【摘要】 榆树林油田扶扬油层储层类型为低孔特低渗透储层,储量的动用程度很低,同一区块I类探明储量较Ⅲ类探明储量不仅大幅度减少,而且低效井比例增高。对榆树林扶杨油层的探明储量进行了复算,进一步落实了不同渗透率级别储层储量所占的比例以及分布状况;根据渗流机理研究了特低渗透扶杨油层可动用储层渗透率极限,分析了无法动用储量所占的比例。结合该油田自身开发的特点,选择合适的评价方法,对未开发区按储量的可动用状况进行了分类评价,并优选了有动用潜力的区块。更多还原

【Abstract】 Fuyang reservoir has low porosity and ultra low permeability, with low producing degree of reserves. The developed proved reserves are extremely less than the undeveloped proved reserves in same area, and the scale of low producing well is increasing. This paper recalculates the proved reserves of Fuyang reservoir of Yushulin oilfield, determines the scale and distributing status of different permeability level reserves, studies the permeability limit of producing reservoir on ultra low permeable Fuyang reservoir through the research of seepage mechanism, and analyzes the scale of unproductive reserves. Combining the development characteristic of Yushulin oilfield and choosing appropriate evaluation method, it classifies and evaluates the undeveloped areas according to the producing status of reserves, making a best choice of producing potential areas.更多还原
