摘要
夹层的存在影响蒸汽腔的垂向扩展以及泄液,从而影响SAGD的开发效果。根据风城油田重18井区SAGD区J3q3储层夹层的电性、物性特征对其进行了划分,识别出夹层的物质组成,并进一步确定了夹层的分布范围。通过数模研究,分析了不同夹层位置和展布范围对SAGD生产的影响,注汽井上方夹层可导致蒸汽腔垂向发育减缓,注汽井和生产井井间夹层可导致无法形成有效泄液通道。与动态实例结合,证实了井间夹层对生产的影响大于注汽井上方夹层。该研究为SAGD效果分析、井位部署、措施制订等提供了技术支撑。
The presence of interbedding influences the vertical extension and fluid drainage of steam chamber,thereby affecting the development effect of SAGD. Based on the electrical and physical properties of interbedding in J3q3 reservoir,Zone SAGD,Zhong-18 Well Field,Fengcheng Oilfield,it has been classified to identify the compositions and the distribution range of interbedding.Through the research on numerical simulation,analysis has been made to determine the influence of location and extension range of different interbeddings on SAGD production. The interbedding above gas injector may lead to slowing vertical development of steam chamber. The interbedding between gas injector and producer may lead to the failure to form effective path for fluid drainage. Combined with dynamic examples,it is proved that the interbedding between wells have more impact on production than interbedding above gas injector. The research provides technical support for the effect analysis,proposition of well location and measures taken for SAGD.
