摘要： A method of retarding the flow of water in a subterranean formation that includes injecting a gelling pill into the formation, the gelling pill comprising: brine; a crosslinkable polymer; and a crosslinkant; and allowing the crosslinkable polymer to crosslink to form a gel in the subterranean formation is disclosed. A water absorbing polymer is optionally included.

摘要： A method of cleaning a wellbore prior to the production of oil or gas is disclosed, wherein the wellbore has been drilled with an invert emulsion drilling mud that forms an invert emulsion filter cake. The method may include the steps of circulating a breaker fluid into the wellbore, where the breaker fluid includes an aqueous fluid, a water soluble polar organic solvent, a hydrolysable ester of a carboxylic acid, and a weighting age, and where the hydrolysable ester is selected so that upon hydrolysis an organic acid is released and the invert emulsion of the filter cake breaks.
摘要翻译： 公开了在生产油或气体之前清洁井眼的方法，其中已经用形成反转乳液滤饼的反转乳液钻井泥浆钻了井筒。 该方法可以包括以下步骤：将破坏剂流体循环到井筒中，其中破碎剂流体包括水性流体，水溶性极性有机溶剂，羧酸的可水解酯和加权酸，并且其中可水解酯是 选择使得在水解时释放有机酸，并且滤饼的反转乳液破裂。

摘要： A method of cleaning a wellbore prior to the production of oil or gas, wherein the wellbore has been drilled with an invert emulsion drilling mud that forms an invert emulsion filter cake is disclosed. The method may include circulating a breaker fluid into the wellbore, where the breaker fluid includes a non-oleaginous internal phase and an oleaginous external phase, where the non-oleaginous phase includes a water soluble polar organic solvent, a hydrolysable ester of a carboxylic acid, and a weighting agent, and the oleaginous external phase includes an oleaginous fluid and an emulsifier, and where the hydrolysable ester is selected so that upon hydrolysis an organic acid is released and the invert emulsion of the filter cake breaks.
摘要翻译： 公开了一种在生产油或气体之前清洁井筒的方法，其中已经钻了井眼已经钻出了形成反相乳液滤饼的反相乳液钻井泥浆。 该方法可以包括将破坏剂流体循环到井眼中，其中破碎剂流体包括非油质内相和油质外相，其中非油质相包括水溶性极性有机溶剂，可水解的羧酸酯 和加重剂，并且油质外相包括油性流体和乳化剂，并且其中选择可水解酯，使得在水解时释放有机酸，并且滤饼的反转乳液破裂。
