对五个原油样品所作的28次三次注气岩芯驱替试验，确立了其压力／采收率的曲线并与相同样品所做的细管采收率试验进行了比较。油田内S、H和M油藏已经完成或正在进行CO2驱替，F和A油藏考虑分别采用注CO_2和烃气。四个CO2注入系统的结果与细管试验非常相似。表明在MMP（最小混溶压力）下，采收率下降显著。烃气注入系统的采收率随压力下降线性递减。与MMP无关。对短岩芯而言，最好使用外部过渡带发生器。目前已成功地发展了一种阻止大多数过渡带发生器中产生原油再饱和的新方法。
The 28 third-order gas injection core-fueled tests on five crude oil samples established a plot of pressure / recovery and were compared with the thin-tube recovery test conducted for the same sample. Oilfield S, H and M reservoirs have been completed or are undergoing CO2 flooding, F and A reservoirs are considered for injection of CO2 and hydrocarbon gas, respectively. The results of the four CO2 injection systems are very similar to the tube test. It is shown that the recovery rate of MMP decreases significantly under the condition of MMP (minimum miscibility pressure). The recovery of hydrocarbon gas injection system decreases linearly with decreasing pressure. Has nothing to do with MMP. For short cores, it is best to use an external transition band generator. A new method has been successfully developed to prevent the resurfacing of crude oil in most transition zone generators.
