摘要：
本发明提供一种采油用体膨颗粒调剖剂，具有油田堵水调剖颗粒的强度高，吸水膨胀速率慢，耐热性能好的优点，所述采油用体膨颗粒调剖剂的组成包括：膨润土、珍珠岩、有机铬凝胶、碳酸钙、改性剂、交联剂和引发剂，所述改性剂为碳酸钠，所述交联剂为丙烯酸、丙烯腈、甲基丙烯酸甲酯或N，N-亚甲基双丙烯酰胺，所述引发剂为过硫酸铵、过硫酸钾或亚硫酸氢钠。
摘要（英）：

The invention provides a volume-expansion granular profile control agent for oil recovery, which has the advantages of water shut-off and profile control granules for an oil field as high strength, low water swelling rate and good heat resistance. The volume-expansion granular profile control agent for oil recovery comprises bentonite, pearlite, organic chromium gel, calcium carbonate, a modifying agent, a crosslinking agent and an initiator, wherein the modifying agent is sodium carbonate, the crosslinking agent is crylic acid, acrylonitrile, methyl methacrylate or N,N-methylene bisacrylamide, and the initiator is ammonium persulfate, potassium persulfate or sodium hydrogen sulfite.
