Quantitative study on Triassic diagenetic facies in Wuxia area, Junggar Basin
Online published: 2011-12-20
Reservoir properties are closely related to the burial diagenesis. By studying diagenetic facies, we can effectively determine the favorable reservoir which is directly related to reservoir properties. On the basis of reservoir characteristics and diagenesis analysis, by recovering the original porosity, we quantitatively calculated the visible compaction rate, visible cementation rate and dissolution rate of Triassic reservoir in Wuxia area. According to the calculation results, we made classification criteria for reservoir compaction, cementation and dissolution rate, and described the diagenetic facies characteristics of nine types. By quantitative evaluating the diagenetic facies, it is considered that the favorable reservoirs mainly distribute in the area ofWuerhe nose uplift and Xiazijie fault zone with mediumcompaction, weak cementation and strong dissolution.
