渤海N油田普通稠油多元热流体驱可行性研究

Feasibility study of multiple thermal fluid displacement of conventional heavy oil in Bohai N oilfield

  • 摘要: 渤海N油田为我国海上一典型的薄互层普通稠油油藏,自2008年投入多元热流体吞吐开发,取得了显著的增产效果,但随着吞吐开采的进行,油藏压力下降、边水突进等问题逐渐显现,周期产量递减快。为提高采收率,针对油藏特点,从多元热流体驱油机理、油藏适应性、工艺参数等方面,对多元热流体驱可行性进行了系统分析研究,结果表明,采用多元热流体驱替开发可在吞吐开发基础上提高采出程度14.13%。

     

    Abstract: Bohai N oilfield is a typical conventional offshore heavy oil reservoir.Since multiple thermal fluid steam stimulation in 2008,remarkable stimulation effect has been obtained.However,with the process of steam stimulation,problems appeared gradually,such as reduced reservoir pressure,edge water breakthrough and quick cycle production decline.In order to enhance recovery ratio,in view of reservoir characteristics,systematic analysis of the multiple thermal fluid displacement feasibility has been carried out from the aspects of the multiple thermal fluid oil displacement mechanism,adaptability,process parameters,etc.The results indicate based on steam stimulation development the multiple thermal fluid displacement development can improve recovery degree of 14.13%.
