塔河油田超稠油区块受油稠、原油粘温拐点深、下泵深、掺稀混配效果差等因素影响,在机械举升过程中普遍存在异常故障率高、检泵周期短、掺稀比高等问题。本文通过在泵下加长尾管,将掺入点下移至粘温拐点深度以下,同时增长混合油的混合距离,使稀油和稠油混合得更均匀,解决稠油入泵难的问题,达到了节约稀油的效果。现场试验表明:前后不同生产方式应用尾管悬挂装置后效果不同,粘温拐点深度决定尾管下深。 The heavy oil in Tahe Oilfield is affected by factors such as oil thickening, inflexion of crude oil sticking point, deep mixing of lower oil and poor mixing effect. In the process of mechanical lifting, abnormal failure rate is high, pump cycle is short, Doping ratio higher issue. In this paper, by adding a long tail pipe under the pump, the mixing point down to the stick point temperature below the inflection point, while increasing the mixing distance of mixed oil, thin oil and heavy oil mixed more evenly to solve the problem of heavy oil into the pump difficult, Achieved the effect of saving thin oil. Field tests show that the effect of tail pipe suspension is different after different production modes are applied before and after. The depth of sticking temperature inflection point determines the depth of tail pipe.
