摘要:
针对渤海W油田注聚目标区因油井转注水而引起的水井与注聚井相互干扰问题,基于典型模型,精细研究了水聚干扰下的驱油动态、影响因素及作用规律。测试了采用调整水聚同驱区域的注水/注聚速度比例、注水/注聚井注入介质互换和水/聚交替注入3种方法对改善水聚干扰驱油效果的影响。W油田的实例应用潜力评估表明,研究成果对于渤海油田聚合物驱方案的顺利实施与调整完善具有借鉴意义。
Abstract:
The water and polymer interaction problem in W Oilfield was obvious due to the water injectors converted from producers and new infilling ones in previous polymer injection well pattern. According to a typical reservoir model, it was carried out studies on dynamic production indexes under water and polymer interaction such as swept area, water cut, oil producing rate, etc., and it was analyzed the influence mechanism of these indexes on oil displacement efficiency. And then it was tested the three improving methods: properly reducing water injection rate in water and polymer interaction area, injected water and polymer interchanging in injectors, and water alternating polymer. A pilot was conducted in W Oilfield for application evaluation. This study results provide critical insights for understanding the polymer and water interaction mechanism and optimization strategies for offshore polymer flooding projects in Bohai Bay.
