本文在剖析我国含气盆地的地质特征之后,综合国内外资料,对天然气的分布规律进行了分析,认为在富气盆地中若发现一个气田就预示着可能发现一个含气区;在油气共存盆地中油气在横向上按不同位置富存,纵向上石油往往居中,天然气位其上、下部。据此,对我国找气的有利地区和层位提出了宏观的看法。 After analyzing the geological characteristics of gas-bearing basins in China, the dissertation analyzes the distribution of natural gas based on domestic and international data. It is suggested that if a gas field is found in a gas-rich basin, a gas-bearing area may be found. In the horizontal direction, oil and gas are enriched in different locations, and oil is often centered in the vertical direction, with the upper and lower natural gas levels. Based on this, a macroscopic view is put forward on the favorable regions and strata in China for looking for gas.
