Oil drilling grade HEC

Short Description:

Hydroxyethyl cellulose is widely used as a thickener and loss control agent in oil drilling. In oil drilling industry, high-viscosity HEC is mainly used as thickener in completion and finishing fluid; while low-viscosity HEC is mainly used as water loss controller. HEC used as thickener will impart good mobility and stability to various slurries necessary for drilling, completion, cementing and fracturing operations.   【Introduction】 Name: Hydroxyethyl cellulose Abbreviation: HEC Molec...

    Introduction

    Name: Hydroxyethyl cellulose

    Abbreviation: HEC

    Molecular formula: [C6H7O2(OH)3-x〖OCH(OH)CH3〗x]n

    Characteristics:

    Hydroxyethyl cellulose (HEC) is a non-ionic, water-soluble polymer derived from cellulose through a series of chemical and physical processes.

    HEC is a white to light yellowish, oderless and tastless powder, readily soluble in hot or cold water to form a viscous gel solution. When pH in solution is within 2 to 12, the solution is quite stable. Since HEC group is nonionic one in water solution, it won’t be reacted with other anions or cations and insensitive to the salts. HEC also has good film-forming ability and surface activity.

    3.Applications

    In oil drilling industry, high-viscosity HEC is mainly used as thickener in completion and finishing fluid; while low-viscosity HEC is mainly used as water loss controller. HEC used as thickener will impart good mobility and stability to various slurries necessary for drilling, completion, cementing and fracturing operations.

    In drilling, HEC can increase the sand carrying capability of slurry and extend the service life of drill bits.

    In low-solid content completion fluid and cementing fluid, the excellent water loss control performance of HEC can prevent large amount of water in the slurry from entering into the oil reservoir, thus increasing the reservoir production capability.


    4.Packaging

    HEC Product is packed in an inner polyethylene bag reinforced with a 3-ply paper bag, or paper barrel or paper box, net weight is 25kg per bag.

    5.Transportation and Storage
