Core clamping system

Abstract

The invention discloses a core clamping system which comprises a sleeve, an adjusting plug group, a heating assembly sleevedoutside the sleeve and a heat preservation assembly sleeved outside the heating assembly, wherein a hollow cavity capable of accommodating a core is formed in the sleeve; the adjusting plug group comprises a plurality of adjusting plugs; the plurality of adjusting plugs are provided with grooves with different diameters; any adjusting plug is detachably connected with the sleeve; and when the adjusting plugs are arranged on the sleeve, one end, with the groove, of each adjusting plug can be inserted into the sleeve and is propped against the core. An operator can select the matched adjusting plug in the adjusting plug group according to the diameter of the to-be-clamped core before clamping the core, and the diameter of the groove of the adjusting plug can be matched with that of the end part of the core, so that the end part of the core can be clamped into the groove, the condition that the core can be stably clamped by the core clamping system is ensured, and the core is prevented from displacing or loosening after being clamped.

Description

[0001] Cross Reference Related References [0002] This application claims the priority of the Chinese patent application with application number "2016108651029" and titled "Core Clamping System" filed on September 29, 2016, which is incorporated herein by reference. technical field [0003] The invention relates to the field of geological exploration, in particular to a rock core clamping system. Background technique [0004] In the fields of petroleum development and geological exploration, the laboratory needs to use the core holding system to hold the core drilled from the formation in the area to be studied. In the prior art, the specifications of the core clamping system include standard sizes such as 25mm, 38mm and 100mm. However, in the actual coring process, due to reasons such as equipment or personnel operation, the cores drilled in the formation may not fully meet the standard size of the core clamping system in the prior art. The diameter of the core may be l...

Problems solved by technology

[0005] In addition, when the rock core is tested or studied, it is necessary to place the rock core under the high temperature conditions of the simulated formation, which requires that the holder for holding the rock core can be placed in a constant temperature device, but the core holding system of the prior art Larger size makes it difficult to place it in a thermostat
