In this paper,a new model for evaluating the regional water resources development and utilization is built up based on set pair analysis,and the model is applied in evaluation of water resources development and utilization in Hanzhong basin.

In this paper,a general model of regional water resources development and utilization is established and the stage of water resources development in the plain area of Hanzhong Basin is determined by fuzzy overall appraisal model.

Characteristics of seismicity in Hanzhong and Ankang basin;

Diagenesis of anhedritite in the Cretaceous reservoir and its influence on the hydrocarbon distribution in southeast Jianghan Basin;

Exploration potential contrast of non-sandstone reservoirs within salt-layers between Shashi and Qianjiang Formations,Jianghan Basin;

Characteristics of pore structures and oil production potential of sandstone reservoir of Paleogene Xingouzui Formation in Jianghan Basin;

Based on the distribution characteristics of proven oil field reserves size and the changing trend of oil yield and discovery rate per exploration well over the years in the Qianjiang Sag,the Jianghan Basin,three different kinds of statistic methods such as pool size sequence,Weng's life cycle and exploration benefit method have been chosen in the paper.

Nonsandstone reservoirs between salt beds of Qianjiang Formation in the Qianjiang Sag of the Jianghan Basin are mainly composed of dolomicrite,glauberite rock,mudstone and their peperite.

The bulk rock analysis technology of organic petrology was used in this paper to systematically study the maceral composition, hydrocarbon generating components and organic thermal evolution of the Lower Tertiary source rock in the Jianghan Basin.

The Central Yunnan Basin is a Mesozoic,Cenozoic basin was formed in the long-term uplifted Sichuan-Yunnan old continental nucleus(customary Kangdian old land) after acutely subsided during Late Indo-Chinese Epoch.
