摘要： Improved methods of treating water and hydrocarbons producing subterranean formations to reduce the water permeabilities of the formations without substantially reducing the hydrocarbons permeabilities thereof are provided. The methods basically comprise introducing into the formation a chemical which does not resist water flow and attaches to adsorption sites on surfaces within the porosity of the formation but slowly washes off the sites as another fluid flows through the treated formation. Thereafter, a water flow resisting polymer is introduced into the formation so that it flows deeply into the porosity of the formation before the previously introduced chemical washes off and attaches to the adsorption sites as the chemical washes off.

摘要： Methods of using water-soluble hydrophobically modified polymers to treat intervals of a subterranean formation having variable permeabilities. An exemplary embodiment provides a method of treating an interval of a subterranean formation having a permeability that varies. The method comprises contacting the interval with a water-soluble hydrophobically modified polymer capable of selectively reducing the effective permeability of the interval to water without a comparable reduction of the effective permeability of the interval to hydrocarbons. The hydrophobically modified polymer modifies the interval to have a more uniform permeability without substantially preventing the flow of fluids through the interval. The method further comprises introducing a treatment fluid into the interval. The more uniform permeability of the interval allows for a more uniform treatment of the interval by the treatment fluid than would be allowed without treatment of the interval with the hydrophobically modified polymer.
摘要翻译：使用水溶性疏水改性聚合物处理具有可变渗透性的地层的间隔的方法。一个示例性实施例提供了一种处理具有变化的渗透性的地层的间隔的方法。该方法包括使该间隔与水溶性疏水改性聚合物接触，所述聚合物能够选择性地将间隔物的有效渗透性降低至水，而不会将烃区间的有效渗透率相当地降低。疏水改性的聚合物将间隔改变为具有更均匀的渗透性，而基本上不会阻止流体流过间隔。该方法还包括将处理流体引入该间隔。间隔的更均匀的渗透性允许处理流体对间隔进行更均匀的处理，而不用处理与疏水改性的聚合物的间隔。

摘要： The present invention provides a method of controlling fluid loss to a permeable formation penetrated by a wellbore. A novel fluid loss agent is prepared by forming a crosslinked polymer gel which then is sheared to break the gel into discrete particles of a particular size range. A slurry then is formed of the particles by dispersing the particles in an aqueous fluid having a density similar to that of the gel particles. The slurry then is introduced into contact with the permeable formation and a filter cake of the particles is formed upon contact with the formation and loss of the slurrying fluid to the formation. The filter cake provides further fluid loss control to the permeable formation.
