中文摘要:
      水平井裸眼防砂主要面临完井地层易坍塌, 粉细砂油藏滤砂管易被堵塞, 裸眼水平井砾石充填难以实现环空均匀饱和填砂等问题。针对上述问题, 研制了具有形状记忆功能的聚氨酯类自膨胀防砂筛管材料, 研究了驱替小样的形状记忆性能、 渗透性能、 抗压性能和耐酸碱性能, 考察了聚氨酯筛管样件的流通性和挡砂精度。结果表明, 该聚氨酯材料形状记忆功能良好, 形状回复和膨胀受温度影响较大, 温度越高, 形状回复率越大, 形状回复越快, 温度达到 90℃以上时的形状回复率大于 99%, 基本回复到初始状态; 该聚氨酯材料膨胀率随温度升高而增加, 最大可达 400%。所制备的聚氨酯压缩材料回复至初始状态后的渗透率为 180×10-3~200×10-3μm2, 抗压强度为 1~3 MPa, 耐酸碱性良好。与树脂滤砂管相比, 聚氨酯筛管样件流通性差, 挡砂精度高。图3表 6参9
英文摘要:
      The reservoir collapse, screen blocked and gravel packing difficult to pack densely were the main problems in open hole of horizontal well. To solve these problems, a polyurethane-expandable material that had shape memory function was developed. The shape memory, permeability, compression resistance and acid and alkali resistance of polyurethane demo were studied, and the throughput capacity and sand control accuracy of polyurethane sieve tube sample were investigated. The results showed that the shape memory function of polyurethane material was good. The shape recovery and expansion were affected by temperature. The higher temperature, the higher shape recovery rate and the faster shape recovery were. The shape recovery rate was above 99% and polyurethane material returned to the initial state when the temperature reached 90℃. The expansion rate of polyurethane material increased with increasing temperature, which maximum value was up to 400% . The permeability of polyurethane compression material after returned to the initial state was 180 × 10-3—200 × 10-3 μm2, and the compressive strength was 1—3 MPa. The polyurethane material had good acid and alkali resistance. Compared with the resin screen, the polyurethane sieve tube sample had poor throughput capacity and high sand control accuracy.
