New Ways to Study Oil-gas Reservoirs

With extensive conducting of glotal petroleum exploration and development as well as developing study of geologic theories, people begin to pay more and more attention to studies of oil-gas reservoirs. It has become a new study direction to studies physical properties and space features of oil-gas reservoirs from different angles and to set up a reservoir-geology model by studies of outcrop reservoir and downhole geology. Now, reservoir sedimentology has been developing from pure theory to application and the interpretation and prediction of oil-gas reservoirs go from qualitative to quanhtative ways. The paper tells about the study trend, types and geochemistry of China's reservoirs.
