The dispersion stability of PFR in the injection water was studied by measuring turbidity as a function of time. In addition, the migration property of the PFR\/HAP dispersion was evaluated by both cellulose membrane filtration and sand packs-flooding experiments. The results show that HAP can stabilize the PFR dispersion prepared with the simulated injection water by forming PFR\/HAP complex molecular aggregates. These aggregates can migrate in sand packs with strong flow resistance due to deformation or disaggregation of the aggregates when passing through the pore throat. Oil recovery was improved by up to 21.1% on the basis of water flooding, and the higher the concentration of PFR\/HAP dispersion system, the better the oil recovery effect. Moreover, the cycle of log-jamming\/dispersion of the aggregates leads to their penetrations through the bigger pores in the sand packs with a higher flow resistance than water. This process can improve the conformance of water in high permeability sand packs on a micro\/macro scale and thus divert more water into low permeability sand packs. Therefore, more oil could be recovered from the low permeability sand packs. Moreover, the bigger the sand pack\u2019s permeability ratio, the lower the oil recovery rate by waterflood, and the more the incremental oil can be recovered by the PFR\/HAP flood.<\/jats:p>","DOI":"10.3390\/polym14153159","type":"journal-article","created":{"date-parts":[[2022,8,3]],"date-time":"2022-08-03T00:15:26Z","timestamp":1659485726000},"page":"3159","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Experimental Study on Phenol-Formaldehyde Resin Aggregates as In-Depth Conformance Control Agents Stabilized by Polymer"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3486-5016","authenticated-orcid":false,"given":"Xianxing","family":"Meng","sequence":"first","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Ankang University, Ankang 725000, China"},{"name":"Ankang Research Centre of New Nano-Materials Science and Technology, Ankang University, Ankang 725000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guiqing","family":"Zhang","sequence":"additional","affiliation":[{"name":"CNPC Engineering Technology Research Co., Ltd., Tianjin 300451, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jian","family":"Wu","sequence":"additional","affiliation":[{"name":"Changqing Downhole Technology CoMPany, CNPC Chuanqing Drilling Engineering Co., Ltd., Xi\u2019an 710000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiong","family":"Zhao","sequence":"additional","affiliation":[{"name":"Shixi Production Plant, Xinjiang Oilfield Company, PetroChina, Karamay 834000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lin","family":"Wang","sequence":"additional","affiliation":[{"name":"Karamay Drilling Company of CNPC Xibu Drilling Engineering Company Co., Ltd., Karamay 834000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fang","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Ankang University, Ankang 725000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"012046","DOI":"10.1088\/1755-1315\/737\/1\/012046","article-title":"The potential of polymer for enhanced oil recovery process on oil refinery: A literature research","volume":"737","author":"Setiati","year":"2021","journal-title":"IOP Conf.
