摘要： Emulsified acids have been used to increase production rates of oil and gas in carbonate reservoirs through acid fracturing and matrix acidizing operations. An emulsifier is used to emulsify the aqueous acid with an oil, usually diesel. Very small particles, such as colloidal clay particles and/or nanoparticles increase the stability of the emulsified acids over an elevated temperature range.

摘要： A fracturing fluid, gravel pack fluid and/or frac pack fluid containing particles such as proppants, gravel and/.or sand, may contain an effective amount of a nano-sized particulate additive to fixate or reduce fines migration, where the particulate additive is an alkaline earth metal oxide, alkaline earth metal hydroxide, alkali metal oxides, alkali metal hydroxides transition metal oxides, transition metal hydroxides, post-transition metal oxides, post-transition metal hydroxides piezoelectric crystals and pyroelectric crystals. The nano-sized particulate additive is optionally bound to the particles with a coating agent such as an oil, alcohol, glycol, glycol ethers, ketones, terpenes, etc. The particle size of the magnesium oxide or other agent may be nanometer scale but may be a larger scale than nanometer but still relatively small, which scale may provide unique particle charges that help fixate the formation fines. The carrier fluid used in the treating fluid may be aqueous, brine, alcoholic or hydrocarbon-based.

摘要： Compositions Including Relatively Low Reactivity Acids, Mixed with viscoelastic surfactants (VESs) and internal breakers may serve as drill-in fluids to open underground hydrocarbon reservoirs with carbonate contents of 10 wt % or above. The drill-in fluids have low viscosities in the drilling pipe. After the fluid flows out of the drill bit, the acids react with carbonates in the formation thereby increasing the pH of the drill-in fluids causing the VES to gel the fluid at the bottom of the hole and the downhole annulus between the drilling pipe and the formation rock. The viscosified drill-in fluid will reduce fluid loss and will carry no dissolved drilling debris to the surface. After drilling through the targeted formation, the internal breakers in the viscosified drill-in fluids will break down the fluids to permit their removal, and the well is ready to produce with very little or no near well bore damage.
摘要翻译：包含相对低反应性酸的组合物与粘弹性表面活性剂（VES）和内部破碎剂混合可用作钻入液体，以打开碳酸盐含量为10重量％或更高的地下储层。钻孔液在钻井管中具有低粘度。在流体流出钻头之后，酸与地层中的碳酸盐反应，从而增加钻入流体的pH，使得VES将孔底部的流体和钻井管和钻井孔之间的井下环空凝结形成岩石。粘稠钻井液将减少流体损失，并且不会在表面上携带溶解的钻屑。在钻孔通过目标地层后，粘稠钻井液中的内部破碎机将分解流体以允许它们的移除，并且井准备好产生很少或没有接近井眼损坏。

摘要： The handling, transport and delivery of particulate materials, particularly fine particles, may be difficult. Alkaline earth metal oxide particles such as magnesium oxide (MgO) may be suspended in glycerin and/or alkylene glycols such as propylene glycol up to loadings of 51 wt %. Such suspensions or slurries make it easier to deliver MgO and similar agents into fluids, such as aqueous fluids gelled with viscoelastic surfactants (VES). The MgO serves as stabilizers and/or fluid loss control agents for VES-gelled fluids used to treat subterranean formations, e.g. for well completion or stimulation in hydrocarbon recovery operations. The particle size of the magnesium oxide or other agent may be between 1 nanometer to 0.4 millimeter.
摘要翻译：颗粒材料，特别是细颗粒的处理，运输和输送可能是困难的。碱土金属氧化物颗粒例如氧化镁（MgO）可以悬浮在丙三醇和/或亚烷基二醇如丙二醇中，其负载量为51wt％。这种悬浮液或浆料使得更容易将MgO和类似的试剂递送到流体中，例如用粘弹性表面活性剂（VES）凝胶化的含水流体。 MgO用作用于处理地下地层的VES凝胶流体的稳定剂和/或流体损失控制剂，例如。用于在油气回收操作中完成或刺激。氧化镁或其它试剂的粒径可以在1毫米至0.4毫米之间。

摘要： Viscoelastic surfactant (VES) based fluid systems for zone isolation and flow control are effective in water and/or gas shutoff applications. The fluid systems may include brine, a viscosity enhancer, as well as the VES, and optionally a stabilizer for high temperature applications. The stabilizer may be an alkali earth metal oxide, alkali earth metal hydroxide, alkali metal oxide, alkali metal hydroxide, Al2O3, and mixtures thereof. The viscosity enhancer may include pyroelectric particles, piezoelectric particles, and mixtures thereof. The fluid system is easy to pump into the formation, and after pumping, the fluid system will generate very high viscosities to prevent the VES fluid from flowing back to stop undesirable water and/or gas production.
