摘　　要：该文介绍了空气泡沫驱油机理、泡沫液配方、试验井组的优选及在百色油田灰岩油藏的现场试验。试验结果表明：对灰岩油藏进行泡沫驱油能达到增油降水的目的。试验井３口，对应受效井４口，一年累增油１９４５ｔ。投入产出比为１∶３．８９，其中西区的投入产出比达到了１∶７．６２，且继续有效。为灰岩油藏提高采收率展示了美好的前景。The paper presents the mechanism of air foam oil displacement, foam liquid formula, testing well group optimization, and field test in calcareous rock of Baise oilfield. The testing results show that the foam flooding for calcareous rock reservoir can increase oil and decrease water productions. There are three testing wells, four benefited wells and cumulative incremental oil 1945t. The ratio of input to output is 1:3.89 and that of west region is 1:7.62, furthermore, it lasted up to now. It shows wonderful prospect for enhancing oil recovery in calcareous rock reservoir
