Description

A device for measuring rock permeability anisotropy

technical field

The utility model relates to the geological field of oil fields and mining areas, in particular to a rock permeability anisotropy measuring device.

Background technique

In the process of geological core observation in oil fields and mining areas, no matter in the process of core sampling, core observation or rock experiment, it is often necessary to measure the anisotropy of rock permeability. Traditional rock core permeability measurement devices often realize the measurement of small rock samples or complete rock cores, and the measured results are often the permeability in a certain direction or several directions. When there are micro-cracks and large-scale cracks in the rock sample, the measurement is difficult. ; and traditional methods are often at a loss when measuring permeability in different directions.

Utility model content

The utility model aims to solve the above problems, and provides a rock permeability anisotropy measuring device, which overcomes the problem that the traditional method cannot easily and accurately measure the rock permeability anisotropy, and the technical scheme adopted is as follows:

A device for measuring rock permeability anisotropy, comprising a seepage tube, a flow meter, a diversion tube, a protective case, a switch valve and a diversion hole; the rock sample to be measured is located in the protective case, and the seepage guide tube and The flow meter is fixed on the protective shell at equal intervals; the fluid in the seepage tube flows out through the diversion hole; the switch valve is screwed to the bottom of the seepage tube.

On the basis of the above technical scheme, a small hole vertical to the rock sample is drilled in the middle of the rock sample, and the seepage pipe passes through the small hole in the middle of the rock sample.

The utility model has the following advantages: reasonable design, convenient and accurate measurement of rock permeability anisotropy, strong operability, and convenient portability.

Accompanying drawing is the three-dimensional schematic view of the utility model;

In the accompanying drawings, 1. seepage pipe, 2. flow meter, 3. diversion pipe, 4. protective shell, 5. switch valve, 6. diversion hole, 7. rock sample.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in the accompanying drawings, a rock permeability anisotropy measuring device includes a seepage tube 1, a flow meter 2, a diversion tube 3, a protective case 4, a switch valve 5 and a diversion hole 6; the measured rock sample 7 is located in In the protective case 4, the flow guide pipe 3 is connected to the seepage pipe 1; the flow meter 2 is fixed on the protective case 4 at equal intervals; the fluid in the seepage pipe 1 flows out through the flow guide hole 6; The on-off valve 5 is screwed to the bottom of the percolation tube 1 to close the percolation tube 1 .

Preferably, the middle part of the rock sample 7 drills a small hole vertical to the rock sample 7, the seepage pipe 1 passes through the small hole in the middle of the rock sample 7, and is closed by the switch valve 5 at the bottom so that the water in the seepage pipe 1 cannot flow from the bottom. flow out.

When in use, first the middle part of the rock sample 6 is drilled through, the seepage pipe 1 passes through the middle of the rock sample 7, and the bottom is closed with the switch valve 5, and water is introduced into the seepage pipe 1 from the guide pipe 3. The water flows through the rock sample 7 from the flow meters 2 in different directions, and the flow statistics of the flow meters 2 in different directions are used to evaluate the anisotropy of rock permeability.

The utility model has been described above with examples, but the utility model is not limited to the above-mentioned specific embodiments, and any changes or modifications made based on the utility model all belong to the protection scope of the utility model.
