sleeves for core samples of different sizes;

◆ Replacement of multiple core clamps, suitable for quick disassembly joints, easy to replace. High pressure gas boosting system

No need for manual pressurization, simply adjust the driving gas pressure to achieve automatic pressure boosting;

Provide a test gas pressure of 0-20MPa to the rock core;

◆ Gas with a pressure not less than 1.5MPa can be pressurized to 20MPa;

Test Report

Penetration measurement range: 1 × 10-10~1 × 10 3 mD

Porosity testing range: 0%~80%

◆ Pore volume, skeleton volume

◆ True density

Test the pneumatic system

◆ All stainless steel pneumatic structure, tested with 30MPa water pressure;

Configure 2 high-precision pressure sensors with a range of 0-200 bar and an accuracy of 0.1%;

The upstream and downstream cavities of the rock core can achieve a very small cavity of 5ml, improving the accuracy of low-permeability rock samples;

According to the type of rock sample used by the user, the number of expansion cavities can be increased to expand the upstream and downstream cavities of the rock sample, thereby improving the accuracy of testing medium and high permeability rock samples; Optional

The valve adopts a fully imported 316 stainless steel high-pressure pneumatic diaphragm valve with high safety and high pressure resistance, which can achieve automatic on-off control within a pressure range of 20MPa, achieve zero leakage sealing performance, and have a service life of up to 5 million times;

The entire gas circuit is checked using a Swiss Infcon helium mass spectrometer leak detector, ensuring sufficient airtightness of the instrument.

Vacuum system (optional)

The sample can be subjected to vacuum treatment;

Select imported vacuum pump with a maximum vacuum degree of 1 * 10-7MPa.

Software features

The software automatically collects and records pressure and temperature values within the system, and draws pressure time and temperature time curves;

Automatically save relevant raw data and calculate results such as permeability, porosity, pore volume, skeleton volume, true density, etc
