Selective water plugging agent and preparation method thereof
The invention discloses a selective water plugging agent and a preparation method thereof, and the selective water plugging agent comprises the following components in parts by weight: 100-150 parts of cement, 10-15 parts of micro-silicon, 10-25 parts of a density regulator, 1-6 parts of a modifier, 0.5-4 parts of an emulsifier, 1-5 parts of a suspending agent, 1-4 parts of a pore forming agent, 1-2 parts of polyester fiber and 150-200 parts of water. The preparation method comprises the following steps: S1, weighing cement, micro-silicon, a density regulator, a suspending agent and polyester fibers, and uniformly mixing to obtain a dry powder mixture; s2, weighing water, adding the dry powder mixture under a stirring condition, and uniformly stirring to obtain a mixed solution I; s3, adding a modifier and an emulsifier into the mixed solution I under a stirring condition, and uniformly stirring to obtain a mixed solution II; and S4, adding a pore-forming agent into the mixed solution II under a stirring condition, and uniformly stirring to obtain the selective water shutoff agent. The surface and the interior of the selective water plugging agent have hydrophobic lipophilicity, so that the relative permeability of oil can be improved, the flow resistance of water is increased, and the effect of plugging water without plugging oil is achieved.
本发明公开了一种选择性堵水剂及其制备方法，所述选择性堵水剂以重量份计，包括100‑150份水泥、10‑15份微硅、10‑25份密度调节剂、1‑6份改性剂、0.5‑4份乳化剂、1‑5份悬浮剂、1‑4份造孔剂、1‑2份聚酯纤维、150‑200份水；所述制备方法包括以下步骤：S1：称取水泥、微硅、密度调节剂、悬浮剂、聚酯纤维，混合均匀，获得干粉混合物；S2：称取水，在搅拌条件下加入干粉混合物，搅拌均匀，获得混合液一；S3：在搅拌条件下向混合液一中加入改性剂和乳化剂，搅拌均匀，获得混合液二；S4：在搅拌条件下向混合液二中加入造孔剂，搅拌均匀，获得选择性堵水剂。本发明选择性堵水剂的表面和内部均具有疏水亲油性，能够提高油的相对渗透率，增加水的流动阻力，达到堵水不堵油的效果。
