As the world’s deep water oil and gas exploration continue to strengthen, the deep-water basin has increasingly become the new areas to gain growth in oil and gas reserves. The deep-sea oil and gas exploration has developed the inevitable challenges. Therefore, to make related research about the deep exploration and development in particular characteristic of the reservoir is a necessary requirement to find deep water oil and gas and also the direction of ocean exploration. Pearl River Mouth Basin is a major basin in China’s offshore oil and gas basins with low level of exploration and the lacking comprehensive research on the variation law and influencing factors of reservoir properties. Based on reservoir property data, two secondary porosity zones can be found in the Tertiary reservoirs, Baiyun Sag, mainly in the 2 750～3 800 m and 3 500～4 600 m. After comprehensively analyzing various geological factors, the model which describes the organic acids forming secondary porosity can be summed up as "production, transportation, matching, and dissolution."
