Oil Drilling Enhanced Oil Recovery Polyacrylamide

Product Information

        Polyacrylamide (PAM for short) is a commonly used artificial flocculant. It is easily soluble in water and easily decomposed when the temperature exceeds 120°C. The product has properties such as flocculation, thickening, shearing, drag reduction, and dispersibility. The solid is white or slightly yellow powder, the liquid is colorless and viscous, and the colloidal product is colorless and transparent. Anionic, cationic, nonionic, and zwitterionic polyacrylamide can be obtained by chemical modification.

       The homopolymer formed by the polymerization of a single acrylamide is nonionic, and its molecules are not charged. The copolymer formed by the copolymerization of acrylamide and anionic monomers (such as sodium acrylate) is anionic, and its molecules are negatively charged. For the same reason, the copolymer generated by acrylamide and cationic monomers is cationic, and its molecules are positively charged.

      The copolymer contains some ionic monomers, which shows partial ionic characteristics. We use the percentage of ionicity to express the charge on the polymer molecular chain. The higher the ionicity, the more charged the molecular chain is. In this way, the ionicity of nonionic polyacrylamide is zero. What charge (i.e. ionicity) and how much charge (i.e. ionicity) the polyacrylamide molecular chain carries are important considerations when selecting polyacrylamide flocculants.

        Polyacrylamide is a synthetic polymer with a relatively high molecular weight. The molecular weight of polyacrylamide always refers to the average molecular weight, which indicates the average length of each polymer molecule. The larger the molecular weight, the more chain segments each molecule contains, or the longer the average length of each molecule. From the perspective of molecular weight, the flocculation effect of polyacrylamide is not only related to the molecular weight, but also to the molecular structure (straight chain, branched chain, cross-linked) and molecular weight distribution (wide, narrow).

Product Category

         It  is widely used in oil exploration, profile control, plugging agent, fracturing fluids ,drilling fluids  additives.   
        Also plays an important role in these applications for dropping drilling fluid loss, flocculation, dilution, plugging, shale inhibition,  cooling and lubricating the drill bit and drill string, carrying debris, cementing well.

        Can meet all the complex requirements of viscosity, temperature, salinity and flooding performance for oil exploitation

       The company can customize different types of polymers according to different location conditions (ground temperature, salinity, permeability, oil viscosity) and other indicators of each block of the oilfield, so as to effectively improve oil recovery rate and reduce water content.  

Common models are as follows:

Application:

Oil Extraction,Enhanced Oil Recovery(EOR) Polyacrylamide:

        Oil displacement agent refers to the injection of oil from the injection well of the oil field into the underground oil layer in order to improve the recovery rate of crude oil. Oil displacement agent is not injected in primary oil recovery. Secondary oil recovery is characterized by the injection of water and gas (general fluid), and the injected water and gas belong to the oil displacement agent. Tertiary oil recovery is characterized by the injection of special fluids. Different special fluids constitute different oil displacement methods, and different oil displacement methods use different oil displacement agents.

     At present, tertiary oil recovery mainly uses polymer oil displacement technology, which is an economical and effective method to improve crude oil recovery. It can improve crude oil recovery by increasing the sweep coefficient of water, and can also improve the microscopic oil displacement efficiency of the core through the viscoelasticity of the polymer solution. When the geological conditions of the reservoir are certain, the effect of polymer oil displacement mainly depends on the performance of the water-soluble polymer used for oil displacement, which is mainly partially hydrolyzed polyacrylamide (HPAM) and its modified polymers. Through copolymerization, chain links with rings are introduced into the structure to improve the temperature resistance.
