Embodiment Construction

[0030] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0031] The invention is composed of a container (1), a ball head cylindrical indenter (4), a jig upper jaw (6), a jig lower jaw (7), a circulating pump (14) and a rock sample (16). Below in conjunction with accompanying drawing, connection mode and effect thereof of each part of the present invention are set forth as follows:

[0032] The container (1) consists of a stainless steel frame and plexiglass plates (2A, 2B), and is used to hold brine. The stainless steel frame is welded by stainless steel plates. After the stainless steel frame of the container (1) is processed, glass glue is applied to the two gaps reserved for the stainless steel frame, and then the plexiglass plates (2A, 2B) are inserted into the gaps where the glass glue is applied. ) to ensure a good seal between the plexiglass plates (2A, 2B) and the stainless steel plate to pr...

Abstract

The invention discloses a rock mechanical test loading device under brine corrosion conditions, comprising a container, a ball-end cylindrical indenter, the upper jaw of a fixture, the lower jaw of the fixture and a circulation pump. Glass cement is applied in two pre-reserved slits on a stainless steel frame, an organic glass plate is inserted into the slits, symmetrical screen sandwich grooves are welded on the container, screens are inserted into the symmetrical screen sandwich grooves, a drain hole on the bottom of the container is sealed by a screw plug and a rubber gasket, a ball valve is connected with the container, and the ball valve on the container is connected with a circulating pump through a transparent plastic hose. A rock sample splitting fixture is disposed in the container and consists of the arc-shaped upper jaw and the arc-shaped lower jaw of the fixture, and the upper jaw of the fixture is connected with the ball-end cylindrical indenter. The invention has simple structure and convenient operation, and can simulate the actual operating condition that brine and a flow field cooperatively act on a dissolution cavity in the cavity creating process of gas (oil) storage, thus obtaining more actual and reliable parameters detected by indoor test.

Description

technical field [0001] The invention relates to the technical field of rock mechanics and engineering tests, and more specifically relates to a rock mechanics test loading device under the coupled action of a physical flow field and a chemical corrosion field. It is suitable for testing the tensile strength of rock under the condition of stable flow field erosion, especially suitable for testing the tensile strength of mudstone and salt rock in the process of brine flow field erosion. Background technique [0002] In the water-solution cavity building process of deep underground salt rock karst cavity gas storage (oil) storage, the insoluble interlayer of the cavity is mainly mudstone, and the surrounding rock of the cavity is mainly composed of mudstone and salt rock. Studies have shown that the influence of water on the mechanical properties of these two rocks is very obvious. [0003] Therefore, in the process of indoor test, how to effectively simulate the actual workin...
