摘要： Methacrylate derivatives are added to salt-containing media to thicken the media, and are particularly useful in the exploration of mineral oil or natural gas deposits. The salt-containing media have a specific density of 1.2 to 2.5 kg/l. The respective methacrylate derivatives, which may be, e.g., mono- and/or difunctional variants, have been found to be particularly suitable, are used in a volume ratio of 100 to 1:1 and an amount of 0.5 to 15% by volume. The thickening of the salt-containing media is effected primarily as gel formation, which can be carried out with the aid of free radical initiators and at elevated temperatures. In particular, completion brines, drilling and drill-in fluids and fracturing fluids and acids having high salt contents are to be regarded as aqueous media. The methacrylate derivatives have a markedly good solubility in heavy brines, as are used primarily in upstream processes of the oil industry. They can also be polymerized subterraneously, and they simultaneously have a high thermal stability.

摘要： Subject matter of the present invention is a drilling fluid additive based on sulfonated asphalt, which comprises a water soluble and anionic polymer component in quantities of 0.1 to 20 wt. %, with respect to the total additive in addition to the asphalt component. With this additive the water solubility of sulfonated asphalt can be markedly increased. This additive, whose polymer component is thermally highly stable, is utilized primarily in water- and/or oil-based drilling fluids and in particular in the exploration of subterraneous petroleum and natural gas deposits. Typical polymer components to consider are representatives of polycondensation products, such as phenol resins, ketone resins and sulfonated naphthalene, acetone and amino plasticizer resins (for example urea and melamine resins).

摘要： A novel method for breaking the viscosity of an aqueous phase thickened with preferably hydrophilic polymers in the exploration and production of mineral oil and/or natural gas is proposed. For this purpose, the breaking is carried out via the formation of a low-viscosity emulsion, with water as the continuous phase, this emulsion being formed by the addition of at least one surface-active component to a system which consists of the thickened drilling fluid and an oil phase which is crude oil present in the reservoir and/or oil introduced into the reservoir. Solubilizers between oil phase and water phase and in particular non-ionic surfactants, cationic surfactants and/or amphoteric surfactants are used as a preferred surface-active component. In addition to the surface-active component, it is possible to use further components, which are demulsifiers, non-emulsifiers, co-surfactants or surface tension modifiers. With the aid of this method, with the simultaneous presence of an oil phase, the aqueous phase can be displaced as a low-viscosity system and finally discharged at the surface, extremely effective cleaning of the well being associated therewith. With regard to the cost-efficiency and from an environmental point of view, the use of chemicals can be completely dispensed with.
摘要翻译：提出了一种在勘探和生产矿物油和/或天然气中破坏优选亲水聚合物增稠的水相粘度的新方法。为此目的，通过形成低粘度乳液进行断裂，以水为连续相，该乳液通过将至少一种表面活性组分加入到由增稠的钻孔流体和油相，其是存在于储存器中的原油和/或引入储存器的油。油相和水相之间的增溶剂，特别是非离子表面活性剂，阳离子表面活性剂和/或两性表面活性剂被用作优选的表面活性组分。除了表面活性组分之外，还可以使用其它组分，这些组分是破乳剂，非乳化剂，辅助表面活性剂或表面张力调节剂。借助该方法，同时存在油相，水相可以作为低粘度体系移位，最后在表面排出，极其有效地清洗与其相关的井。关于成本效益和从环境的角度来看，化学品的使用可以完全免除。

摘要： A method for the rheology control of fluid phases, in which adducts which contain layered mixed metal hydroxides (MMH) and hectorite are used, and corresponding compositions for this purpose are claimed. Preferably used MMH are those which were produced by hydration of mixed metal oxides or oxyhydroxides, which in turn may be thermally activated. The use of coprecipitated MMH or of MMH produced in situ is also possible. The ratio of MMH to the hectorite component should preferably be from 0.05 to 0.2:1, it also being possible to use adducts whose clay fraction contains up to 80%. by weight of clays differing from hectorite, in particular bentonite. The method is preferably carried out using drilling fluids in the high-temperature range >300° F. (>149° C.).

摘要： The invention relates to a mixture composition having dispersing properties, containing copolymers based on unsaturated mono or dicarboxylic acid derivatives and oxyalkylene ethers as component I and water-soluble copolymers and terpolymers containing sulfo groups having an average molecular weight of 50 000-20 000 000 g/mol as component II. By combining both components, which can be respectively characterized by four different structural units, it is possible to obtain mixture compositions which can, more particularly, be used as dispersing agents for organic and/or inorganic pigments and fillers, in addition to known applications in the field of structural chemistry. In the field of structural chemistry, the mixture compositions are suitable for use on account of the dispersing properties thereof, particularly in ceramic systems and in water-based painting and coating systems. Independently of the dispersing effect thereof, the described mixture compositions are also excellent solvents, wherein they can be used more particularly as casein substitutes, even in self-levelling gap-filling materials and trowelling compounds by virtue of the stabilizing effect thereof. The inventive mixture composition combines known positive properties of components I and II and can be used in new fields of application, even in the non-structural chemistry field.
