The characteristics of origin of coal-formed gas and Oil-formed gas are emphatically discu-ssed in this paper, including the types, evolution and hydrocarbon-generating ratio of the kerogen of coal-formed gas(Oil). By use of these indicators such as the components and isotopes of the natural gas, the properties of the associated light-Oil, the organic enclosures and the solid bitumen, the types of natural gas are distinguished and evaluated.

From a discussion of the index of natural gas type (the C isotope series of source rock of natural gas and crude oil,the C isotope of CH_4 and the H iso- tope,the Hg concentration),maturity index (ratio of normal and isomeric alkene),age index (Ar isotope),it is concluded that the natural gas from we- ll Shacan No.2 is petroliferous gas which came from sapropelic type kerogen of the marine source rock,i,e.,the carboniforous and Permian with relativ- ely high maturity.From a correlation of organic geochemical parameters of crude oil and extracted material of source rock and from a correlation of oil field water and the concentrated sea water,the same conclusion can be drawn. It is also proved that crude oil and natural gas are of the same source.The conditions of petroleum geology demonstrates that marine facies Paleozoic, especially,Carboniferous and Permian should be the source rock of oil and gas of well Shacan No.2.

本文通过对天然气类型指标(天然气和原油、源岩的碳同位素系列、甲烷碳同位素、氢同位素和汞含量)、成熟度指标(正异构体比值)和年代指标(氩同位素)的讨论,认为塔里木盆地沙参2井天然气是来自海相源岩腐泥型母质的油型气,气源层为成熟度较高的石炭-二叠系。通过原油与油气源岩地化资料的研究,以及油田水与浓缩海水对比,结论与天然气资料一致,因而油气可能是同源的。从石油地质条件分析,海相古生界作为油气源层是有条件的,石炭-二叠系可能性最大。

Systematic classification for natural gases is not only a foundation for development of natural gas geological theory, but also very siginificant in exploration of natural gases.

Systematic classification for natural gases is not only a foundation for development of natural gas geological theory, but also very siginificant in exploration of natural gases. Based on a great deal of geological and geochemical data obtained from many years of academic research of our group and others, a new classification for natural gases was put forward under the guidence of "multi-source complex and multi-stage continuity". In this classification, natural gases were classified into the biogenic and abiogenic substantially,the biogenic natural gas was further divided into oil type gas and coal type gas according to its source organic matter.Natural gases were also classified dynamically as microbial gas, biothermo-catalytic transitional gas, thermo-catalytic decompositional gas, and high temperature decomposition gas. Different types of natural gases often show different geochemical behavoirs for the reason of variation in organic input, source rocks and thermal maturity. These geochemical properties provide indicators for classification of natural gases. The indicators include chemical compositional related ones: CH4 Index,C1 /C1-5, C2+, C2/C3,and Hg abundance; isotopic compositional ones: δ13C1, δ13C2,δ13C3,δ13C4, δ13Cco2,δDCH4, 3He/4He, 40 Ar/36 Ar; the companying liquid hydrocarbon indices:paraffin index,heptane index, alkane/aromatics index; and their internal relations.
