Diagenesis and Features of Diagenetic Facies of Wumishan Formation of Jibei Depression——By Taking the Weizhangzi Section of Lingyuan County in Liaoning Province for Example

The key for a successful petroleum exploration in Jibei depression is to identify whether or not the efficient sealing and preserve conditions exist;while the favorable areas for exploring are those were not severely eroded during the Mid-upper Proterozoic,Paleozoic and Cenozoic.
