In response to the growing demands of oil and gas geological research and production, the Wuxi Petroleum Geology Research Institute, part of the Petroleum Exploration and Development Research Institute, has developed an advanced hot-pressure simulation tester. This new system is an upgraded version of the conventional model, featuring significant improvements in both the heating and automatic control systems. These modifications have enhanced the accuracy of temperature control and measurement during experiments, resulting in more reliable and precise test outcomes.
Compared to the original simulator, the new model has seen substantial improvements in several key areas. First, in terms of heat conduction, the system now supports automatic temperature control, ensuring uniform heating inside the chamber, especially at high temperatures where stability is crucial. This allows the simulated samples to closely mimic the actual evolution of their hydrocarbon products. Second, the temperature control mechanism has been refined by integrating both external and internal control methods, effectively eliminating the risk of overheating that was present in earlier models. Third, the vacuum pump circuit has been redesigned to enable automatic switching between vacuuming and nitrogen filling, making the operation more efficient and user-friendly.
According to industry reports, hot rock simulation tests on source rocks have become a vital tool in oil and gas exploration. They are widely used in studying the evolution of organic matter, comparing oil and gas sources, identifying source rocks, and analyzing hydrocarbon generation mechanisms as well as migration patterns. The application of these simulations has provided unique insights and valuable data for researchers.
The successful development of this new conventional hot-pressure simulation tester not only promotes the broader adoption of this testing method but also brings significant theoretical value. With its ability to accurately collect and calculate carbon numbers of liquid hydrocarbons across 6 to 14 fractions, it plays a critical role in understanding the hydrocarbon generation patterns of source rocks. It also aids in analyzing the geochemical behavior of these fractions and contributes to the quantitative assessment of oil reservoirs. This advancement marks a meaningful step forward in the field of petroleum geology.
