摘要： The present invention relates to mixtures of sulfonated thermoplastic polymers and amine-treated clays 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 sulfonated thermoplastic polymers have 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. 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 polymer in the oil drilling mud by decreasing the strong ionic interactions between the sulfonate groups of the sulfonated polymer.

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.

摘要： The present invention relates to a process for the plugging of a porous formation which may be encountered during the drilling of a well. The process entails plugging of the porous formation by means of a polymeric solution containing pseudo-emulsion spheres. These particles penetrate the pore structure within a formation. Eventually, sufficient numbers of the spheres will accumulate within the pores, blocking further flow through the formation by both the pseudo-emulsion particles and any aqueous solutions. The pseudo-emulsion system is formed by a process which includes the steps of forming a solvent system of an organic liquid or oil and a polar cosolvent, the polar cosolvent being less than about 15 weight percent of the solvent system being less than about 100 cps; dissolving a neutralized sulfonated polymer in the solvent system to form a solution, a concentration of the neutralized sulfonated polymer in the solution being about 0.01 to about 0.5 weight percent, a viscosity of the solution being less than about 200 cps; and admixing or contacting said solution with about 5 to about 500 volume percent water, the water being immiscible with the organic liquid and the polar cosolvent and neutralized sulfonated polymer transferring from the organic liquid to the water phase, thereby causing the water phase to gel (i.e., thicken).
