Abstract:

With the progress of theory and technology and the growth of demand for the gas and oil resources，deep carbonate oil and gas reservoir is becoming the important substitute area for exploration of the oil and gas basins. The research of deep petroleum exploration is focusing on the mechanism of carbonates reservoir property evolution. This thesis systematically summarizes the latest research progress and examples in the deep oil and gas fields both in China and abroad. It expounds the key scientific issues of formation and distribution of high quality carbonates reservoirs, such as changes in porosity with depth, change in porosity associated with dolomitization, fluidrock interactions, porosity related to tectonic activities and basin hydrology, etc.

Key words:  deep, high quality reservoirs, carbonate rocks, , dolostone, , fluidrock interactions
