摘要： This invention relates to a method for enhanced recovery of petroleum from a subterranean oil-bearing formation. More particularly, this invention relates to secondary or tertiary recovery of oil employing a polymer thickened aqueous drive fluid. The polymeric viscosifier for the drive fluid is selected from a class of hydrophobically associating water soluble polymers containing one or more water soluble monomers and a water insoluble monomer or group. The water soluble groups are acrylamide and a salt of an ethylenically unsaturated sulfonic acid and the water insoluble group is a higher alkyl acrylamide. These polymers, when dissolved in an aqueous brine solution, have the ability to substantially increase the viscosity of the solution. The control of displacement fluid mobility results in more uniform sweep efficiency and improved oil recovery. In addition, aqueous solutions of these hydrophobically associating polymers exhibit enhanced viscosification, reduced salt sensitivity and other desirable rheological properties found useful in chemically enhanced oil recovery processes.
摘要翻译：本发明涉及一种从地下含油地层提高石油回收率的方法。更具体地说，本发明涉及使用聚合物增稠的含水驱动流体的二次或三次回收油。用于驱动流体的聚合物增粘剂选自一类含有一种或多种水溶性单体和水不溶性单体或疏水缔合的水溶性聚合物。水溶性基团是丙烯酰胺和烯键式不饱和磺酸的盐，水不溶性基团是高级烷基丙烯酰胺。当溶解在盐水溶液中时，这些聚合物具有显着增加溶液粘度的能力。位移流体流动的控制导致更均匀的扫描效率和改善的油回收率。此外，这些疏水缔合聚合物的水溶液表现出增强的粘度，降低的盐敏感性和其它在化学强化的油回收方法中有用的所需的流变学性质。

摘要： This invention describes novel hydrophobically associating ter or tetra polymers which can contain sulfonate functionality which are useful as aqueous fluid rheology or flow modifiers. These high molecular weight water soluble polymers contain both water soluble and water insoluble monomers. The water soluble monomers are N, N dimethylacrylamide acrylamide (DMA) and optionally a salt of an ethylenically unsaturated sulfonic acid (s) or N-vinylpyrrolidinone or a metal acrylate and the water insoluble monomer is a higher alkyl acrylamide (R). The process for their preparation relies on solubilizing the water insoluble monomer into an aqueous micellar solution containing one or more surfactants and the water soluble monomers. The surfactants are specifically selected to enable homogeneous dispersion of the hydrophobic monomer(s) in the presence of anionic sulfonate containing monomers. Redox or free radical initiators are used to copolymerize both the water soluble and water insoluble monomers, forming terpolymers of dimethylacrylamide, alkylacrylamides and acrylamide, and optionally an anionic sulfonate or carboxylate monomer. Aqueous solutions of these hydrophobically associating polymers exhibit enhanced viscosification, reduced salt sensitivity and other desirable rheological properties found useful in a variety of applications.

摘要： This invention provides a process for preparing novel hydrophobically associating terpolymers containing cationic functionality which are useful for clean-up of waste waters containing organic contaminants. These water soluble polymers contain both water soluble and water insoluble monomers. The water soluble monomers are acrylamide (AM) and a salt of an unsaturated amine base (C) and the water insoluble monomer is a higher alkyl(meth)acrylamide or alkyl(meth)acrylate (R). These polymers are referred to as CRAM. The process for their preparation relies on solubilizing the water insoluble monomer into an aqueous micellar solution containing one or more surfactants and the water soluble monomers. The surfactants are specifically selected to enable homogeneous dispersion of the hydrophobic monomer(s) in the presence of cationic monomers, such as 3-methacrylamidopropyltrimethylammonium chloride (MAPTAC), 2-methylacrylatoethyltrimethylammonium chloride (METAC), or diallyl dimethylammonium chloride (DMDAAC). Redox or free radical initiators are used to copolymerize both the water soluble and water insoluble monomers forming terpolymers of ethylenically unsaturated amine base salts, alkyl(meth)acrylamides or alkyl(meth)acrylates and acrylamide. These polymers provide exceptional clean-up of waste waters containing organic contaminants. Also, they are very effective for resolving oil-in-water emulsions, such as those found in oil production.
