| 英文摘要 | The Gasikule oilfield, including a deep layer E-3(1) and a shallow layer N-2(1) pool, is the largest one in the Qaidam Basin and its crude oil output accounts for 80% of total oil output in the basin. In order to understand the genetic mechanism of crude oils from this oilfield, crude oils from both E-3(1) and N-2(1) pools in the Gasikule oilfield were collected and analyzed using gas chromatography and gas chromatography-mass spectrometry. The geochemical characteristics of biomarkers in the crude oils were synthetically studied. The biomarker compositions indicate that the crude oils were derived from strong anoxic and saline-hypersaline lacustrine environment with a dominance of algal organic matter. It was also observed that the ancient salinity of the sedimentary environments Of the Source rocks for the N-2(1) crude oils was slightly higher than that for the E-3(1) crude oils. The E-3(1) crude oils were derived mostly from bacteria whereas the N-2(1) crude oils originated mostly from plankton. The maturity parameters of biomarkers reflect that the crude oils were low mature. The maturity of the E-3(1) crude oils was slightly higher than that of the N-2(1) crude oils. These results, together with research of crude oil formation, show that the N-2 and E-3(1) crude oils were yielded from free biological lipids, extractable organic matters and kerogen in the Tertiary source rocks deposited under an anoxic and saline-hypersaline environment at the stage of low maturity. |
