摘要
针对锦16二元驱区块转驱前油藏非均质性严重,转驱后窜聚现象较为严重,聚合物污染物堵塞等问题日益突出,开展了化学调控关键技术的研究与现场应用。现场试验表明,该技术可有效改善油藏非均质性、控制窜聚现象、解除聚合物污染物堵塞等问题;实施了锦16二元驱化学调控技术45井次,均取得了较好的增油效果;截止2016年底,累计增油28 746.5 t。
In consideration of severe heterogeneity of oil reservoir before switching to the application of binary flooding system, severe crossflow after switching to the application of binary flooding system and ever- increasing blocking caused by polymer contaminant, the research on key chemical control technology and the field application of the key chemical control technology were carried out. The results of field test have shown that this technology can reduce the heterogeneity of oil reservoir effectively, control crossflow and eliminate the problem of blocking caused by polymer contaminant. This chemical control technology of binary flooding system has been used for 45 well-times in Jin 16 Block, and good oil production effect has been achieved with the accumulative oil production of 28 746.5 t by the end of 2016.
