摘要： Hydrocarbon fracturing fluids are made by combining organic phosphate esters with polyvalent metal salts in hydrocarbon carriers to form gels; breaking of the gel is retarded or otherwise controlled over a wide range of water concentrations, through the use of slowly soluble alkaline earth metal compounds, preferably hard burned magnesium oxide, which may be added along with the gel component. The slowly soluble alkaline earth metal compound is employed together with an oily acid breaker retarding agent such as tall oil.

摘要： In the removal of particulates from a wellbore, such as in air drilling for hydrocarbon recovery, a mixture of an amphoteric foaming agent and, typically, an anionic surfactant is employed. An aqueous solution thereof having a pH of at least 9.5 is used to generate a foam for removing the particulates; then the foam is collapsed by the introduction of acid to reduce the pH below about 4, the particles are removed mechanically, the pH is restored to greater than 9.5, and the foaming solution is returned to the wellbore. The solution may be used several times; partial losses of foaming agent in the process may be easily replenished with each cycle. Cationic surfactants may be used instead of anionic, with foaming and foam collapse being controlled at opposite pH's. Savings are realized in water, drilling chemicals, and settling pits and the like for removing particulates from the foam.
摘要翻译：在从井眼中除去颗粒物，例如用于烃回收的空气钻井中，采用两性发泡剂和通常为阴离子表面活性剂的混合物。使用其pH为至少9.5的水溶液来产生用于除去微粒的泡沫体; 然后通过引入酸将泡沫压扁以将pH降低到约4以下，机械地除去颗粒，pH恢复到大于9.5，并且将发泡溶液返回到井眼。该溶液可以使用多次; 在该过程中发泡剂的部分损失可以容易地在每个循环中补充。可以使用阳离子表面活性剂代替阴离子表面活性剂，发泡和泡沫崩溃控制在相反的pH值。在水，钻井化学品和沉降坑等中实现储存以从泡沫中除去微粒。

摘要： Swelling and migration of subterranean clay is inhibited during drilling for and stimulation of the production of hydrocarbon fluids, and preparation therefor, by treating said formations with a copolymer of about 5% to about 50% of an anionic monomer such as acrylic acid, methacrylic acid, or 2-acrylamido-2-methyl propane sulfonic acid and the balance a cationic monomer selected from dimethyl diallyl ammonium chloride, or acryloxy or methacryloxy ethyl, propyl or 3-methyl butyl trimethyl ammonium chlorides or methosulfates. Permeability damage to the formation is reduced in the presence of the copolymer; it is particularly effective in spite of the presence of a foaming agent.
