Indoor Experimental Study on Water-based Flushing Fluid for Cementing
In well cementing,reasonable design and use of flushing fluid can improve the bonding strength between cement slurry and formation bonding surface by cleaning the wellbore and flushing rock debris through flushing fluid.Based on this,experiments were conducted to evaluate the cleaning effectiveness and compatibility of three different types of flushing fluids for a water-based drilling fluid system applied on-site in a certain sea area in China.The experimental results show that A-type flushing fluid has the best flushing effect on drilling fluid mud cake,the highest bonding strength,and can effectively improve cementing quality.
