    摘要:

    河间油田东三段发育湖泊滩坝沉积并形成了富集性砂岩油藏。滩坝砂岩油藏的水驱油状况主 要受渗透率影响,而渗透率又受砂体相带的控制。在近岸砂坝发育地区,水淹面积和水淹厚度 较大。远离近岸区,水淹厚度较小,水淹面积不连续。油层内水淹状况主要受沉积层序的韵律 性质控制。

    Abstract:

    Lake beach and bar deposits are well developed in the third member of the Dongying Formation (Dongsan Member), Hejian oilfield. Bar sandbodies form prolific oil reservoirs. The water displacing of bar reservoirs is mainly affected by permeability, which is in turn controlled by sandbody microfacies. Nearshore bar reservoirs display a laterally extensive wateredout area and a great wateredout thickness. Basinward lakeshore sheet sandbodies display a relatively small wateredout thickness and a discontinuous wateredout area. The wateredout characteristics within individual oilbeds are controlled mainly by the rhythmicity of sedimentary sequences.
