A method of treating a subterranean formation comprising the steps of providing a gelled liquid hydrocarbon treatment fluid comprising a liquid hydrocarbon and a gelling agent that comprises a polyvalent metal salt of an organophosphonic acid ester or a polyvalent metal salt of an organophosphinic acid, and treating the subterranean formation with the gelled liquid hydrocarbon treatment fluid. The gelled liquid hydrocarbon treatment fluids of the present invention are suitable for use in subterranean treatment operations, such as subterranean stimulation and sand control treatments like fracturing and gravel packing, that may be carried out in subterranean formations for the production of hydrocarbons. The compositions and methods of the present invention also may be suitable, for example, to be used as plugging agents, well bore cleanup fluids, viscous sweep fluids, or insulating fluids to be used in associated methods.
一种处理地下地层的方法,包括以下步骤:提供一种胶凝液态烃处理液,该处理液由液态烃和胶凝剂组成,胶凝剂包括有机膦酸酯的多价金属盐或有机膦酸的多价金属盐;用胶凝液态烃处理液处理地下地层。本发明的胶凝液态烃处理液适用于地下处理作业,如地下刺激和防砂处理,如压裂和砾石填料,这些作业可在地下地层中进行,以生产碳氢化合物。本发明的组合物和方法还可用作堵塞剂、井眼清理液、粘扫液或相关方法中使用的绝缘液等。
