Abstract
This paper deals with the Paleogene low porosity and permeability oil and gas reservoirs in the Wenchang A Depression of the Pearl River Mouth Basin in northern South China Sea.The aim of the program is to test various methods for gas reservoir identification and evaluation under complex geological conditions.At the same time,we established the interpretation models using gas logging data in order to identify the condensate gas and distilled oil effectively.Results show that the methods we adopted are quite effective in identification and evaluation of liquid.It improved the geological interpretation of logging data and could be promoted to other oilfield for application and reference.
