Oil-containing sludge profile-control plugging agent and preparation method thereof

The invention provides an oil-containing sludge profile-control plugging agent and a preparation method thereof. The oil-containing sludge profile-control plugging agent is prepared from the followingraw materials in parts by weight: 3 to 20 parts of oil-containing sludge, 0.2 to 1.0 part of dispersing agent, 0.2 to 0.5 part of suspension stabilizer, and 79.6 to 95.5 parts of water. The phenomenon that the oil-containing sludge profile-control plugging agent agglomerates, and is difficult to stably suspend and scatter can be effectively prevented, a better profile control effect on an oil layer can be achieved, the injection performance is improved, and simple operation, convenience in use and low cost are achieved. 本发明提供了种含油污泥调剖堵剂及其制备方法，含油污泥调剖堵剂由包括以下的原料制成：含油污泥3-20重量份、分散剂0.2-1.0重量份、悬浮稳定剂0.2-0.5重量份和水79.6-95.5重量份。本发明能够有效防止含油污泥调剖堵剂聚团、难以稳定悬浮分散的现象，可对油层起到更好的调剖效果，提高了注入性能，并且操作简单，使用方便，成本低。
