随着油气藏类型和井筒结构愈加呈现出多样化和复杂性，要想实现复杂油气藏和复杂井况的油气资源经济有效动用，先进、高效、稳定的提高采收率技术和增产措施至关重要。泡沫因其密度小、黏度高、能有效保护油气层、调剖堵水能力强以及驱油机理完善等性能，在钻完井、固井、储层保护、储层改造和提高采收率等领域都取得了较好的现场应用效果。本文在介绍泡沫相关理论的基础上，归纳总结了近年来泡沫流体在非常规油气藏开发各个领域的室内研究与矿场试验，分析了泡沫流体提高采收率和增产措施的优缺点，并展望其未来发展方向。

As reservoir types and wellbore structures become more diverse and complex，advanced，efficient，and stable EOR techniques and stimulation are critical to achieving cost-effective production of oil and gas resources in complex reservoirs and wells. With its low density，high viscosity，effective protection of oil and gas reservoirs，strong profile control and water plugging ability and perfect oil displacement mechanism，foam has achieved good field application results in drilling and completion， cementing，reservoir protection，reservoir transformation and enhanced oil recovery. Based on the introduction of foam theory，the laboratory studies and field tests of foam fluid in various fields of unconventional oil and gas reservoir development in recent years was summarized，the advantages and disadvantages of enhanced oil recovery and stimulation measures was analyzed，and its future development direction was forecasted.
