Diagenesis of Triassic Zhongyou Formation and its influence on physical properties in AT1 area, Tahe Oilfield
Online published: 2011-02-20
Based on cast thin section, scanning electron microscope, electron microprobe and X- diffraction analysis, the diagenesis of Triassic Zhongyou Formation and its influence on physical properties in Tahe oilfield are studied. It is believed that Zhongyou Formation has lowcompositional maturity and textural maturity. The reservoir is mainly at late disgenesis stage A with complicated epidiagenesis. Compaction can reduce the porosity, while denudation is constructive to the increase of porosity.
