In order to meet the needs of oil and gas geological research and production, the Wuxi Petroleum Geology Research Institute of the Petroleum Exploration and Development Research Institute has developed a new hot-pressure simulation tester by modifying the heating system and automatic control system of the original conventional hot-pressure simulation tester. In the experimental geological application, the accuracy of the temperature control and temperature measurement of the simulator is improved, and the test results are more accurate and reliable.
Compared with the original simulator, the new simulator has been greatly improved in the following aspects: First, in the aspect of heat conduction, automatic temperature control is realized to ensure that the temperature in the kettle is consistent when the temperature is high and the temperature is constant. The simulation sample is consistent with the evolution of its products. Secondly, in terms of temperature control, by using the external temperature control and the internal temperature control method, the over-temperature phenomenon that may exist in the original instrument is completely avoided. The third is to reform the vacuum pump circuit. The automatic conversion between vacuuming and nitrogen filling is realized, and the operation is more convenient.
According to reports, the hot rock simulation test of source rock has been widely used in oil and gas exploration, especially in the study of organic matter evolution characteristics, oil and gas source comparison, source recourse and hydrocarbon generation mechanism and hydrocarbon migration. The use of hot-pressure simulation of source rock has given it unique results and rich information.
The successful development of the new conventional hot-pressure simulation tester is not only conducive to the popularization and application of this test method, but also because the simulation tester has the characteristics of accurately collecting and calculating the carbon number of liquid hydrocarbons from 6 to 14 fractions. It is of great theoretical significance to understand the hydrocarbon generation pattern of source rocks and to understand the geochemical change law of this fraction and the quantitative evaluation of the oil layer.
