摘要： Reaction products of polymeric alkyl phenol formaldehyde resins are useful as additives to inhibit or prevent the deposition or precipitation of asphaltenes in hydrocarbon fluids, particularly crude oil produced from a subterranean formation. These reaction products are formed by reacting a polymeric alkyl phenol formaldehyde resin with a co-reactant having functional groups including, but not necessarily limited to, amines, esters, silanes, ketones, epoxides, alkoxides, aryloxides, halogens, alkali metals, alkali earth metals, acetamides, non-metal oxides, metal oxides, where the co-reactant optionally has a carbon chain length between 1 and 22 and the reaction is conducted in the presence of at least one of various solvents. In one non-limiting embodiment, the co-reactant is a silicon derivative. The asphaltene inhibitors have utility when injected into a subterranean formation while oil production temporarily halts, a process called “squeezing,” because they are retained to a degree in the formation as the crude oil is produced.

摘要翻译： 聚合烷基酚甲醛树脂的反应产物可用作抑制或防止沥青质沉积或沉淀在烃类流体中，特别是从地下地层产生的原油中的添加剂。 这些反应产物通过聚合烷基酚甲醛树脂与具有官能团的共反应物反应形成，所述共反应物包括但不限于胺，酯，硅烷，酮，环氧化物，醇盐，芳氧化物，卤素，碱金属，碱土 金属，乙酰胺，非金属氧化物，金属氧化物，其中共反应物任选具有1至22的碳链长度，并且反应在至少一种各种溶剂的存在下进行。 在一个非限制性实施方案中，共反应物是硅衍生物。 沥青质抑制剂在注入地下地层时具有实用性，而油生产暂时停止，这一过程称为“挤压”，因为它们在原油生产时被保留在地层中。

摘要： Generating heat within a combination solvent/acid system removes undesirable deposits from petroleum reservoir formations (especially the near well-bore region), oilfield equipment, and petroleum processing equipment. An exothermic reaction occurs between the solvent and the acid and the heat evolved helps remove organic solid deposits. The acids may include organic acid compounds, such as sulfonic acids, sulfuric acid and nitric acid. The solvents may include terpene- and terpene-derivative-containing solvents, including, but not necessarily limited to, limonene, pinene, dipentene, myrcene, turpentines and compounds having at least one double bond, such as methyl furan, dienes, styrene, vinyl acetate and the like. The exothermic reaction produces a great amount of heat, and together with using certain acids and solvents already known as effective to remove paraffin and asphaltene deposition, removing such deposits is improved.

摘要： A drag reducing additive for heavy oil, such as crude oil, includes a polymeric alkyl-substituted phenol formaldehyde resin and a solvent having at least one of an ester (e.g. ethyl acetate), an aldehyde (e.g. butyraldehyde), and an aromatic hydrocarbon (e.g. toluene, xylene, and the like), or mixtures thereof. When used together with a diluent (e.g. condensate, naphtha, or the like), the additive may reduce viscosity of the combined oil, diluent, and additive by at least 20%, increase throughput by at least 6%, reduce power consumption by at least 3%, reduce the diluent proportion by at least 3%, or some combination of these effects, as compared with an otherwise identical heavy oil without the additive.

摘要： Naphthenic acid solids and/or emulsions can be inhibited by introducing an additive to crude oil prior to or concurrent with the deprotonation of the naphthenic acids present in the crude oil. The additives may be surfactants and can be amines, quaternary ammonium compounds, quaternary phosphonium compounds, and mixtures of both. The additives may also be linear compounds having at least two carboxylic acid or acrylic acid functional moieties.
