| 摘 要： | 针对胜利油田注聚合物区块油井防砂层的堵塞问题,通过X射线衍射、显微观察、激光粒度和氧化铝色谱等分析手段,对注聚区油井防砂层注聚前后砂样的形态和表面物种组成进行分析;分析聚丙烯酰胺(PAM)的降解机制,并进行解堵剂的优选.结果表明:造成防砂层堵塞的主要原因是聚丙烯酰胺在砂粒表面的聚集、吸附作用,此外还有地层中矿物质微粒的运移,以及聚合物、原油组分与地层微粒在防砂层共同的作用;优选出的AY-1型和AY-2型2种解堵剂对聚合物的降解效果良好.

| Abstract: | The plugging of the sand control area in the polymer injection wells was investigated.The sand samples morphologic characteristics before and after polymer injecting and species component on the surface were analyzed by using XRD,microscopic observation,laser particle,alumina chromatographical analysis.The mechanism of the polymer degradation was studied,and the plug removing agent was optimized.The results show that the main reason for the plugging of the sand control area was adsorption,gathering and brid... |
