The operation of the method is simple, and anyone can simulate the effect of the flushing of mud cake downhole and calculate the flushing efficiency in laboratory. Laboratory experiments showed that this device can effectively simulate the flushing process of mud cake downhole and horizontally compare different flushing fluid.Read More
