摘　　要：J131井区克下组油藏于2000年投入蒸汽吞吐开发.主要存在的问题是：（1）吸水层S63和S62,单层吸水严重不均;（2）井组之间吸水剖面差异明显.通过室内实验配方优选,制定出水膨体颗粒＋微凝胶＋弱凝胶＋强凝胶复合段塞体系施工工艺方式.该体系是通过四种不同强度、不同延迟成胶时间等性能的优势互补,可以充分发挥四个段塞的长处.从而最大限度地提高波及体积和驱油效率.2007-2008年进行调剖试验,试验结束后原液量大的油井,液量幅度下降,含水率下降30％左右,而一些低效井产油量平均增加5～13.5 t/d.截止到2008年底,累计增油2 115t.J131 well-blocks in KEXIA of lower reservoir was developed in 2000 as pouring steam. Main problems wer, （1）suction of water absorption layer S6^3 and S6^2 was imbalance, （2） the difference of water injection profile between well groups was markedly. Through the indoor experiment formula optimization, make water bulk granular micro gel ＋weak gel ＋ strong composite gel slug system construction technology. The system is through four different strength and different properties, such as gel time delay of complementary advantages, can give full play to the strengths of the four slug. So as to improve the swept volume and oil displacement efficiency. Profile control experiment was carried out from 2007 to 2008, after the test concentrate large amount of oil wells, fluid volume, the amplitude of the moisture content fell by around 30 %, and some inefficient wells rose by an average of 5-13.5 t/d output. By the end of 2008 and increased 2 115 tons of oil.
