摘要
预交联体膨型凝胶颗粒是新近提出的一种油田用新型深部调剖剂,是将一定浓度的主剂、交联剂、引发剂、添加剂、增强剂和热稳定剂等混合均匀,在地面环境下交联,然后经烘干、干燥、粉碎等工艺过程形成的凝胶颗粒。该颗粒是一种吸水性树脂,能够吸水膨胀,且膨胀后的颗粒具有一定的弹性、强度和保水功能,具有抗温抗盐性能好、配制简单、施工方便、对非目的层污染少等优点。影响凝胶颗粒性能的因素很多。重点研究了交联体系中的各组分含量等内在因素对凝胶颗粒黏弹性和吸水性能的影响,并给出了凝胶体系的合理配比。图7参4（白宝君摘）
A new kind of in-depth deverting agent, called pre-gelled particle, has been developed to control conformance of mature reservoirs. The particles are formed from gels on the ground using gelation system, and then experience several processes such as particle forming, baking, pulverizing, and sieving. The gel particles disperse in water, but they do not dissolve in it. This paper mainly analyzes the influence of acrylamide, crosslinker, initiator, additive and heat stabilizer on elastic modulus and swelling ability of gel particles. The best formula ratio is given for this kind of gel particle.
