For the past decades, long-term water flooding processes have led to water channeling in
mature reservoirs, which is a severe problem in oilfields. The development of better plugging …

With increasingly stringent environmental regulations, an environmentally friendly and high
performance filtration loss reducer for water-based drilling fluid is essential. This study aims …

As the number of ultra-deep wells increases, maintaining the suspension stability of cement
slurry at ultra-high temperatures becomes increasingly challenging; the development of a …

Abstract β-cyclodextrin polymer (β-CDP) microspheres were investigated as high
temperature resistant filtration reducers for water-based drilling fluid in this study. The …

With the development of deep and ultra-deep wells, there is a need to enhance the
rheological and filtration properties of water-based drilling fluids under high temperature and …

Aiming at the challenge that environmental protection and high-temperature fluid loss
reduction performance of the traditional water-based drilling fluid treatment agent are difficult …

The purpose of the present work is to enhance the thermal stability and rheological
properties of semi-interpenetrating polymer network (IPN) hydrogel based on partially …

In the paper, nano-silica (nano-SiO2)/Welan gum (RSWG) nanocomposite was synthesized
as thickener to improve the sedimentation stability of high-temperature drilling fluid …

One of the key challenges preventing the exploration and development of ultra-deep oil and
gas deposits is the settlement instability of cement slurry at extremely high temperatures. In …

As exploration and development continue to expand, the number of high-temperature deep
wells is on the rise. However, the instability of high-temperature cement slurry remains a …
