摘要： A method for treating a fines-containing formation to prevent the migration and/or swelling of particulate matter. The method comprises injecting into the formation water and/or steam which contains at least one water-soluble organosilicon compound. Suitable compounds include those which are not normally considered to be water-soluble, but which hydrolyze to form water-soluble materials such as silanols.

摘要： A filter cake deposited by a drilling fluid, drill-in fluid or fluid loss control pill may be removed from a wellbore by introducing into the wellbore a dispersing agent of an organic amino phosphonic acid, ester or salt. The dispersing agent forms a dispersion containing at least a portion of the drilled solids. The dispersing agent may be introduced into the wellbore as a component of a filter cake removal treatment fluid or either prior to or after introduction of the filter cake removal treatment fluid.

摘要： Subterranean formations are treated with acid, by a method comprising the steps of: (1) forming an acidizing composition by mixing an aqueous acid component with at least one water-soluble organosilicon compound; and (2) injecting the composition into the formation. Suitable organosilicon compounds include water-soluble organosilanes and organosilanes which hydrolyze to form water-soluble silanols. By using the organosilicon compound, movement of formation fine particles is inhibited and swelling of clays by aqueous fluids is reduced, thus tending to maintain formation permeability.

摘要： The productivity of sandstone or carbonate formations is enhanced by contacting the formation with a deformable particulate and a HF-containing acidizing solution. The deformable particulates create a partial monolayer in the formation while the HF-containing acidizing solution differentially etches the rock around the deformable particulate. The surface of the formation is partially blocked from reaction with the acidizing solution by the creation of the partial monolayer. Conductive channels are therefore created on the surface of the formation. The deformable particulates deform on closure. As the closure stress increases, the formation faces compress the non-dissolved, sandwiched formation points. These points function as pillars of un-reacted formation and act similar to a partial monolayer of proppant, providing the highly conductive channels.
摘要翻译：通过使地层与可变形的颗粒和含HF的酸化溶液接触，提高砂岩或碳酸盐岩层的生产率。可变形颗粒在地层中产生部分单层，而含HF的酸化溶液在可变形颗粒周围差异地蚀刻岩石。通过产生部分单层，地层的表面部分被阻止与酸化溶液的反应。因此，导电通道在地层的表面上产生。可变形的颗粒在闭合时变形。随着闭合应力增加，形成面压缩未溶解的夹层形成点。这些点作为未反应形成的柱子起作用，类似于支撑剂的部分单层，提供高导电通道。

摘要： A method for treating a subterranean formation, or a well penetrating the formation, comprises injecting into the well an aqueous composition containing an aminopolycarboxylic acid and a water-soluble organosilicon compound. By use of the method, scale is removed from well equipment and/or openings in the formation, and fine particles within the formation are stabilized to prevent their subsequent movement, resulting in increased, more stable fluid flow through the formation and well.

摘要： A fluid flow model is comprised of one cross-flow style core holder and a multitude of standard style core holders, all connected by a concurrent combination of serial and parallel flow paths. The sum of these flow paths yields a fluid flow model that closely approximates a small radial slice of a conventional reservoir. The fluid flow model has particular applicability to estimate the requisite treatment fluid for use in acidizing as well as water control methods.

摘要： A method of stimulating subterranean formations in oil and gas wells using a high pH buffered acid system. The method may be used to treat sandstone formations wherein the pH buffered acid system is used as the preflush or overflush or both. The method consists of introducing into the well a hydrofluoric acid containing sandstone acidizing solution either prior to or subsequent to introduction of the pH buffered acid system. The pH buffered acid system may further be used in the treatment of carbonate reservoirs. The pH of the buffered acid solution is substantially equivalent to that of the pH of the acidizing solution. The buffered acid solution is void of either hydrofluoric acid or hydrofluoric acid precursors.
