Abstract: Based on the principle of base level cycle change, the data of field outcrop, drilling, logging and seismic stratigraphic slice were used to analyze the sequence structure, river channel composition characteristics under different accommodation spaces and river type conversion model of the second member of Jurassic Shaximiao Formation in Wubaochang area of northeastern Sichuan Basin. The results show that:(1) There are mainly one third-order and three fourth-order base level cycles developed in the second member of Jurassic Shaximiao Formation in Wubaochang area of northeastern Sichuan Basin. Each fourth-order sequence is a thick layered stacked box type sand body under the low accommodation space. With the base level rising, the accommodation space increases, and it transits to a relatively isolated sand body deposition at the top of the sequence.(2) The paleoclimate of the second member of Shaximiao Formation was dry. Due to the near provenance deposition, the sandstone was coarse and the maturity was low, the strong hydrodynamic structure was developed, it was parallel reflection on seismic profile, and the fluvial facies characteristics were obvious. There are many braided river sedimentary systems with discontinuous positive rhythms superimposed on each other in low accommodation space and meandering river sedimentary systems with binary structure in high accommodation space.(3) The fluvial facies strata of the second member of Shaximiao Formation have a "braid curve" transformation law from bottom to top, which is specifically shown as follows:under the low accommodation space, sand bodies are distributed in a large area, and the seismic geomorphology is shown as mutually overlapping braided river channels. When the base level rises rapidly, the accommodation space increases, and the seismic geomorphology shows a relatively isolated meandering river channel.(4) The accommodation space and sediment supply ratio(A/S) is mainly affected by strong tectonic activity and change from warm and humid to hot and dry climate in Daba Mountain provenance area.

Key words: accommodation space and sediment supply ratio, fluvial facies, base level cycle, stratal slice, Shaximiao Formation, Jurassic, Wubaochang area, northeastern Sichuan Basin
