| 摘 要： | 南海北部边缘盆地油气地质现象丰富多彩,天然气成因类型及分布规律复杂。根据该区天然气勘探及研究程度,迄今为止勘探所发现烃类天然气可划分为生物气及生物-低熟过渡带气（亚生物气）、成熟-高熟油型气及煤型气以及高熟-过熟天然气等3大成因类型;非烃天然气CO2可划分为壳源型（有机/无机）、壳幔混合型及幔源型等3型4类。生物气及亚生物气在莺—琼盆地及珠江口盆地浅层广泛分布,气源来自上新统及第四系海相沉积;成熟油型气主要分布于北部湾、琼东南东北部及珠江口盆地,气源来自始新统中深湖相偏腐泥型烃源岩;成熟-高熟煤型气及高熟-过熟天然气,则主要展布于莺—琼盆地及珠江口盆地部分地区,前者气源主要由渐新统煤系和中新统海相偏腐殖型烃源岩所供给,后者气源则来自不同类型高熟-过熟烃源岩。CO2则主要富集于莺歌海盆地泥底辟带浅层及琼东南盆地东部和珠江口盆地部分区域,气源分别来自受泥底辟热流体活动影响强烈的中新统海相含钙砂泥岩和深部地幔活动。

| Abstract: | The phenomena of petroleum geology are rich and colorful in marginal basins of the northern South China Sea. The genetic types and distribution of natural gas are complex. Based on the previous research and exploration, the discovered natural gas can be divided into three types: biogenic and sub-biogenic gas, normal and high-mature petroliferous gas and coal-related gas, high and over-mature natural gas. There are also three types of non-hydrocarbon gas (CO2), which are crust-derived type, mantle-derived ty... |
