Studying on a river-course-style lake,Wujindan lake in Xinghua, the author collect late holocene deposit samples 20-280cm in the means of undergroumd, analyse these samples observation with eyes,grain size,clay mineral observation bytx-ray,mineral magnetic,the content of B, gromdomg samples, then but forward the marks of floodwater deposit in the samples.

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.

According to the analysis of a large number of rock thin-sections and cast thin-sections,the depositional features,pore structure and rock physical properties of clastic rocks in Yanchang Formation,Triassic system,Changwu Region,Erdos Basin has been researched.

Aim In order to find out depositional feature and distribution law.

Based on the analysis of sealing core drilling and log analysis, the reservoir type of Sa-0 reservoir in Duanxi of Bei-1 Area in Daqing oil field is identified and the depositional environment and depositional feature of Sa-0 member are studied, the physical property parameters of this reservoir are determined.
