微细颗粒型水平井堵水剂组合物及其应用
摘要：
本发明提供了一种微细颗粒型水平井堵水剂组合物及其应用，该堵水剂组合物的原料组成包括微细颗粒型无机胶凝剂、激活剂、缓凝剂和分散剂，各组分重量配比为：微细颗粒型无机胶凝剂10～60重量份，激活剂2～10重量份，缓凝剂5～15重量份，分散剂1～5重量份；该胶凝剂是由低钙白云石、高硅型铁尾矿与粘土按照1：2.5～3.5：0.5～2.5的重量比混合后经烧制、研磨而成。本发明的微细颗粒型水平井堵水剂组合物在常温下即可配制成悬浮液作为堵水剂使用，降低操作成本，且具有高水硬性、高度缓凝性、高封堵率，为油田提供高性价比的调堵材料。
摘要（英）：

The invention provides a fine particle type horizontal well water plugging agent composition and an application thereof; the water plugging agent composition comprises the raw materials by weight: 10 to 60 parts by weight of a fine particle inorganic gelling agent, 2 to 10 parts by weight of an activator, 5 to 15 parts by weight of a set retarder, and 1 to 5 parts by weight of a dispersant; the gelling agent is formed by sintering and grinding low-calcium dolomite, high-silicon iron tailings and clay according to the weight ratio of 1:(2.5-3.5):(0.5-2.5). The fine particle type horizontal well water plugging agent composition can be made into a suspension as a water plugging agent at room temperature for use, reduces operating costs, has the advantages of high hydraulicity, high set retarding performance and high plugging rate, and provides a plugging adjusting material with high price/performance ratio for oil fields.
