Abstract
1. Способ индуцирования агрегации расклинивающего агента в трещине гидроразрыва, включающий этапы (1) приготовления жидкости-носителя расклинивающего агента, вязкость которой повышена путем использования первого полимерного геля, способного к синерезису; (2) закачивания суспензии расклинивающего агента и упомянутой жидкости в скважину; и (3) инициирования синерезиса геля.2. Способ по п.1, где упомянутая жидкость-носитель также содержит волокна.3. Способ по п.1, где по меньшей мере часть используемого расклинивающего агента имеет полимерное покрытие.4. Способ по п.1, где упомянутый полимерный гель представляет собой сшитый гель.5. Способ по п.1, где упомянутый полимерный гель представляет собой сшитый боратом полимерный гель, а упомянутый синерезис инициируется введением в гель поливалентного катиона.6. Способ по п.5, где упомянутый поливалентный катион представляет собой катион металла, выбираемого из группы, состоящей из Ca, Zn, Al, Fe, Cu, Co, Cr, Ni, Ti, Zr, а также их смесей.7. Способ по п.5, где упомянутый катион вводится в гель путем растворения соли, оксида или гидроксида катиона.8. Способ по п.5, где упомянутый катион на момент инициирования синерезиса находится в форме гидроксида.9. Способ по п.1, где упомянутый синерезис вызывается избыточной сшивкой полимерного геля.10. Способ по п.9, где избыточная сшивка геля задержана путем использования задерживающего сшивку агента.11. Способ по п.9, где избыточная сшивка геля индуцируется инкапсулированным сшивающим агентом, медленно растворяющимся сшивающим агентом, либо температурно-активируемым сшивающим агентом.12. Способ по п.1, где упомянутый синерезис вызывается путем введения в сост�1. A method of inducing proppant aggregation in a hydraulic fracture, comprising the steps of (1) preparing a proppant carrier fluid, the viscosity of which is increased by using a first polymer gel capable of syneresis; (2) pumping the proppant slurry and said fluid into the well; and (3) initiating gel syneresis. 2. The method of claim 1, wherein said carrier liquid also comprises fibers. The method of claim 1, wherein at least a portion of the proppant used has a polymer coating. The method of claim 1, wherein said polymer gel is a crosslinked gel. The method according to claim 1, wherein said polymer gel is a borate-crosslinked polymer gel, and said syneresis is initiated by introducing a polyvalent cation into the gel. The method of claim 5, wherein said polyvalent cation is a metal cation selected from the group consisting of Ca, Zn, Al, Fe, Cu, Co, Cr, Ni, Ti, Zr, and mixtures thereof. The method according to claim 5, wherein said cation is introduced into the gel by dissolving the salt, oxide or hydroxide of the cation. The method according to claim 5, wherein said cation is in the form of a hydroxide at the time of syneresis initiation. The method of claim 1, wherein said syneresis is caused by excessive crosslinking of the polymer gel. The method of claim 9, wherein excess crosslinking of the gel is delayed by the use of a crosslinking agent. The method of claim 9, wherein excess crosslinking of the gel is induced by an encapsulated crosslinker, a slow dissolving crosslinker, or a temperature activated crosslinker.
