Li ZongJie, Wang Qinchong. METHOD AND TECHNIQUE FOR PREDICTION OF SUPER-DEEP CARBONATE RESERVOIRS IN NORTH TARIM BASIN[J]. 2002, 23(1): 35-40.DOI: 10.11743/ogg20020107.
The Carbonate reservoirs of Tahe Oilfield in North Tarim are characterized by large buried depth
week seismic reflection signal and high heterogineity.Three methods could be used to predict this kind of reservoirs:1.use seismic horizon flattening technique to restore fossil landform;use seismic attribute parameters to restor fossil water system.Then predict the karst reservoir developed position;2.use the parameters of coherence
amplitude
wave impedance inversion and constrained logging to analyze the validity of the reservoir;3.use pattern recognition technique to predict reservoir's oil and gas potential
including hystogram
2-D cross plot and 3-D cross plot.The practice has proved that the predicted distribution areas of available carbonate reservoirs fit well with the actural ones
