针对目前金属滤、化学滤对孤东油田注聚区存在防砂周期短、提液效果不明显等问题，通过室内实验，从6种树脂中优选出湿热性能好、力学性能及耐热性能佳的氰酸酯树脂作为基底，结合实验得到的最佳配比进行成型改进，最终得到一种具有高强度、高渗透率、抗堵塞的高渗透滤砂管。该滤砂管滤的砂器与中心管保持5 mm 的过油间隙，增加了过油面积，提高了渗透率，同时具有更强的抗压抗折性，以及挡砂能力强、不易堵塞、耐化学性等优点，适合在疏松砂岩油藏的注聚区广泛应用。目前，现场已试验6井次，平均单井日增液34.2 m3，增液幅度91.9%，单井日增油1.8 t，动液面上升159.2 m，提液增油效果明显。

In view of the problems that the metal filter and chemical filters now used in polymer injected areas in Gudong Oilfield have a short sand control period and are not obvious in lifting the fluid, cyanate ester resin with favorable hydrothermal properties, me-chanical property and heat-resistant performance is selected from six types of resins by lab experiments and used as substrate, which after further molding and improvement as per the optimum ratio obtained from the lab tests, finally produces a high-permeability screen tube with high strength and resistance to blocking. This screen tube filter has a 5 mm clearance to the center pipe, which increases the oil flow area and improves the permeability; meanwhile, it is characterized by strong compression resistance and bending resistance, strong sand control, not being easily blocked and resistance to chemical corrosion; it is suitable for extensive application in polymer injected areas of unconsolidated sandstone reservoirs. At present, tests of 6 well times have been carried out, and the average fluid increase is 34.2 m3 per day, up by 91.9%; oil production per day is increased by 1.8 t, and the working fluid level is increased by 159.2 m, generating obvious effectiveness in lifting the fluid level and increasing oil production.
