Parr Tri-Axial Core Holder

官方英文资料：A1000G / A1300G Tri-Axial Core Holder

官方英文资料：In the oil and gas industry it is common practice to take one or more cylindrical core samples of hydrocarbon containing or other formation and to subsequently perform one or more tests with this core sample in a laboratory. During these tests the core sample is contained within a polymeric sleeve inside a pressurized sample holder assembly known as a core holder. The operating temperature and pressure conditions are substantially similar to the hydrocarbon containing or other formation from which the sample has been taken. A treating, completion and/or stimulation fluid is injected into the sample to determine an optimum composition of the treating, completion and/or stimulation fluid and/or an optimum injection regime.

官方英文资料：Core holders are used to facilitate a variety of studies, including gas and liquid permeability, formation damage, porosity, carbon dioxide capture and storage (CCS), relative permeability, secondary water flooding, enhanced oil recovery and steam flooding.

官方英文资料：A tri-axial type core holder is one where the axial force on the core sample and radial pressure on the sleeve are independent of each other and can be varied during the test. This arrangement is useful in studying the physical characteristics of the core under various conditions. Radial confining pressure is applied through the body wall, along the outer diameter of the sleeved core sample. The axial ram floats against the rock as axial pressure is applied through the end piece and the rock compresses. A specially designed spider web type groove pattern is utilized on the end faces of the core holder’s distribution plugs which come in contact with end faces of the core sample. This is to ensure that the fluids, before entering or on exiting the core-sample, are evenly distributed on the whole face of the core-sample.

官方英文资料：With this design, the core holder does not need to be completely disassembled in order to interchange core test samples. After the confining pressure has been released the retainer and distribution plugs are removed and the core sample is easily removed from the sleeve. The sleeve and end caps remain in place in the core holder. Spacers are provided to accommodate shorter cores. The distribution plugs on either end of the core holder are provided with a single inlet / outlet.

官方英文资料：Parr can provide a complete hydrothermal core flooding system which typically includes the following components.
