Pore structure and influencing factors of Lower Karamay Formation in Hongshanzui area of Junggar Basin
Online published: 2008-12-15
The cast thin section, scanning electronic microscope, cast image analysis and mercury injection analysis are applied to analyze the pore structure of the Lower Karamay Formation reservoir in Hongshanzui area. The main pore type of the Lower Karamay Formation reservoir is secondary dissolved pore. The throat type is lamellar or curved lamellar, mainly of moderate and fine throat. The Lower Karamay Formation is mainly composed of type Ⅲ-Ⅳ reservoirs. The main influencing factors of the pore structure are sedimentation and diagenesis, and the cementation and dissolution are dominant factors.
