Analysis of carbonate reservoir types by logging data in Tahe oilfield;

Based on the rock core observation,thin section analysis,reservoir physical property analysis,logging and log data,the petrologic types,pore types and their configuration,distribution of porosity and permeability,reservoir types of Cambrian and Ordovician are studied in detail and discussed deeply.

This paper puts forward a method to distinguish reservoir types in carbonate formation based on the electrical conduction efficiency.

Based on the analysis of sequence type and developing models of the lower Tertiary of Raoyang depression, the controlling factors of every types of sequence are analyzed according to its configuration.

There are three kinds of sequence types including alluvial sequence, lacustrine sequence and fluvial sequence that present in Jizhong basin during the syn extensional stage.
