摘　　要：开发的适合于多层防砂的KV-3型网络覆膜砂,可以延时固化,具有较高的强度和渗透率,因此可以用一次防砂管柱实现多层防砂施工的目的,人为地控制固化。该网络覆膜砂具有较高的强度和渗透率,在70℃左右条件下,固化剂质量分数为25%-30%时,抗折强度可达2.5MPa,抗压强度可达4.7MPa。KV-3 net resin coated sand used for multi-layers sand control could be solidified postponably, it had high strength and penetration coefficient, so multi-layers sand control could be realized by once sand control pipe and solidification could be controlled by man. Under conditions of about 70 ℃ and solidifier quality fraction 25%-30%, flexural strength and compressive strength could reach 2.5 MPa and 4.7 MPa respectively.
