摘要
Based on the reservoir geochemistry theory and taking the lower third member of Shahejie Formation in Xia 502 block, the second member of Dongying Formation in Shang 546 block and the second member of Guantao Formation in Dalujia block in Linyi Sag as examples, the reservoir and fluid connectivity were researched by using traditional oil chromatographic fingerprint and nitrogen compounds distribution technologies.The results show that the similar distribution characteristics of crude oil nitrogen compounds reveal a good connectivity between different reservoirs and fluid in the same well field,on the contrary,the connectivity is poor.The fine recognition and identification characteristics of the nitrogen compounds can be used for the repeated and comparative analysis on the reservoir connectivity for different scholars.
