The object of the present invention is achieved like this: a kind of simulation current device to reservoir stability rock mass souring under rainfall at sunshine and weathering comprises test cabin and is located at the spiral agitator axle in described test cabin, spiral agitator axle is provided with spiral agitator blade, and rock sample container edge is with test cabin side edge and be communicated with test cabin;
There is sunlight simulator at axle center place, test cabin inwall top.
Further, rock sample container inner wall is provided with sealant.
Further, test cabin inwall end face fixes the perforated water spray of hollow and annular, and perforated water spray is connected with external water supply installation, and perforated water spray surface is provided with water spray hole.
Further, test cabin exterior top surface place is connected with fan blower.
All right, described perforated water spray inside is provided with rotation catch, rotates catch around perforated water spray central rotation.
The invention has the advantages that, this device can consider rock sample height in the speed of current scour rock sample, invasion water, rock sample drying and watering cycle time and number of times, rainfall amount size, sunshine duration and the factor such as temperature separately to the influence and effect effect of rock sample, simulate falling zone that under the actual natural conditions of rainfall at sunshine, weathering current produce the souring of reservoir stability rock mass and fluctuation in stage after also can considering above-mentioned factor to the impact of reservoir stability rock mass.
Simultaneously this device compensate for simulated flow in room conditions to wash away the testing equipment that the falling zone that produces with fluctuation in stage affect reservoir stability rock mass blank, reduces the difficulty studied reservoir stability rock mass.By the fretting wear situation of current scour effect to rock particular surface, thus quantitative research is launched to souring, later stage can carry out CT flaw detection scanning, microcosmic electron-microscope scanning, slice analysis, triaxial compression test etc. to test rock sample, and physical property and the mechanical characteristics of rock are evaluated in further quantitative analysis.
