Study on the influence of drilling fluid filtration on stability of coalbed wellbore
Coal rock has many porous characteristics, such as cleavage, pore and so on. Drilling fluid is easy to invade into coal bed rock, which is easy to cause wellbore instability. Considering the physical effect of drilling fluid loss on coal rock, a fluid-solid coupling model for evaluating the stabili...
