注水水质造成油层损害的评价技术

EVALUATION TECHNOLOGY OF FORMATION DAMAGE CAUSED BY THE QUALITY OF FLOODING WATER

    摘要
  • 摘要: 研究了注水水质造成油层损害的评价技术,分析了注水过程中因水质不合格可能引起油层损害的主要机制,给出各项损害因素引起的表皮系数的具体计算方法,并以利津油田为例,进行油田注水水质引起油层损害的情况分析。结果表明,利津油田目前注水引起的地层损害严重,损害程度较大的注水层段主要是固相损害,潜在损害机制的影响相对较小。

     

    Abstract: The evaluation technology of formation damage causing by the quality of flooding water was studied, and the main mechanism of the causing in the process of water injection was analyzed. The calculating method of skin factor, brought by each damage factor, was put forward. Take Lijin Oilfield as an example, the situation about formation damage was analyzed. It shows that the formation damage caused by water flooding in Lijin Oilfield is very severity, which damage mechanism is mainly brought by solid phase. The effect of latency mechanism in Lijin Oilfield is smaller.
