Shale hydration is the main reason causing wellbore instability in oil and gas drilling operations. In this study, nanoscale laponite as a shale inhibitor was employed to stabilize wellbores. The inhibition property of suspensions evaluated by an immersion experiment, linear swelling measurement, recovery test. Then mechanism studied using capillary suction time (CST) thixotropy plugging performance evaluation, related theoretical analysis. Evaluation experiment results showed that had...
During ultradeep oil and gas drilling, fluid loss reducers are highly important for water-based drilling fluids, while preparing high temperature- salt-resistance with excellent rheology filtration performance remains a challenge. Herein, micro-crosslinked amphoteric hydrophobic association copolymer (i.e., DADC) was synthesized using N,N-dimethyl acrylamide, diallyl dimethyl ammonium chloride, 2-acrylamido-2-methylpropane sulfonic acid, monomer, pentaerythritol triallyl ether crosslinker....
Wellbore instability and formation collapse are crucial issues in the process of well excavation oil industry under extreme salinity high-temperature conditions. This study demonstrates that a salt-responsive zwitterionic polymer brush (NS-DAD) based on modified nanosilica as fluid-loss additive utilizing anti-polyelectrolyte effect water-based drilling fluids (WDFs) to overcome wellbore caused by failure polyelectrolytes at high temperature. Additionally, nonionic (NS-D), an anionic...
Summary The rapidly increasing global oil/gas demand and gradual depletion of shallow reservoirs require the development deep geothermal reservoirs. However, drilling suffers from drilling-fluid failures under ultrahigh temperature, which cause serious accidents such as wellbore collapse, stuck pipe, even blowouts. In this study, we revealed role polymeric additives in improving ultrahigh-temperature tolerance bentonite-based fluids, aiming to provide practical efficient solutions failure...
With increasing global energy consumption, oil/gas drilling has gradually expanded from conventional shallow reservoirs to deep and ultra-deep reservoirs. However, the harsh geological features including high temperature salinity in have become a critical challenge faced by water-based fluids (WDFs), which seriously deteriorate rheology fluid loss properties, causing accidents, such as wellbore instability formation collapse. In this study, novel temperature- salt-resistant micro-crosslinked...
