TL;DR: In this paper, the genetic type, source and charging history of natural gas in the Yulin gas field in the Ordos Basin have been studied by combining the carbon isotopic composition of the natural gas and geochemical characteristics of light hydrocarbons with carbon isotope fractionation model results and fluid inclusion analysis.

TL;DR: In 2018, the cumulative proved gas reserves of the 72 large gas fields had amounted to 124504×108 m3, accounting for 75% of the total national gas reserves (16.7×1012 m3).

TL;DR: In this paper, the meaning of diffusive concentration in the diffusive volume calculation must be in line with that in the diffusion coefficient measurement during the process of diffusion volume calculation, and some influencing factors are different for the natural gas diffusion coefficients measured by these three methods.

TL;DR: Zhang et al. as mentioned in this paper carried out the study of the properties and characteristics of the fluid, and found the changes of natural gas components and carbon isotope which confirm the accumulation of water-soluble gas with degasification, namely, such accumulation far away from gas source features high methane, high drying factor, high ratio of isoalkane to normal paraffin hydrocarbons, and heavy carbon isotopes in methane and ethane.

TL;DR: In this paper, the major gas generation peak of oil-cracked gas kitchen is determined by study on the gas generation timing of dispersed liquid hydrocarbons inside and outside source rock and ancient oil reservoirs, and the factors affecting the gas generator timing.
