Abstract:
Plentiful information from oil-bearing core samples with tension fractures wrer collected from Hua-3 well at the extended line of high production fractural well Quan 5925-3 and Quan 5915 of Xiasiwan oil Field. Analysis to crude oil shows that oil from high production fractural well has very low freezing with low hydrocarbon. But the crude oil of adjacent normal production well come form the same sorce as high production fractural well but is different in nature. This shows that these high production fractural wells have a same geological process of forming oil reservoir. This kind of oil reservoir is named Xiasiwan-style lithological-closed fracture oil reservoir.
