Study on high yield well reservoir characteristics and main controlling factors in Daniudi gasfield

Daniudi gas field is located in Yishan slope of Ordos basin, it is a typical low permeability compact gas field. Based on the research of Daniudi gasfield high yield well reservoir types, the reservoirs are divided into four types. The various types of reservoir rock composition, physical properties and microscopic pore structure characteristics, and high gas zone distribution pattern and main controlling factors of natural gas enrichment have been analyzed, the article made it clear that the effective combination of sedimentary micro phase, rock composition and micro pore structure are the main controlling factors of Daniudi gas field high yield, which has a guiding significance for seeking natural gas enrichment area and well deployment.
