Natural gas production has risen dramatically worldwide since the seventies, and it is estimated that the peak of natural gas production will come at the beginning of 21th century.

    In making the development programmes of the year 2000, one of the important guiding ideologies is to enhance the exploration for natural gas. Natural gas production has risen dramatically worldwide since the seventies, and it is estimated that the peak of natural gas production will come at the beginning of 21th century. An analysis of regional geology conditions indicates that China will be a country rich in gas. This is recognized by multitudinous continental large-scale basins, wide distribution of coal-bearing formations, very large coal resources and deep depressions with large extent. In addition, the exploration of natural gas is fruitful recently. All these confirms that there are vast gas resources in China to be explored widely. But there are some weak links which need to be improved and overcomed in China's natural gas exploration. It is believed that a new stage of natural gas industry will arise in the near future.

    我国是一个富气的国家,陆相大型盆地多,含煤地层多,煤炭储量大,盆地沉陷深,幅度大,并具备了大气田形成的地质条件。近期天然气勘探形势很好,有许多新的发现,说明我国天然气资源丰富,勘探有着广阔的前景。预测华北盆地、陕甘宁盆地、松辽盆地东南部、辽河坳陷南部至辽东湾、濮阳深层和莺歌海盆地等,都是有利的含气区。过去在天然气勘探上还存在一些薄弱环节,今后,应该有计划有步骤地开展天然气的专探。相信在不远的将来,一定会出现一个天然气勘探的高潮,开创天然气工业的新局面。

The main industry reservoir in the dolomite of the Siniansy stsyem. The oldest layer is about 700~ 800 × 106years. It is the largest and oldest gas field which has been found in China so far. It is significant for the study of early organic matter evolution, mineral and energy resources to study out the genesis of gaspool, especially,...

    This paper studies the largest gas field- Weiyuan gas field in Sichuan : basin . There are four gas-bearing layers in the gas pool, i.e. Triassic, Permian, Cambrian and Sinian. The main industry reservoir in the dolomite of the Siniansy stsyem. The oldest layer is about 700~ 800 × 106years. It is the largest and oldest gas field which has been found in China so far. It is significant for the study of early organic matter evolution, mineral and energy resources to study out the genesis of gaspool, especially, to decide whether the source of Sinian gas pool may be relative to precambrian layers.

    本文研究了中国最大的气田——四川威远气田的气体组分和碳、氢、硫、氩、氦同位素组成.其特征如下:(1)震旦纪气藏相对于其它气藏具有高氮(9%),高CO_2+H_2S(5%)和高氦(0.18%),高氩(0.05%)的特征;(2)震旦纪气藏的氩同位素组成为4400—9255,平均7000,显示了很高的年代积累效应.3He/4He比值低为n×10~(-8),这意味着威远气藏中的氦主要来自壳源物质;(3)He/Ar丰度为5.39—6.14,是笔者研究过的天然气中的最低值;(4)N_2/Ar,N_2/He浓度具有较好线性关系;(5)碳、氢、硫、氩同位素丰度比可将三叠纪、二叠纪、寒武纪、震旦纪气藏明显加以区分,证明各自属不同气源.(6)震旦系岩石吸咐烃和储气层气体的C_2/C_3有良好的对比性.因此,笔者认为:震旦系气藏为自生自储.稀有气体不具地幔物质特征,但不排斥有幔源物质加入的可能.

    With respect to source material, maturation, accumulation and flowability, gas is more favorable than oil in forming hydrocarbon deposits. The wide occurrence of basins onland and offshore, abundance of coal resources, rich variety of paleolifts and traps, all favor the formation of giant gas fields However, complicated movement of plate tectonics in China since the late Paleozoic era resulted in poor reservoir properties and less favorable preservation, which can be the reason why no giant gas field is found...

    With respect to source material, maturation, accumulation and flowability, gas is more favorable than oil in forming hydrocarbon deposits. The wide occurrence of basins onland and offshore, abundance of coal resources, rich variety of paleolifts and traps, all favor the formation of giant gas fields However, complicated movement of plate tectonics in China since the late Paleozoic era resulted in poor reservoir properties and less favorable preservation, which can be the reason why no giant gas field is found in China. The author makes the following proposal: (1)pay equal attention to large basins and small basins, (2) lay stress on Carboniferous and Permian, (3)focus on the locations of paleo up lift superimposed with various traps, (4)turn to deep formations with improved geological and physical conditions, (5)explore for non-hydrocarbon gas.

    从生气母质、生气的窗口、聚集环境和流体的活动性等方面比较,天然气比石油具更广泛的成藏条件。中国大陆和海域的盆地特征、丰富的煤炭资源、发现的古隆起和圈闭类型,中国具有形成大气田的地质条件。但由于晚古生代以来中国板块构造复杂的演变,带来了储层物性不好和保藏条件欠佳两个不利因素,故中国至今尚未发现一些大气田。在今后的勘探工作中,作者提出(1)勘探稳定型盆地要与勘探活动型盆地兼顾;(2)选择层位上要注意石炭系和二叠系;(3)选择构造上要重视古隆起和其它圈闭的叠合部位;(4)注意深层中发现储层物性变好的地质和物理条件;(5)适当注意非烃气藏的勘探工作等5个方面为寻找气田的方向。
