一种聚合物微球驱油效果影响因素研究

Research on the Influential Factors of Oil Displacement Effect of Polymeric Particle

以环己烷为连续相,Span60为乳化剂,过硫酸钾为引发剂,N'N-亚甲基双丙烯酰胺为交联剂、合成了深部调驱用聚合物微球,并从不同的聚合物微球注入体积与注入浓度对驱油效果进行研究。结果表明,微球水化膨胀期为五天,此时D(0.9)为10.7μm,且在相同条件下,其原油采收率随着聚合物微球注入体积,注入浓度的增大而增大。

Using Span60 as emulsifying agent, the hexamethylene as oil- phase, MBA as cross- linker, superphosphate potassium as the initiator, the organic in- depth performance control particulate was synthesized. The influential factors of oil displacement effect from different injected volume and different injected concentration were studied. The results showed that the particulate hydration expansion period for five days, and the D（0.9）was 10. 7 μm, and in the same conditions, the recovery was increasing with a higher injected volume or concentration of polymeric particle.
