Problems solved by technology

In the existing petrophysical experiments, it is generally considered that the laminar bedding of rock samples is horizontal, but in reality there are two types of non-horizontal bedding: one is that the rock changes in level, which is not strictly The second is that even if the formation section with a small thickness can be regarded as a layered distribution, there is still a certain dip angle, especially when encountering high and steep fo

Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0045] The technical parameters of a rock anisotropy measuring holder provided by the present invention are:

[0046] Rock sample length: 25~200mm, rock sample diameter: 25~50mm, pressure: 0~5MPa,

[0047] In this embodiment, a rock with a length of 50 mm and a diameter of 30 mm is selected as the measurement object to specifically illustrate the use and measurement method of the present invention.

[0048] Such as Figure 1-4 The rock anisotropy measuring holder shown includes a guide rail 2 arranged on a base 1, sliders 3 are respectively arranged at both ends of the guide rail 2, and a propulsion part is arranged on the slider 3 at one end 4. A fixing part 5 is provided on the slider 3 at the other end, and the feature is that the propulsion part 4 includes a first support block 4.1 arranged on the upper surface of the slider 3 at one end and a han...

Abstract

The invention relates to the technical field of experimental devices for rock physical experiments and provides a rock anisotropy measuring clamp and a measuring method thereof. The rock anisotropy measuring clamp mainly comprises a base, a guide rail, a slider, a propelling portion, a fixing portion, a piezometer and an acoustic wave receiving device, an angle adjusting device and an angle pointer are arranged on the propelling portion, and displacement scale marks are formed on the base. The rock anisotropy measuring clamp can measure acoustic wave anisotropy features of a rock core from different angles, and physical response of rock in actual strata can be reflected really, which has guidance effect on exploiting oil-gas reservoirs.

Description

technical field [0001] The invention relates to the technical field of experimental devices for rock physics experiments, in particular to a rock anisotropy measurement holder capable of realizing acoustic waves and resistivity measurements of rock samples under quantitative angle changes. The device can be used to carry out rock resistivity , Measurement and research of acoustic anisotropy experiments. Background technique [0002] In the field of geophysics and rock physics research, it is generally believed that the actual strata are deposited in layers. In the process of oil and gas exploration, it is often necessary to use various physical characteristic responses of rocks to determine the sedimentary ages of strata, and to clarify oil and gas enrichment blocks and depths to guide the development of oil and gas reservoirs. In the existing petrophysical experiments, it is generally considered that the laminar bedding of rock samples is horizontal, but in reality there a...
