安徽Potassium sulfonated asphalt

Performance characteristics of potassium sulfonated asphalt

① it has good water dispersibility, without coalescence and floating

② it has excellent shale blocking property. The asphalt insoluble matter dispersed in the drilling fluid can not only be adsorbed on the surface of shale to form a thin, tough and low permeability hydrophobic oil film, but also can block the formation pores and micro cracks under the pressure difference to reduce the amount of filtrate invading the formation. The cation group has a good blocking effect. Therefore, the product can effectively prevent the hydration expansion of shale and prevent the peeling and collapse of shale, Stable borehole wall

③ it has good plugging effect and can improve the plugging effect when combined with other plugging agents

④ it has a good role in protecting oil and gas reservoirs

⑤ no viscosity increase, especially suitable for preparing drilling and completion fluid with good density

⑥ good thermal stability (& amp; gt; 220 ℃), which can be used to prepare high-temperature deep well drilling and completion fluid

⑦ it has good salt and calcium resistance and can be used for various drilling and completion fluids such as fresh water, brine, seawater and saturated brine

⑧ it has good compatibility with other treatment agents, and can be directly added to various drilling and completion fluids with an addition of 1% - 3%
