蒸汽吞吐是稠油、超稠油主要的开采方式,在开采过程中,由于隔层不发育、层间存在渗透率差异以及蒸汽超覆等原因的影响,注汽时,高渗透层为强吸汽层,低渗透层为弱吸汽层,甚至不吸汽,随着蒸汽吞吐轮次的增加,进一步会出现井间汽窜干扰现象,大大地降低了蒸汽吞吐效果。本文论述了汽窜产生的原因及造成危害并介绍了如何借助有效的工艺治理汽窜的方法及取得的效果。 Steam huff and puff is the main method of heavy oil and heavy oil exploitation. During the mining process, due to the impermeable interlayer, the difference of permeability between layers and the influence of steam overrun, The vapor layer and the low permeability layer are weakly vapor-absorbing layers, and do not even suck the steam. With the increase of the steam huff and puff, there is a further phenomenon that the gas crosses the well and greatly reduces the steam huff and puff effect. This article discusses the causes of gas steaming and its harmfulness, and introduces how to treat the gas steaming with effective technology and the results obtained.
