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。以聚合物微的膨胀倍率指标，考察了反相乳液聚合体系稳定性的影响因素和深部调驱聚合物微球基本性能的影响因素，结果表明，当油水比为1：1、乳化剂用量>4.5%（相对油相）、聚合温度为60℃，搅拌速度>600 r/ min 时，体系稳定性好、产物成粒性好；合成深部调驱有机颗粒的最佳配比：丙烯酰胺为60 g/ L，丙烯酸为8 g/ L，2-丙烯酰胺基-2-甲基丙磺酸为5.5 g/ L，它们之间的比例为 AM： AA： AMPS =120：16：11，交联剂加量为0.3 g/ L，引发剂加量为0.4 g/ L，约为单体总量的5.4‰。产物为稳定均一的聚合物微球，初始粒径在475.5~525.0 nm，水化膨胀24 h 后，平均粒径为1100 nm。

Using Span60 as emulsifying agent;the hexamethylene as oil-phase;MBA as cross-linker;su-perphosphate potassium as the initiator;the organic in-depth performance control particulate was synthe-sized. Using the gel swelling multiple and viscoelasticity as index,the stability of inverse emulsion poly-merization and the basic character of in-depth performance control particulate were investigated. The result showed the polymerization system and the particulate-forming ability were very well when the ratio of oil and water was 1: 1;the amount of emulsifying agent was 4. 5% ;the temperature was 60 ℃;the stirring speed was 600 r/ min,the optimum of polymerization:initiator 0. 4 g / L;cross-linker 0. 3 g / L;AMPS 5. 5 g / L;acrylic acid 8 g / L;AM 60 g / L,and AM: AA: AMPS = 120: 16: 11. The polymericparticle is uni-form,and the initial size is between 475. 5 ~ 525. 0 nm,after hydrating 24 h,the average size is 1 100 nm.
