摘要:
随着油田开发进入中后期,储层精细刻画决定了剩余油分布及油田挖潜方向。以Q油田北块砂体为例,针对区域生产动态矛盾,结合新处理高分辨率地震资料,以沉积模式为指导,完成复合砂体内部小层、单砂体级别储层精细对比。依据目标区存在的曲流河砂体叠置关系,建立3种叠置砂体的地震正演模型,明确不同叠置砂体剖面特征;在此基础上结合区域沉积背景,井震、动静结合开展平面储层精细刻画。研究成果指导了油田高含水期注采井网调整及挖潜,部署调整井8口,增加产能550 m3/d。
Abstract:
As the oilfield development progresses to the middle and late stages,the fine characterization of the reservoir determines the distribution of remaining oil and the direction of oilfield potential tapping.Taking the sandbody in the north block of Q Oilfield as an example,the fine correlation of small layers and single-sandbody-level reservoirs in the composite sandbody was completed in view of the contradiction of regional production performance,combined with newly processed high-resolution seismic data,and guided by the sedimentary mode. According to the superimposed relationship of meandering river sandbodies in the target area,the seismic forward modeling of three superimposed sandbodies was established to clarify the profile characteristics of different superimposed sandbodies. On this basis,the precise characterization of the plane reservoir was carried out,combining well-seismic and dynamic static data with the regional sedimentary background. During the high water-cut stage,the results guided the adjustment and potential tapping of the injection-production well pattern. The production capacity was increased by 550 m3/d due to the implementation of eight adjustment wells.
