Abstract
Aer Sag is characterized by middle-low-porosity, middle-low-permeability in Erlian oilfield, so, reservoir classification and productivity evaluation are limited by conventional log interpretation. In log practice, conventional log interpretation is only used to qualitatively evaluate the reservoir. According to NMR core analysis, based on digital core technology, obtained are permeability, porosity, oil saturation ratio, water saturation ratio, pore structure index,S1,S2 and S3 of rock by analyzing T2 distributions. Then, evaluated are core pore structure types, reservoir types and productivity. Combining with oil saturation parameters, the reservoir fluid properties can be determined. The digital core technology has better log application effects in Aer Sag of Erlian oilfield.关键词
