【摘要】 开展了大庆油田萨中地区过渡带天然岩心的室内压汞实验,研究发现:该地区的储层孔隙度较高,渗透率大小分布不均匀,岩石孔道分布不集中,分选性较差,储层的非均质性强,孔隙的迂回程度较大,储层孔喉的有效性较好,孔隙半径集中在10.498～10.528μm,储层的主要渗流通道为1.60～6.30μm的孔道,孔隙分布曲线为平缓或多峰曲线,储层的储集性能较好.该结果为萨中过渡带的进一步挖潜和增产、增注以及预防套管损坏提供了依据.更多还原

【Abstract】 By researching the data of pressing the mercury experiments on natural core samples of transitional zone of Sartu central area in Daqing oil field, we have found that the reservoir porosity is high, the distribution of permeability is not equal, the distribution of rock pore is not concentrated, the reservoir is not homogeneous, the rock pore is seriously circumbendibus but has high validity, the pore radius are 10.498～10.528, the main channel radius are 1.6～6.3. The research provides a light for deep potentiality transitional zone of Sartu central area in Daqing oil field.更多还原
