On the basis of meticulous analysis of sedimentary characteristics in Linnan sub depression, a series of description techniques for sandstone lithologic oil reservoirs are proposed which include recognition techniques of lithosome in undrilled areas, calibration and fine description techniques of lithosome.

Reservoir sedimentary characteristics and heterogeneity of block Cao 4,member 4 of Shahejie formation in Lean Oilfield;

Mesozoic sedimentary characteristics and tectonic evolution in the eastern part of the Qiangtang basin;

Sedimentary characteristics of the shallow Jurassic braided river delta,the Junggar Basin;

Tertiary sedimentary features and environment of the Lanzhou-Minhe basin;

This paper deals with the sedimentary features of the Mesozoic Fanjiatang coal-bearing strata in the southwestern part of Wuwei county in terms of the composition of rocks,the texture and structure of sediments and fossils Combined with logging curves the early, middle and late periods of sedimentary environment are delimited and coal accumulation law is conclude

Fan delta sedimentary features and its controls over subtle hydrocarbon reservoirs of Liu-1 Member in Weixinan sag;

On the basis of drilling geology, core analysis and production test data, this paper studies the sedimentary feature and controlling factors of volcanic reservoirs in Kongdian formation of Gaoqing oilfield through measures such as log constrained inversion.

To gain a clear idea of the sedimentary environment and its sedimentary feature of a sand body is the basis and key to understanding the heterogeneity, evaluating the exploitation effect and making further adjustment.
