Abstract: In order to discuss the sedimentary characteristics and controlling factors of sublacustrine fans in backbulge zone of foreland basin,based on the cores,analysis assay,well logs and 3D seismic data,combined with the method of "point-line-surface",the characteristics of sublacustrine fan of T Ⅱ oil group of Middle Triassic Karamay Formation in Lunnan area of Tarim Basin were analyzed. The results show that sand-rich sublacustrine fans were developed in the study area, which are mainly composed of gravelly coarse sandstone,conglomeratic sandstone and medium-coarse sandstone,with Bouma sequence vertically developed,and grading bedding,massive bedding as well as deformed bedding could be recognized. In addition,the logging curves show a combination of micro linear dentalization and block or bell shaped. On seismic profiles,they are responded to middlehigh amplitude and high continuity refection or lenticular or short axial refection,and incised sinuous channels are identified on RMS(root-mean-square) amplitude attribute. Meanwhile,three subfacies and five microfacies were recognized,among which feeder channel and levee microfacies were developed in inner fan,braided channel and interchannels were developed in middle fan,and distal source turbidite were developed in outer fan. The sublacustrine fans located below the south slope break belt,with several distinct feeder channels developed,and compared with separated interchannels,the braided channels were continuously distributed. Caused by gravity flows,the sublacustrine fans were formed as a result of that a large amount of sandstone were transported to deepwater environment through feeder channels, and the development of sublacustrine fans were controlled by episodic tectonic activities of foreland basin, paleogeomorphology,and provenance supply. The development of sublacustrine fans was induced by tectonic activities,and the planar distribution characteristics were influenced by paleogeomorphology,with lithology,physical properties,and scale determined by provenance supply.

Key words: sublacustrine fan, backbulge zone, foreland basin, sedimentary characteristics, controlling factors, depositional model, Tarim Basin
