Abstract:

In order to explore old reservoir potential, 3-D seismic data and drilling data are integrated and used in reservoir areas are determined: (1) the mini-structures around faults; (2)the structure formed by sealing of fault plane; (3) the blind areas surrounded by faults and (4) the lower part blind areas located not on main stream lines. The potential exploring illustrates that 3-D seismic data has incomparable advantage over 2 -D ones, specially, exploring old reservoir potential will be effectively guided by tight combination of 3-D seismic data and drilling data so as to determine well location.

Key words: old oil/gas bearing region, fault block reservoir, exploring reservoir potential, 3-D seismic data interpretation
