    摘要: The present invention relates to sulfonated thermoplastic terpolymers which are terpolymers of t-butyl styrene, styrene and sodium styrene sulfonate wherein these sulfonated terpolymers function as viscosification agents when added to oil-based drilling muds which are the fluids used to maintain pressure, cool drill bits and lift cuttings from the holes in the drilling operation for oil and gas wells. The sulfonated thermoplastic terpolymer of the latex have about 5 to 100 meg. of sulfonate groups per 100 grams of the sulfonated thermoplastic terpolymer, wherein the sulfonated groups are neutralized with a metallic cation or an amine or ammonium counterion. A polar cosolvent can optionally be added to the mixture of oil drilling mud and sulfonated thermoplastic polymer, wherein the polar cosolvent increases the solubility of the sulfonated thermoplastic terpolymer in the oil drilling mud by decreasing the strong ionic interactions between the sulfonate groups of the sulfonated polymer.The drilling muds formed from these latices of the sulfonated thermoplastic terpolymers exhibits markedly improved low and high temperature rheological properties as compared to drilling muds formed from sulfonated thermoplasitc copolymers.

    摘要: The present invention relates to improved viscosification agents for a variety of aqueous solutions which comprise a family of intramolecular polymeric complexes (i.e., polyampholytes) which are terpolymers of acrylamide/metal styrene sulfonate/methacrylamidopropyltrimethylammonium chloride (MAPTAC).The metal styrene sulfonate is an anionic monomer, while MAPTAC is cationically charged. These acrylamide-based polyampholytes have approximately 1 to about 50 mol % of the anionic monomer and approximately 1 to about 50 mole % of the cationic moiety present within the macromolecular structure. These groups are not necessarily present in an equimolar charge ratio. The excess undissociated charge allows for facile dispensability or solubility of the polyampholytes into fresh water.

    摘要: The present invention relates to powdered sulfonated thermoplastic polymers which function as viscosification agents when added to oil-based drilling muds which are the fluids used to maintain pressure, cool drill bits and lift cuttings from the holes in the drilling operation for oil and gas wells. The powdered sulfonated thermoplastic polymer has about 5 to about 100 meq. of sulfonate groups per 100 grams of the sulfonated thermoplastic polymer, wherein the sulfonated groups are neutralized with a metallic cation or an amine or ammonium counterion. The powdered sulfonated thermoplastic polymers have a particle size range of 0.25 .mu.m to 2.5 .mu.m and are prepared by spray drying an emulsion of the sulfonated thermoplastic polymer which has been prepared by a free radical copolymerization process. A polar cosolvent can optionally be added to the mixture of oil drilling mud and sulfonated polymer, wherein the polar cosolvent increases the solubility of the sulfonated polymer in the oil drilling mud by decreasing the strong ionic interactions between the sulfonate groups of the sulfonated polymer.
