摘要
Abstract
The reservoir of low-middle Ordovician in Shunxi block of Tarim Basin is buried deeply, and has strong heterogeneity because of developed cave and fractures. But the scale of cave and fracture is small. and the response of well and seismic is complex. There is no apparent string reflection, so the reservoir prediction is difficult. Impedance inversion in Ordovician reservoir is comprehensive utilization of geology, seismic and log data based on seismic reflection features and petrophysics analysis. It can help to find the low impedance in favorable area which may develop cave and fracture. By this method, we can recognize the honeycomb small cave and fracture which do not enough to form string reflection. Then combined with seismic amplitude attribute and synthetic seismogram analysis, we could predict the distribution range and thickness of favorable reservoir in Shunxi block, and provide the basis for selection of exploration target.关键词
