Description
Technical field
It breathes freely (water) property coefficient the field of test technology the invention belongs to coal and rock, and in particular to a kind of with diversion function
Seepage flow plate and its test method for cleaning.
Background technique
Measurement coal and rock is breathed freely (water) property coefficient under axis pressure and confining pressure loading environment, is adopted first from needing to measure in coal seam
Coal petrography sample is taken, the cylindric of certain size is made in coal sample with grinding wheel or special drilling pipe in laboratory, both ends polish, and are formed
It is about 80-100 mm, diameter is that the cylinder of 40-60 mm is then placed in the similar fixture of diameter therewith；Then coal and rock is tried
Sample carries out axis pressure and confining pressure load；It is finally passed through gas (or water flow) from the side of coal and rock sample, it is ventilative to carry out coal and rock
(water) property coefficient testing experiment.Under axis pressure and confining pressure loading environment, when carrying out water drive gas and water drive oil two-phase displacement experiment,
Use the mistake enabled flow across inside coal and rock sample from one end Jiang Shui of coal and rock sample, the oil fluids injection such as gentle
Journey.
During previous test, coal and rock test specimen upper and lower ends can each placement columned seepage flow plate of one entire body,
A few circle seepage flow eyelets are along the circumferential direction dispersed on seepage flow plate.Conventional seepage flow plate has following disadvantage: (1) hole intraocularly passes through
It is commonly present cinder or rock particles blocking, needs to use fine needle or thin wire through-hole one by one, cleaning blocking eyelet is very cumbersome, time-consuming
Effort；(2) when eyelet blocking is serious, if if handling not in time the eyelet of blocking, will result in the rust of eyelet
Erosion even blocks, and fluid can not intraocularly be passed through from hole, cannot be reused, directly be scrapped；(3) due to being injected by water, oil, gas
To during coal and rock test specimen, these fluids are with certain pressure.Fluid with pressure can be from coal and rock test specimen
One end flow to the other end along the gap between coal and rock outer circle and fixture (sleeve) inner wall so that measurement result and reality
There are biggish deviations for measurement result.
