摘要：

Nanotechnology plays an important role in the study of microscopic pore structure characterization and hydrocarbon accumulation in unconventional oil and gas tight reservoirs. This paper takes the tight oil reservoir of Permian Lucaogou Formation Jimsar sag in eastern Junggar basin as an example, comprehensively using high pressure mercury analysis, field emission scanning electron microscope (SEM) and nano CT scanning analysis technology to study micronano pore characteristics and structure of Lucaogou Formation tight oil reservoir in Jimsar sag. In addition, the occurrence state of crude in nanopores is analyzed combined with macro and micro characteristics. The results show that nanopore space is one of the main reservoir spaces in the Permian Lucaogou Formation tight oil reservoir in Jimsar sag of Junggar basin. On the whole, the main reservoir pore structure is micron and nano level, showing the characteristics of micron and nano pore throat. Nanopores are generally oil-bearing, and exist mostly in the adsorption state, which changes the traditiongal cognition that micron pore is the only microscopic pore in reservoir. It is the development direction of the future petroleum industry. © 2018, Editorial Department of Earth Science. All right reserved.
