吉林油田扶余采油区2口水平井通过注入新型复合表活剂,自2月以来措施增产65吨。吉林油田原油流动性差,吞吐后期“出液不出油”问题严重。通过优选储层物性好、相对封闭区块,优化段塞组合方式,尝试由单一表活剂吞吐向二氧化碳复合吞吐方向发展。科研人员以磺酸盐与有机添加剂复配为主,共完 Two horizontal wells in the Fuyu Oil Production Area of ​​Jilin Oilfield have increased their production by 65 tons since February due to the injection of a new composite surfactant. Jilin Oilfield crude oil mobility is poor, post-throughput “out of liquid not ” a serious problem. By optimizing reservoir properties, relatively closed blocks, and optimizing slug combinations, attempts are made to increase throughput from a single surfactant to a carbon dioxide complex throughput. Researchers to sulfonate with organic additives based, finished
