采用称重法评价了预交联凝胶颗粒的膨胀性能,利用岩心注入实验评价了不同粒径的颗粒与地层的配伍性,选用双管并联模型考察了颗粒的选择性调剖性能。结果表明:预交联凝胶颗粒具有较好的膨胀性能;粒径匹配因子在0.05左右时,颗粒与孔喉的匹配性较好,对非均质地层具有一定的选择性调剖作用,且渗透率级差越大,分流量改善越明显;预交联凝胶颗粒在地层中的运移封堵性有助于提高调剖效果。

The swelling property of the preformed particle gel (PPG)using weighing method and the compatibility between differ-ent sized PPGs and formation using core test were evaluated,and the two sand pack tubes in parallel alinement were chose to study selective profile control of PPGs.The results show that the PPGs have good swelling property.Better compatibility be-tween the PPGs and the pore throat can be indicated when the diameter ratio is approximately 0.05,which also has certain selec-tive profile control for heterogeneous formation;and the larger the permeability ratio,the more significant the flow improvement. The migration sealing property of PPGs in the formation has the contribution in improving the profile control.
