Description

Technical Field

[0001] The invention relates to the technical field of petroleum and natural gas engineering, and in particular to an interactive unconventional oil and gas reservoir reservoir physical property evaluation experimental teaching device and method. Background Art

[0002] Unconventional oil and gas reservoirs refer to oil and gas deposits whose characteristics, accumulation mechanisms and mining technologies are different from those of conventional oil and gas reservoirs. They have large resource scales and poor reservoir properties. Generally, the porosity is less than 10%, the permeability is less than 1mD, the resource volume is large but the recovery rate is low, and it is difficult to use conventional methods and technical means for economic exploration and development. Therefore, the evaluation of unconventional resources pays more attention to the evaluation of resource effectiveness, and pays more attention to the recoverability and recoverable reserves of resources.

[0003] In the teaching of petroleum and natural gas engineering courses, the characteristics, physical properties and related evaluation and testing methods of conventional oil and gas reservoirs are taken as the basis and focus, and on this basis, the teaching content related to unconventional oil and gas reservoirs is introduced and expanded. The physical property test of oil and gas reservoirs involves many physical parameters such as porosity, permeability, specific surface area, pore size distribution, microscopic pore structure, etc. In the actual experimental teaching process, due to the lack of simulation operation experiments and virtual simulation teaching materials, students can generally only learn based on the perceptual understanding of textbooks and courseware, and lack the experimental principles, equipment composition and experimental process of the related experiments of unconventional oil and gas reservoir physical property testing. Students, as cognitive subjects, are often in a state of passive acceptance of knowledge throughout the teaching process, and their independent learning of key industry knowledge such as unconventional oil and gas reservoirs has certain blindness and limitations.

[0004] Due to the traditional experimental classroom teaching, it is difficult for students to compare and connect the different physical property parameter testing methods of unconventional oil and gas reservoirs, and they cannot fully master the testing principles and methods of different reservoir physical property parameters within the limited classroom time. Therefore, it is urgent to build an interactive unconventional oil and gas reservoir physical property evaluation experimental teaching device and method. Summary of the invention
