一种低密度、高强度可降解暂堵剂及其制备方法
摘要：
本发明提供一种低密度、高强度可降解暂堵剂，包括以重量百分比的组分：聚乳酸60％-85％，淀粉5-20％，聚己内酯5-10％，增溶剂2-5％，增韧剂2-5％。本发明的可降解暂堵剂是一种刚性暂堵模式，能在已有裂缝中形成桥堵，暂堵升压明显。
摘要（英）：

The invention provides a low-density and high-strength degradable temporary plugging agent. The low-density and high-strength degradable temporary plugging agent comprises the following components inpercent by weight: 60-85% of polylactic acid, 5-20% of starch, 5-10% of polycaprolactone, 2-5% of a solubilizer and 2-5% of a toughening agent. The degradable temporary plugging agent adopts a rigid temporary plugging mode, can form bridge plugging in an existing crack, and has an obvious temporary plugging boosting effect.
