哈拉哈塘地区缝洞型碳酸盐岩油藏单井生产特征

缝洞型碳酸盐岩油藏储集体及流体分布的复杂性决定了该类油藏油井开采特征的巨大差异性。通过单井类型划分,可以更好地指导油田的开发生产。由于油井的生产动态在一定程度上反应了不同的储集空间类型,根据单井生产特征可对储集层类型进行划分,建立相应的评价指标及划分标准,并针对性地提出生产措施建议。通过单井实例分析,在动、静态两方面验证了划分方案的准确性与可行性,对其它地区同类型油藏具有一定借鉴意义。

Research on single well production performance for fractured-vuggy carbonate reservoirs

The complexity in reservoir body and fluid distribution in fractured-vuggy carbonate reservoir has resulted in great differences in well production characteristics.Classification of single wells is helpful to oilfield exploitation and production.Since production performance can reflect the type of reservoir space to a certain extent,the production characteristic of single well can be used to classify reservoir types.Corresponding evaluation index and classification standard are established,and suggestions on production measures are put forward accordingly for each type of reservoirs.Case analysis on single wells has verified the accuracy and feasibility of this classification scheme in both dynamic and static aspects.The research result can be referred to by other similar reservoirs.
