Hard glucan oilfield field

Hard glucan is used as a thickener for drilling mud; Hard glucan is used as an additive in well completion and repair fluids, which can effectively prevent wellbore collapse and invasion of formation fluids, and play a role in protecting oil and gas reservoirs. Chitosan has stable performance in high-temperature and high salt reservoir environments, and can be used in combination with chemical agents such as oil displacement agents to improve oil recovery

  • Hard glucan is used as a thickener for drilling mud;   

    Hard glucan is used as an additive in well completion and repair fluids, which can effectively prevent wellbore collapse and invasion of formation fluids, and play a role in protecting oil and gas reservoirs.

    Chitosan has stable performance in high-temperature and high salt reservoir environments, and can be used in combination with chemical agents such as oil displacement agents to improve the sweep efficiency of oil displacement agents and increase the recovery rate of crude oil

    Adding hard pectin to emulsified asphalt can improve its stability and viscosity, making it more suitable for use in oilfield road paving, well site construction, and other areas, improving road performance and extending its service life

    The above results indicate that the PS-01 aqueous solution system of hard pectin has good stability to temperature; And with the continuous loss of water, the viscosity of the system continues to increase.
