With the continuous development, the remaining oil and gas resources are gradually decreasing, and the demand for energy is growing. Unconventional oil and gas, as an important replacement resource, have begun to draw high attention around the world. As an important part of unconventional oil and gas resources, tight oil plays a crucial role in the global energy, and has achieved commercial development in many countries. The United States has discovered nearly 20 tight oil basins, as well as multiple pay formations such as Bakken, Barnett, and Woodford. In addition, Canada, Argentina, Ecuador, the United Kingdom and Russia, etc., have also achieved breakthroughs in tight oil exploration
[1-2]. In fact, the exploration and development of tight oil in China also has broad prospects. Many basins have developed numerous types of tight oil reservoirs, such as tight sandstone, tight carbonate rock, and tight mixed rock found in basins such as Ordos, Songliao, Sichuan, Bohai Bay, Qaidam, Junggar, Tuha, and Santanghu
[3⇓⇓-6]. China has gone through more than ten years of continuous exploration and development of tight oil, from the exploration stage of tight oil concept and technology, industrial testing and trial production stage, to scale discovery and development and production stage
[7]. Significant progress has been made in geological theory innovation, geological understanding, and engineering technology. However, with poor physical properties, low abundance, and low natural productivity, the exploration and development of tight oil reservoirs are often not as expected. It is urgent to obtain new knowledge and develop new technologies to promote significant breakthroughs and rapid development in tight oil exploration and development.
