Abstract: The PingHu Tectonic Belt is one of the key point of hydrocarbon exploration and development in the East China Sea, 3D seismic exploration of 7 blocks have been finished, 13 well drilled and 4 fields including the PingHu field discovered in the main body of the area.Combined with the new 3D interpretation results, this paper re-recognized the early discovered part structures.Comprehensive analysis indicated that the reservoir condition is good in the trap among the PingZhong and PingBei fields, which can be predicted as the beneficial hydrocarbon-bearing structures for future drilling, and the PingNan area may be listed in new group of exploration.
