摘　　要：胡尖山油田AP区块长7致密油自2010年投入开发以来,定向井表现为单产低,注水见效即见水;水平井虽初期单产高,但存在自然能量开发递减大,注水后多向见水,严重制约着致密油的高效开发。2014年以来该区开展了吞吐采油试验,地层能量得到了有效补充、油井递减得到了减缓,取得了初步成效。论文通过吞吐效果评价及认识,为该区后期扩大开展吞吐采油范围、确保油田持续稳产提供了科学依据。The AP block of Hujianshan oilfield Chang 7 tight oil since 2010 in the development of directional wells is low yield,water flooding, namely water.Horizontal well although early high yield,but the existence of natural energy development decreases,after water injection more see water, seriously restricts the efficient development of tight oil.Since 2014, the production test of huff and puff has been carried out in this area,the formation energy has been effectively supplemented,and the decline of oil wells has been slowed down,and the initial results have been achieved.By evaluating and understanding the effect of huff and puff,the paper provides a scientific basis for expanding the scope of oil production and ensuring sustained and stable oil production in the later stage of this area.
