【摘要】 水驱开发油田进入高含水后期和特高含水期阶段,聚合物驱油是油田提高采收率的重要开采技术,而油藏数值模拟技术是油田开发过程中改善油田开发效果的重要技术保障。喇嘛甸油田南中块西部葡Ⅰ1-2油层于2004年7月开始注聚。由于初期编制区块聚驱开发方案时,开展的数值模拟研究是在水驱开发阶段数值模拟基础上,从宏观上模拟了同一聚合物浓度、不同注入模式下的区块聚驱动态变化特征和开采效果,不可能精细模拟到各种措施(诸如整体调剖、层系封堵、压裂、补孔、调速、水驱井代用等)导致单井工作制度变化等综合调整对开采效果产生的影响,因此聚驱数值模拟结果和现场实际效果存在一定偏差。为了更客观、准确地揭示水驱、聚驱油后地下油水运动规律和精细描述剩余油分布状况,为优化编制聚驱综合调整方案和准确编制单井措施方案提供依据,提高综合调整方案的有效率,不断改善聚驱开发效果,开展喇嘛甸油田南中块西部葡Ⅰ1-2油层数值模拟研究无论从理论上还是现场应用上是非常必要的。通过该项目研究,研究出一套适合油田现场实际的聚驱跟踪调整数值模拟技术,确定聚驱方案优化及注采参数的优选方法,在聚驱跟踪现场应用领域具有较高的实用价值,为其它区块和油层的聚驱跟踪调整起到指导和参考作用。更多还原

【Abstract】 The oil development has been in the high water development stage. Polymer flooding is an important technique to improve recovery factor in the oil field, and the technique of numerical modeling is an important technique guarantee to meliorate the effect of development of the field. The PutaohuaⅠ1-2 reservoir was infused polymer at July 2004, in the south west lamadian oil field. At the initial stages of making the block development plan of the polymer, the research of numerical modeling is basis on the numerical model of water driving stage, by macroscopical view, simulate the dynamic change characteristic and exploitation effect of the polymer flooding block at the same polymer concentration and under different infusing mode, it can’t simulate every provision finely (for example: adjust perfectly absorption profile, series block off, break down, perforations adding, adjusting speed, water driving well stay so on ), leading infection of exploitation effect about the integrated adjust eg. the work system of single well. So there is a few difference between the result of polymer numerical modeling and local practice effect. For posting more personality and truly the movement rule of water and oil underground and describing finely the distributing condition of surplus oil after the water and polymer driving. For optimizing the integrated adjust project of polymer flooding and making actually measure project of single well to offer basis, for advance the efficiency of integrated adjust project, for improve the effect of polymer developing continually, it is very important for theory and local application to develop the numerical modeling research of the PutaohuaⅠ1-2 reservoir of Lamadian oil field.Throw the item research, making a suit of numerical modeling technique of the polymer flooding about local practice in the oil field, and confirming the measure of advancing polymer project and choosing the parameter of injection and projection, it has practice value in the local application of the polymer flooding tracking, it offer the guidance and reference for the other block and oil layer of adjusting of polymer flooding tracking.更多还原
