A mixed- controlled clastic shoreline system is a composite clasolite sedimentary system developed in the clastic shoreline zone and controlled by hybrid hydrodynamics, which in turn is affected by river, wave and tidal action. During Silurian, Devonian and Carboniferous periods, under the control of regional tectonics, provenance, paleogeomorphology, sea level change and coastal mixed hydrodynamic conditions, there developed an onshore composite clasolite sedimentary system controlled by braided river, tidal and wave interaction in the Shaya uplift area of the Tarim basin. Based on outcrop, drilling and logging data, a systematic study has been carried out in the Shaya uplift area, including Silurian- Devonian- Carboniferous sedimentary sequence, sedimentary facies and sedimentary model. The sedimentology models of the composite sedimentary system are established indicate that: ① the bay system controlled by wave- tidal developed during Silurian- Devonian; ② a platform- evaporative lagoon- tidal flat system developed in the Early Carboniferous Bachu Formation; ③ a fluvial- wave- tidal influenced delta depositional system developed during the period of the Early Carboniferous Kalashayi Formation. The shoreland sand bodies of the Lower Silurian Kalpintage Formation, the Upper Devonian Donghetang Formation, and the braided river delta sand- bodies of the Lower Carboniferous Kalashayi Formation, which are widely distributed in a large area in northern Tarim basin, were all reformed by tidal and wave action in different degrees. The sand bodies of the high sinuosity braided river alluvial plain developed in the early stage, of which braided river delta front, and subaqueous distributary channel etc., were all inherited, superimposed and reformed by tidal and wave action. The reformed sand bodies of tidal channel, mouth bar, and onshore beach bar, which improved significantly in physical properties, have become favorable zones for the development of the high quality reservoirs. Significant breakthrough has been made in oil and gas exploration, in a favorable target area and strategic replacement area for oil and gas exploration in the future. The depositional models in study area will become theoretical basis for oil and gas exploration of Paleozoic clastic rock reservoirs in the northern Tarim basin.
