摘　　要：欢127块目前已处于开发中后期,受汽窜、水淹、出砂影响,吞吐效果逐年变差。根据区块自身特点,提出组合吞吐注汽的办法,对于适宜油藏可以使吞吐阶段延长2～4个周期,采收率提高2～3个百分点,对于抑制蒸汽吞吐稠油油藏高周期的产量递减具有重要的现实意义。Huan 127 block is now in the middle and later stage of development. Influenced by steam channeling, water flooding and sand production, the effect of huff and puff is getting worse year by year. According to the characteristics of the block, the steam injection method of combined huff and puff is put forward. For suitable reservoirs, the huff and puff stage can be extended by 2-4 cycles, and the recovery factor will be increased by 2-3 percentage points. It has important practical significance for restraining high cycle production decline of huff and puffheavy oil reservoirs.
