喇嘛甸油田聚合物驱调剖效果

PROFILE CONTROL OF POLYMER FLOODING IN LAMADIAN OILFIELD

通过对喇嘛甸油田阴阳离子聚合物、复合离子聚合物调剖试验效果的分析研究 ,总结了聚合物驱调剖井动态反映特点 ,证实了对油水井间为河道砂体、油层内非均质严重、渗透率级差大的井进行阴阳离子聚合物、复合离子聚合物化学调剖能够封堵高渗透条带 ,降低聚合物采出浓度、扩大波及体积。

This paper summarises the dynamic reaction characteristics of profile control wells during polymer flooding according to the research on profile control test results of anion & cation polymer and compound ion polymer in Lamadian oil field. It conforms that the anion & cation polymer and compound ion polymer chemical flooding performed in high heterogeneous wells which have channel sand body between oil well and water well with high permeability contrast can plug high permeable zone, reduce the recover concentration of polymer, enlarge the swept area and improve the displacement efficiency of polymer.
