Analysis of Imaging Logging in Ordovician Carbonate Formation

AbstractThe reservoir space types of the Tahe oilfield are various and unevenly distributed with strong heterogeneity, which contain Karst holes, cracks and caves. They also make reserving and penetrating mechanisms and reservoir characteristics complicated. Through a brief analysis of the several kinds of imaging logging data applied in carbonate reservoir evaluation in Tahe oilfield, this paper focus on features of the fractured, dissolved pore and karst cave reservoirs recognized by such data with a comparative analysis. By electric imaging logging data, little difference is found among evaluation of different types of reservoirs and FMI borehole coverage and image quality are relatively high; with acoustic imaging logging data, the borehole coverage is higher, thus, it can give a better evaluation of different types of reservoirs in viscous oil area, however, the resolution is lower, for which, it cannot be used in evaluation of corrosion and dissolved pore reservoir.
