摘要： Embodiments of the present disclosure include a wellbore servicing fluid that includes a diluent, a hydrophobically modified polymer, and a base. The base provides the wellbore servicing fluid with a pH of greater than 10. The presence of the base in the wellbore servicing fluid helps to minimize changes in the viscosity of the wellbore servicing fluid when a deposit, or a kick, of salt is encountered during the drilling operation.

摘要： Flexible polyurethane foams are made using certain hydrolysable silane compounds in the foam formulation. The hydrolysable silane compounds contain at least one isocyanate-reactive group and at least one hydrolysable silane group. The presence of the hydrolysable silane compound in the foam formulation leads to improved tensile, tear and elongation properties without an adverse effect on other important foam properties such as resiliency and hysteresis loss.
摘要翻译：柔性聚氨酯泡沫在泡沫配方中使用某些可水解的硅烷化合物制成。可水解硅烷化合物含有至少一个异氰酸酯反应性基团和至少一个可水解硅烷基团。泡沫制剂中可水解硅烷化合物的存在导致拉伸，撕裂和伸长性能的改善，而对其它重要的泡沫性能如弹性和滞后损失没有不利影响。

摘要： Disclosed is a composition and a method for cementing a casing in a borehole of a well using an aqueous cementing composition comprising (a) water, (b) a cementing composition comprising (i) a hydraulic cement, (ii) an anionically- and hydrophobically- modified polymer, (iii) a dispersant, and optionally (iv) one or more other additives conventionally added to aqueous cementing compositions useful in cementing casings in the borehole of wells. Preferably the anionically- and hydrophobically-modified hydroxyethyl cellulose has an ethylene oxide molar substitution of from 0.5 to 3.5, a hydrophobe degree of substitution of from 0.001 to 0.025, an anionic degree of substitution of from 0.001 to 1, and a weight-average molecular weight of from 100,000 to 4,000,000 Daltons and the dispersant is sulfonated polymer, melamine formaldehyde condensate, a naphthalene formaldehyde condensate, a branched or non-branched polycarboxylate polymer. Preferably, the aqueous cementing composition is pumped downwardly into said casing, pumping upwardly into the annulus surrounding said casing until said aqueous composition fills that portion of the annular space desired to be sealed, and then maintaining said aqueous cementing composition in place until the cement sets.
