Background technology
Along with the continuous progress of drilling technology, the field of gas drilling application is more and more extensive, but the drilling engineering problem brought therewith also constantly occurs, particularly hole cleaning problem. The circulatory mediator that gas drilling adopts is gas, and the density of gas is far smaller than the density of cutting grain, and when gas injection rate is not enough and can produce the accumulation of landwaste in special borehole segments, the particle packing of different-grain diameter together, forms cutting bed. Cutting bed, once be formed, is just difficult to clean off, and generally adopts the method adding atm number, but adds atm number simply and can wash away the borehole wall and drilling-rod external wall, causes the operating mode such as hole collapse and drilling tool failure to occur. Under identical gas injection rate, the cutting grain percussion to cutting bed, it is more conducive to Cutting Disposal. If the device of a kind of simulation rock granule impact cutting bed therefore can be invented, not only facilitate the principle of research granule impact cutting bed, also have important meaning for improving gas drilling effect of hole cleaning.
