Characteristics of Low Resistivity Oil Reservoir in Yanchang Formation Shanbei Triassic System and Its Origin.
Zhang Xiaoli.
There are two kinds of oil
reservoir, which have different characteristics in Yanchang Formation Shanbei Triassic.
They are the normal high resistivity oilreservoir and abnormal low resistivity
oilreservoir. According to the conduction mechanism of rock and its influence factors, the
origin of the low resistivity oil reservoir is analyzed. It is suggested that the formation
of the low resistivity oilreservoir results from lithology, physical property, water
property, oilbearing property and trap type, etc.
