ANALYSIS OF DIAMONDOID HYDROCARBONS IN NATURAL GAS AND ITS APPLICATION TO YING QIONG BASIN

The diamondoid hydrocarbons in natural gas were detected by technique of heavy hydrocarbon concentration of natural gas and MID/GC/MS analysis.On basis of measured diamantane and vitrinite reflectance of source rocks in Qiongdongna basin,the relationship between diamantane index and vitrinite reflectance(R°)were established.Undoubtedly,it will show great significance for determining the maturity of the condensate and natural gas of Ying Qiong basin.
