Petrological Characteristics Research of Denglouku Formation Reservoir in Changling Fault Depression, Southern Part of Songliao Basin

Article Preview

Abstract:

We analyzed the petrology characteristics of Denglouku formation reservoir in Changling fault depression, by 47 ordinary thin sections, 42 thin casting sections, 30 scanning electron microscopy samples and 19 cathodoluminescent samples. The results show that: the main rock types are feldspar debris sandstone and debris feldspar sandstone. The reservoir consists of low compositional maturity, relatively poor psephicity, well graded, high rock debris content. It suggests that the sedimentary environment has strong energy, the moving distance is short, the study area is near the mother rock zone. From north to south, granularity gets coarse. The main cement types are carbonate and argillaceous.
