Visible rock core clamp

Abstract

The invention discloses a visible rock core clamp which is designed to realize that a rock core is visible during a rock seepage simulation experiment so as to meet requirements on scientific research and production. The visible rock core clamp mainly comprises a transparent rubber barrel covering the rock core, an adjustment plunger and a stopping plunger which are used for clamping the rock core, a transparent barrel and an outer barrel which are used for sleeving the transparent rubber barrel, an upstream sealing disk and an adjustment sleeve which are used for sleeving the adjustment plunger, a downstream sealing disk for sleeving the stopping plunger, and an upstream pressure cap and a downstream pressure cap which are used for locking the clamp. The visible rock core clamp disclosed by the invention can be applied to the rock core clamping in the rock seepage simulation experiment in the field of petroleum geology; during experiment, a user can directly observe the experiment condition of the rock core through the transparent barrel and the transparent rubber barrel, so that test failures and test data errors which are caused by medium crossflow can be avoided; a photographing device can be used for monitoring the experiment; an ultraviolet light source can be used for irradiating the rock core, so that the fluorescent reaction of petroleum on the surface of the rock core can be observed, and all experiment researches can be implemented.

Description

technical field [0001] The invention relates to a visible rock core holder, which belongs to the technical field of petroleum geology. Background technique [0002] At present, in various laboratories in the oil field, conventional rock core clamping equipment is used to simulate the stress state of the rock in the formation. The simulation equipment uses a metal cylinder to bear pressure, a rubber cylinder to wrap the core and the periphery of the rubber cylinder to apply pressure. The core in the core is completely sealed in the holder and cannot be observed by the naked eye. If the holder is not firm, the medium will flow through the gap between the rubber tube and the core, resulting in test failure or wrong test data. Contents of the invention [0003] The purpose of the present invention is to provide a visual core holder, which can realize naked eye visualization during core seepage simulation experiments, so as to meet the needs of scientific research and producti...
