摘要:
油田聚驱后,剩余油分布十分分散,后续水驱是增油的重要阶段,该阶段工作制度及相关技术研究尤其重要。针对常规分析方法存在的不足,引入流线数值模拟方法,分析聚驱过程中流线变化规律,从本质上解释了生产井动态变化的原因。针对某双高油田聚驱后的流线分布特征,将生产井分为流线稳定型、微缩型和紧缩型三类,分别提出了调整策略。研究表明,流线微缩型生产井可通过井网调整来扩大动用区域; 流线紧缩型生产井,可优选周期注水方式来达到稳油控水的目的。同时,流线法可以从本质上解释油藏动态变化原因,从而解决类似双高油田难以提出合理调整策略的问题。
Abstract:
After polymer flooding, the distribution of remaining oil is very scattered. The subsequent water flooding is an important stage for enhancing oil recovery. So it is significant to study on the working system and the correlation techniques for the stage. Aiming at the deficiencies of conventional analytic methods,the streamline numerical simulation method was introduced to analyze the changing rules of streamline in the process of polymer flooding. And then it was explained in essence the performance change of producing wells. According to the distribution characteristics of streamline after polymer flooding for a certain oilfield with high water-cut and high oil recovery rate, the producing wells were divided into three types of streamline: steady, micro-contraction and retrenchment. And then the corresponding adjustment strategies were proposed. The study results indicated that for wells of micro-contraction type streamline, the recoverable area can be expanded by adjusting well pattern, and for wells of retrenchment type streamline, the purpose of stabilizing oil and controlling water can be obtained by the periodic water injection mode. Meanwhile, the cause of reservoir performance change can be explained by the streamline method in essence. Thus the reasonable adjustment strategy can be proposed for similar oilfields with high water-cut and high oil recovery rate.
