摘　　要：随着低渗透稀油油藏的储量比例逐年增加,注空气驱油技术越来越被人们所关注,然而空气驱并不适合所有的低渗透油藏。为了增加注空气开发低渗透稀油油藏的成功性,在调研国内外油田高压注空气、空气泡沫驱以及部分稀油注空气点火现场试验的基础上,总结了空气驱开发低渗透油藏的实例经验及油藏参数,对比分析了不同注入方式的空气驱开发低渗透稀油油藏的适用性以及长庆低渗透油田空气驱开发的潜力,提出了一套采用不同空气驱注入方式开发不同参数低渗透稀油油藏的参考方案,为一段时期内开发低渗透稀油油藏提供了借鉴作用和依据。As mosure that the air flooding technique can be more effectively used for low-permeability thin oil reservoirs, field tests on high-pressure air injection, air-foam flooding, and thin oil ignition by air injection in some oilfields in China and abroad were investigated. On this basis, experience in air flooding for low-permeability thin oil reservoirs and reservoir parameters were collected, and comparative analyses were made on the applicability of air flooding with different injection modes to low-permeability thin oil reservoirs and the potential of air flooding for the low-permeability Changqing Oilfield. Finally, a development program by using air flooding with different injection modes was proposed for low-permeability thin oil reservoirs with different parameters. This program can serve as reference and basis for the future development of low-permeability thin oil reservoirs.
