Reservoir characteristics and influencing factors of Permian Wutonggou Formation in eastern slope of Jimusar Sag, Junggar Basin
Online published: 2011-06-20
Based on the basic theory and research methods of reservoir geology, the drilling, logging and testing data are used to analyze the reservoir characteristics and influencing factors of Permian Wutonggou Formation in eastern slope of Jimusar Sag, Junggar Basin. The porosity is relatively high, and the permeability is relatively low. The middle pore-thin throat is the main pore throat type, and the connectedness is relatively poor. The major influencing factors of reservoir physical properties are sedimentary facies and diagenesis. Compaction is the main factor for reducing pores, and cementation is the main cause for the low permeability. The favorable zones for high-quality reservoir development are braided channel of braid river delta plain and subaqueous distributary channel of front.
