摘要：
Some embodiments herein described relate to method comprising : providing a portion of a subterranean formation comprising unconsolidated particulates; introducing a polymerizable aqueous consolidation composition into the portion of the subterranean formation so as to contact the unconsolidated particulates with the polymerizable aqueous consolidation composition, thereby creating coated, unconsolidated particulates; introducing a substantially solids-free, aqueous flush fluid into the portion of the subterranean formation so as to remove the polymerizable aqueous consolidation composition from interstitial spaces between the coated, unconsolidated particulates; introducing a water- soluble polymerization initiator composition into the portion of the subterranean formation so as to contact the coated, unconsolidated particulates; and consolidating the coated, unconsolidated particulates in the portion of the subterranean formation.
摘要（中）：
本文描述的一些实施例涉及包括以下方法：提供包含未固结颗粒的地下地层的一部分; 将可聚合的水性固结组合物引入所述地层的所述部分中，以使所述未固结的颗粒与所述可聚合的水性固化组合物接触，由此产生涂覆的，未固化的颗粒; 将基本上不含固体的含水冲洗流体引入所述地层的所述部分中，以从所述涂覆的未松散颗粒之间的间隙中除去所述可聚合水性固结组合物; 将水溶性聚合引发剂组合物引入所述地层的所述部分中以与所述涂覆的未松散的颗粒接触; 并且将地下地层部分中的涂覆的，未固结的颗粒固结。
