The utility model belongs to the technical field of the oil recovery engineering, concretely relates to to grinding testing experiment device under ambient condition, the internal part of seal box is the test region at middle part and heating region, the control area that lies in regional its both sides of test, and the last surface mounting of sealed box has pressure regulator, and sealed box still feeds through to pressure device through the pipeline. Under simulation different temperatures, different pressure (being the well depth scope) condition, in the moisture scope crude oil medium of difference, carry out different materials and right the piece to grinding the experiment, the simulation tests of can pressurizeing simultaneously, this kind of to grinding testing experiment device under ambient condition and method have realized the condition of production of simulation oil well under high temperature (0-90 degree), high pressure (0-25MPa) condition, the different moisture condition (0-100%) of simulation oil well can be mixed through crude oil and clear water with certain proportion, can satisfy the wearing and tearing test (0-40 kilogram force) that big inclined shaft section received the yawing force, through with known set upright or straight abrasionproof block of material to grinding the experiment, can accurately know the performance of the material that awaits measuring, divide and appear it and whether adapt to corresponding borehole operation environment.
