An Investigation on the Function of Mud Cakes on the Inhibition of Low Molecular Inhibitor for Water-Based Drilling Fluids

Abstract: The major low molecular inhibitors showed inhibition in the hydration of clay in the laboratory for water-based drilling fluids, according to the principle of intercalation adsorption. However, inhibitors have failed and caused serious engineering accidents in drilling oil and natural gas. This paper investigated the transmission of several of drilling fluids to indicate whether low molecular inhibitor for drilling can effectively inhibit the wellbore hydration. The inhibition of drilling fluid with the pluggi… Show more

“…The plugging function of drilling fluids has a significant meaning on the stability of the shaft wall. The plugging function can be improved on the whole scale by adding some compound plugging agents when using water-based drilling fluids, which is conducive to ensuring the stability of the shaft wall . The HTHP filtration loss of PF-ECOSEAL with recovered solids as a plugging agent is significantly lower than without a plugging agent (PF-0), which indicates that the addition of recovered solids can improve the HTHP performance of drilling fluids and play a better role in reservoir protection (Figure b).…”
