Experimental investigation of cuttings transport with nanocomposite water-based drilling fluids modified by cellulose nanoparticles

摘要: Abstract Extended reach (ERD) wells with a horizontal and highly deviated section are commonly utilized in deep oil natural gas exploration operations. Among many difficulties faced this complex wellbore trajectory, good hole cleaning is one of the biggest challenges. The main objective present study to investigate application cellulose nanoparticles (CNPs) improving drilling Nanocomposite fluids were prepared by adding CNPs, including nanocrystals (CNCs) nanofibers (CNFs), into water-based mud (WBM) at different weight percent concentrations (0.15–0.60 wt%). flow loop experiments implemented on sophisticated purpose-built rig circulating tested fluid samples test position, considering influence drill pipe rotation, rates, cuttings sizes, eccentricity. goal such variation operational parameters simulate real field conditions. transport ratio (CTR) which defined as recovered injected chosen measurement evaluate cleaning. results revealed that nanocomposite displayed considerable enhancement removal efficiency, especially higher concentration CNPs. morphology CNPs played vital role rheological properties fluids. In comparison, CNCs had comparatively lower transports than these CNFs. These differences connected their distinguished morphologies interactions bentonite system. This work first attempt applications renewable, biodegradable, environmentally friendly, more cost-effective nanoparticle additives enhance capability transporting drilled out wellbore.
