摘要
Changbei gas field is located in Yishan Slope of the northern center of the Ordos Basin, China. The main pay zone reservoir is Upper Paleozoic Lower Permian Shanxi P1S2 quartz arenite, which deposited in distributary channel of delta plain. The reservoir is low porosity low permeability tight reservoir with average porosity of 5.2% and average permeability of 0.7×10-3 μm2 in a current depth of 2 700～2 950 m. Integrated study on depositional environment, lithology, diagenesis and tectonic background has been conducted.
