    • An aqueous, viscoelastic fluid gelled with a viscoelastic surfactant (VES) is inhibited against hydrate formation with an effective amount of an additive that could be one or more halide salts of alkali metals and alkali earth metals, formate salts, alcohols, glycols, glycol amines, sugars, sugar alcohols, amidoamine oxides, polymers such as polyamines, polyvinylpyrrolidones and derivatives thereof, polyvinyl alcohols and derivatives thereof, polycaprolactams and derivatives thereof, hydroxyethylcellulose, and mixtures thereof. These fluids are inhibited against hydrate formation and may have increased viscosity as well. The additives may increase viscosity to the point where less VES is required to maintain a given viscosity. These inhibited, aqueous, viscoelastic fluids may be used as treatment fluids for subterranean hydrocarbon formations, such as in stimulation treatments, e.g. hydraulic fracturing fluids.
    • 用粘弹性表面活性剂(VES)凝胶化的水性粘弹性流体用有效量的添加剂抑制水合物形成,所述添加剂可以是碱金属和碱土金属,甲酸盐,醇,二醇,乙二胺的一种或多种卤化物盐 糖,糖醇,酰胺胺氧化物,聚胺如聚胺,聚乙烯吡咯烷酮及其衍生物,聚乙烯醇及其衍生物,聚己内酰胺及其衍生物,羟乙基纤维素及其混合物。 这些流体被抑制以形成水合物,并且粘度也可以增加。 这些添加剂可能会增加粘度以维持给定粘度所需的较少VES。 这些被抑制的含水粘弹性流体可以用作地下烃地层的处理流体,例如在刺激处理中。 水力压裂液。

    • An oil-based fluid system has been discovered using a distribution of salt particle sizes, an oil or water/oil emulsion, a suspending agent for suspending the salt particles in the oil and a filtration control agent. It is important that the salt particles be distributed across a wide size range to effectively prevent filtration or fluid loss into the formation. Since the filter cake particles do not invade the well bore, no high pressure spike occurs during the removal of the filter cake. This high pressure spike indicates damage to the formation and well bore surface, which damage typically reduces overall permeability of the formation. The rheological properties of the fluid allow it to be used in a number of applications where protection of the original permeable formation is desirable. The applications include, but are not limited to, drilling fracturing and controlling fluid losses during completion operations, such as gravel packing or well bore workovers.
    • 已经发现了使用盐粒子分布,油或水/油乳液,用于将盐颗粒悬浮在油中的悬浮剂和过滤控制剂的油基流体体系。 重要的是,盐颗粒分布在较宽的尺寸范围内以有效地防止过滤或液体流入地层。 由于滤饼颗粒不会侵入井眼,因此在除去滤饼时不会发生高压尖峰。 这种高压尖峰表示对地层和井眼表面的破坏,这种损伤通常会降低地层的总体渗透率。 流体的流变性能允许其用于需要保护原始可渗透地层的许多应用中。 这些应用包括但不限于在完井操作期间的钻孔压裂和控制流体损失,例如砾石填充或井眼工作。
