    摘要： An aqueous hydraulic fluid composition comprising a first lubricant comprising at least one phospholipid and a second lubricant comprising an alkoxylate salt. The aqueous hydraulic fluid composition contains less than about 20% by weight (preferably none or substantially none) of an oil selected from the group consisting of mineral oils, synthetic hydrocarbon oils, and mixtures thereof. The use of alkoxylate salts provides increased lubricity and also acts as an emulsion stabilizer for the composition.

    摘要： It has been discovered that carbonate powders and bicarbonate powders are useful to increase the pH and corrosion resistance of high-density brines, such as zinc bromide brines, without significantly reducing their densities. The carbonates and/or bicarbonates should be water-soluble and may be sodium, potassium, magnesium and/or ammonium carbonates and/or bicarbonates and the like. The carbonates and/or bicarbonates are easily added in powder or other finely divided solid form and are completely dissolved in the brine prior to pumping the brine into a subterranean formation.

    摘要： A process for the preparation of Solid Calcium Bromide Hydrates comprises preparing a highly concentrated Calcium Bromide solution from an initial solution having a lower concentration, bringing it into contact with a cold surface, whereby solid Calcium Bromide hydrates form on said surface, and detaching said solid hydrates from said surface. The concentration of the initial solution is not higher than 60 wt %, typically 52 wt %, and is brought to from 65 to 78 wt %. The said Calcium Hydrates are mainly tetrahydrate Calcium Bromide. The Solid Calcium Hydrates have many uses in the processing of oil wells, for instance preparation of completion fluids, work-over fluids or drill-in fluids in the processing of wells, restoring already used and/or depleted such fluids to the desired, original density. They also have other uses, particularly for soil remediation.

    摘要翻译： 制备固体溴化钙水合物的方法包括从具有较低浓度的初始溶液制备高度浓缩的溴化钙溶液，使其与冷表面接触，由此在所述表面上形成固体溴化钙水合物，并将所述固体 从表面水合。 初始溶液的浓度不高于60重量％，通常为52重量％，并且为65至78重量％。 所述钙水合物主要是四水合溴化钙。 固体钙水合物在加工油井方面有很多用途，例如在加工井中制备完井液，修补液或钻井液，将已经使用和/或耗尽的这种流体还原成所需的原始 密度。 他们还有其他用途，特别是土壤修复。

    摘要： A method is disclosed that affords improved stability to wellbores during drilling in argillaceous formations with water-based drilling fluids. The method comprises adding to the drilling fluid a compound of the invention having the capacity in water to generate a highly efficient membrane on argillaceous materials. The compound is soluble in the drilling fluid at least at the pH at which the compound is added to the drilling fluid or exists in the drilling fluid, but is insoluble in the water in the pores of the argillaceous formations, or at least at the pH of the water in such pores.

    摘要： Improved mud additive compositions are provided which are especially formulated to control hole enlargement due to salt bed erosion during drilling, and to assist in solubilization of deposited salt during well operations. The compositions include a first ingredient such as sodium or potassium ferrocyanide and mixtures thereof, and a second ingredient such as the a phosphonic acid, alkali or alkaline earth metal phosphonic acid salts, or mixtures thereof. The first ingredient is generally present at a level of from about 50-95% by weight in the particulate, dilutable form of the invention, whereas the second ingredient is present at a level of from about 5-50% by weight. The compositions hereof may be added to drilling mud during drilling operations or to fresh water for removing salt depositions.
