摘要： A method of treating a subterranean formation penetrated by a wellbore of a well having iron-containing components is carried out by introducing a treatment fluid into the wellbore of the well. The treatment fluid is formed from an aqueous solution, a mineral acid, a viscoelastic surfactant gelling agent and corrosion inhibitor system containing at least one of an alkyl, alkenyl, alicyclic or aromatic substituted aliphatic ketone and aliphatic or aromatic aldehyde. The treatment fluid is substantially free of any formic acid or precursor formic acid. In certain embodiments, the corrosion inhibitor system comprises a mixture of at least one of an alkenyl phenone or α,β-unsaturated aldehyde, an unsaturated ketone or unsaturated aldehyde other than the alkenyl phenone and α,β-unsaturated aldehyde, a dispersing agent, an extender and an alcohol solvent. A corrosion inhibitor intensifier may also be used in certain embodiments, which may include a mixture of cuprous iodide and cuprous chloride.

摘要： The improved recovery of hydrocarbons from subterranean formations by hydraulically fracturing a subterranean formation is accomplished. Fracturing fluids using a viscosifying surfactant fluid containing viscosifying micelles, for example, wormlike micelles, are useful to improve recovery of hydrocarbons and limit the loss of fracturing fluid into the formation fracture face. The invention further relates to novel fracturing and acidizing methods useful for increasing hydrocarbon production, limiting water production, resisting fracturing fluid loss into the subterranean formation, and reducing the equipment requirements in mixing and pumping fracturing fluid. The action of viscosifying micelles of surfactant in aqueous zones of the subterranean formation diverts fracturing fluid or acid from the aqueous zones to the hydrocarbon-bearing zones and also facilitates the flowback of increased amounts of hydrocarbons once a fractured well is placed back on production. These methods selectively block the pore structure in a water-bearing zone and do not blocking the pore structure of a hydrocarbon zone at the formation face. The step for selectively blocking forms a plug of a viscous fluid containing viscosifying micelles in the pore structure of the water-bearing zone at the formation face.

摘要翻译：通过水力压裂地下地层来改善地下地层烃类的回收。使用含有增粘胶束（例如蠕虫状胶束）的增粘表面活性剂流体的压裂液可用于改善烃的回收并限制压裂流体进入地层断裂面的损失。本发明还涉及用于增加碳氢化合物生产，限制水的产生，抵抗压裂液渗入地层的压裂和酸化方法，以及减少混合和泵送压裂液的设备要求。表面活性剂粘附在地下水层中的胶束的作用将压裂液或酸从含水区转移到含烃区，并且一旦断裂的井放回生产中，也有利于增加量的烃的回流。这些方法选择性地阻挡含水区中的孔结构，并且不阻塞在形成面上的烃区的孔结构。选择性阻塞的步骤在形成面上的含水区的孔结构中形成含有粘胶束的粘性流体塞。

摘要： The invention provides a method for perforating a well with a perforating fluid comprising a viscoelastic surfactant that essentially stops fluid leak-off after perforation in an overbalanced condition. Another aspect of the invention provides the perforating fluid in itself. The well has a wellbore defined by a generally cylindrical casing in at least a portion of the wellbore (i.e., the wellbore is cased, although it is not necessary cased in its entire length). The wellbore passes through a subterranean formation that comprises hydrocarbon formation fluids (such as oil and/or gas), at least in certain strata. The method comprises placing a perforating device in a wellbore which includes at least one explosive perforating charge that can be detonated in order to perforate the casing and allow the formation fluids to enter the wellbore. The casing is located between the subterranean formation and the perforating device. A perforating fluid including at least one viscoelastic surfactant is placed in the wellbore between the perforating device and the casing, in at least a portion of the wellbore. In other words, the perforating fluid is present in the wellbore adjacent to the perforating device. The explosive charge(s) in the perforating device is detonated, such that the perforating device forms at least one perforation in the casing that permits the flow of hydrocarbon formation fluids from the subterranean formation into the wellbore. As a result of the detonation, at least a portion of the perforating fluid is put in communication with the subterranean formation.
