Fluid inclusion characteristics and hydrocarbon charge history of Dibei gas reservoir in the Kuqa depression
摘要
Abstract
Hydrocarbon charge history of Jurassic reservoir of Dibei gas reservoir in the Kuqa depression was discussed by observation of fluid inclusion petrological characteristics, microthermometric analysis, infrared spectrum scanning, quantitative grain fluorescence analysis, and total scanning fluorescence. The results show that there are two episodes of hydrocarbon accumulation. Inclusions in the first phase are mainly gas-liquid inclusions with fluorescence colour of faint yellow and light yellow, which means that the maturity of the inclusion is relatively low. Hydrocarbon charging period in the first stage is from Jidike period to Kangcun period(23−12 Ma). Inclusions in the second phase are mainly gas-liquid inclusions with fluorescence colour of white blue, which means that the maturity of the inclusion is relatively high. Hydrocarbon charging period in the second stage is from Kuqa period totoday (5−0 Ma). Ingeneral, the hydrocarbon charge history is verified. Firstly, the reservoir is charged with oil from Jidike period to Kangcun period. Then the reservoir is charged with the superposition of natural gas in Kuqa period. Finally, the reservoir is adjusted, modified and re-enriched in Xiyu period.关键词
