Abstract

Abstract

Nowadays, a lot of mounded seismic reflections in the Mid-Miocene Meishan Formation were found and attracted the attention of geologists, while the genesises of the mound were various. Combined with the 3D high resolution seismic data and the 2D seismic datum and drilling, this paper aimed at analyzing the characteristics of the mounds. The results show that compared with the weak amplitude channel filled with mudstone in northeast 3D area and the high amplitude channel filled with sandstone in southwest 3D area, the elongated mounds with nearly EW orientaion had mediate amplitude. The channel located between mounds. Wave impedance inversion unravelled that the mounds with inner lower impedance should belong to the scope of mudstone. The inner mound bed with ductile within Meishan Formation were subjected to gravitational spreading, which contributed to developed polygonal faults on the overlying strata with brittle property. Under this circumstance, Meishan Formation was concluded to form in deepwater depositional environment in Mid-Miocene and mounds on the top of Meishan Formation consisted of mudstone. Mounds and channels formed the sag-crest bedform corresponded with channels and mounds above the overlying strata, respectively, which was regarded as the result of bottom current of incision and deposition. This study about the Mid-Miocene mound reflections has guiding significance and can improve the success rate of oil and gas exploration drilling and can reduce oil and gas exploration risk.
