克—百油田是以山麓洪积相为主,平面上和剖面上非均质程度十分严重的砾岩油田,储层孔隙结构复杂,类型多,分选极差。有效渗透率1～200毫达西,油层层间渗透率级差大,两个相邻样品(间隔10～25厘米)渗透率级差为20～50倍。泥质含量大多在10～18％之间,百口泉组最高为10～25％。 面对这样复杂的油藏,能否提高排液速度的问题,尽管从七十年代中期以来做了些
The K-100 oilfield is a conglomerate oilfield mainly characterized by foothills and alluvial facies, with a very high level of inhomogeneity in the plane and the section. The pore structure of the reservoir is complex, with many types and poor sorting. The effective permeability is between 1 and 200 millidarcies, and the difference in permeability between layers is large. The difference in permeability between two adjacent samples (intervals of 10 to 25 cm) is 20 to 50 times. Mostly muddy content is between 10 ~ 18%, Baikouquan up to 10 ~ 25%. In the face of such a complex reservoir, whether to increase the rate of drainage can be achieved, although some have been done since the mid-1970s
