摘要
The lake basin Kongdian Period in Kongnan area, Huanghua Depression is continental rift-faulted basin, aiming at this characteristic, taking continental sequence stratigraphy theory and technology as guide, on the basis of sufficiently using core, well logging and seismic data, sequence boundary and system tract boundary are identified. One second-order sequence, four third-order sequences and twelve system tracts were distinguished in Kongdian Formation. Afterwards, through analysis of tectonic-sequence stratigrahy, isochronal tectonic-sequence strata framework of Kongdian Formation, Eogene system was built to realize the sequence strata comparison of Kongnan area. Finally, the combination pattern of source rock, reservoir and cap rock were analyzed, and favorable oil & gas bearing belts were predicted.This provides a new series of study clue for hydrocarbon exploration and development in Kongnan area.
