Developmental mechanism of advantageous Xixiangchi Group reservoirs in Leshan-Longnüsi palaeohigh;

Reservoir characteristics and oil-bearing characters of the carbonate reservoir beds in the pre-salt sediments of Pre-Caspian Basin;

Two extreme modes of reservoir sedimentation: Active rift and passive rift;

In view of the shortage of theory of petroleum genesis, this paper proposes a new theory of petroleum genesis, which considers that hydrocarbons originate from source bed and form within the reservoir bed.

There are four sets of major reservoir beds, and the structures show belt-like distribution.

The solutiontype secondary pore is one of the most important types of pores in clastic reservoirs.

Based on the introduction of structure and formation characteristics,this paper emphasizes on the basic elements of petroleum system such as generating rocks,reservoirs,traps,and migration mediums.

The Jianshan structure is located at the western end of Liping depression in the Qaidam Basin,where gas reservoirs are mainly distributed in the Neogene Xiayoushashan Fm,the Shangganchaigou Fm and the Paleogene Upper Xiaganchaigou Fm.

Comprehensive analysis of the Jurassic clastic reservoir rocks in the Qiangtang Basin,northern Xizang;

Taking Dagang Zaonan oilfield as an example and selecting the parameters of sedimentation and diagenesis,the five types of petrophysical facies featuring the reservoir rocks in this studied area are given by this method.

The present paper, referenced to the previous data, gives an overview of the lacustrine carbonate rocks in China on the basis of rock types, distribution, facies models, reservoir rocks and source rocks.
