【摘要】：目前國(guó)內(nèi)三維滲透率測(cè)試研究處于起步階段,利用自主研發(fā)的煤樣三維滲透率測(cè)試儀,可以模擬實(shí)現(xiàn)真實(shí)三向應(yīng)力狀態(tài)下流體通過(guò)立方體煤樣孔隙的三維滲流,并進(jìn)行真實(shí)三向應(yīng)力條件下煤樣滲透率應(yīng)力敏感性試驗(yàn)研究。試驗(yàn)結(jié)果表明,真實(shí)三向應(yīng)力作用下煤樣水平最大主應(yīng)力對(duì)煤樣水平方向滲透性的影響程度大于水平最小主應(yīng)力;煤樣三維滲透率對(duì)三向應(yīng)力的敏感程度不同,對(duì)垂直應(yīng)力的敏感性最強(qiáng),水平最大主應(yīng)力次之,水平最小主應(yīng)力最小。
[Abstract]:At present, the research of three-dimensional permeability measurement in China is in the initial stage. Using the self-developed three-dimensional permeability tester of coal sample, the three-dimensional seepage through cubic coal sample pore can be simulated under the condition of true three-direction stress. The experimental study on permeability stress sensitivity of coal samples under the condition of true triaxial stress is carried out. The effect of the maximum principal stress on the horizontal permeability of coal samples is greater than that of the minimum horizontal principal stress under the action of true triaxial stress. The three dimensional permeability of coal samples is sensitive to three dimensional stress, the sensitivity to vertical stress is the strongest, the horizontal maximum principal stress is the second, and the horizontal minimum principal stress is the least.
