位于科罗拉多州西北部RangelyWeber油区，实施了大型的WAGCO2混相驱。由于成熟的驱油阶段伴随着开采费用的自然增加和产油量的衰减，使得波及提高成为少有的几个能同时缩减开采费用并增加可采储量的策略之一，包括油藏的垂向和面积波及。在过去的10年中推广应用了许多不同的工艺技术以提高油藏的波及效果，真中包括：选择性注入设备＼跨式双封隔器组合＼井网重新定位、挤水泥、泡沫处理、半周段塞大小、同时注入和聚合物处理作业。这些工作都取得了不同程度的成功。买践证明；大排量（10000bbl）的聚合物凝胶处理作业能有效地改善深部油藏，而以往的近井眼作业不能有效地阻止流体进入高渗性基岩中以及波及软弱的裂缝通道内。本文讨论了1997还实施聚合物凝胶处理作业的44口注入井作业效果，并提供了单一的作业实例以及项目经济较差的评价。最后给土了下一个10年期间继续实施的作业效果的模拟和预测的评价。
Located in the RangelyWeber oil zone in northwestern Colorado, a large WAGCO2 hybrid flooding was implemented. As the mature flooding phase is accompanied by a natural increase in production costs and a decline in oil production, wave enhancement has become one of the few strategies that can simultaneously reduce mining costs and increase recoverable reserves, including vertical And the area spreads. In the past 10 years, many different technologies have been widely used to enhance the oil recovery effect. These include selective injection equipment, straddle double packer combination, well pattern repositioning, grouting, foam treatment, half cycle Slug size, simultaneous injection and polymer handling jobs. These efforts have achieved varying degrees of success. It has been proved that the large displacement (10000bbl) polymer gel treatment can effectively improve the deep reservoirs, whereas the previous near-wellbore operation can not effectively prevent the fluid from entering the hypertonic bedrock and inflict weak crack path Inside. This article discusses the effectiveness of 44 injection wells that also performed polymer gel processing operations in 1997 and provides a single example of the operation and a less economical evaluation of the project. Finally, I gave the evaluation of the simulation and prediction of the operational effects that I continued to implement during the next 10 years.
