适用于稠油热采井的预充填防砂筛管
摘要：
本实用新型提供了一种适用于稠油热采井的预充填防砂筛管，所述适用于稠油热采井的预充填防砂筛管包括：外层防砂割缝筛网层；温固型树脂覆膜砂充填层，套接在所述外层防砂割缝筛网层之内；内层防砂割缝筛管层，套接在所述温固型树脂覆膜砂充填层之内；其中，所述外层防砂割缝筛网层、温固型树脂覆膜砂充填层、和内层防砂割缝筛管层，均为管状，并且所述外层防砂割缝筛网层内等间距地间隔设有多个第一梯形割缝。本实用新型采用双层交错梯缝的新型预充填防砂筛管，并在两层梯缝筛管的中间填充有温固型树脂覆膜砂及滤网，能够实现稠油热采井高效防砂的目的。
摘要（英）：

The utility model provides a packing sand control screen pipe in advance suitable for viscous crude thermal production well, packing sand control screen pipe in advance suitable for viscous crude thermal production well includes: outer sand control slot screen cloth layer, the solid type coated sand filled layer of temperature cup joints within the outer sand control slot screen cloth layer, cup joint on inlayer sand control slot screen pipe layer within the solid type coated sand filled layer of temperature, wherein, outer sand control slot screen cloth layer, the solid type coated sand filled layer of temperature and inlayer sand control slot screen pipe layer are the tubulose, and outer sand control slot screen cloth in situ equidistant ground interval is equipped with a plurality of first keystone cuts. The utility model discloses a novel screen pipe of packing sand control in advance of double -deck crisscross ladder stitch to it has solid type coated sand of temperature and filter screen to fill in the middle of two -layer ladder stitch screen pipe, can realize the purpose of the high -efficient sand control of viscous crude thermal production well.
