摘要
The tight sandstone gas prospecting is a key area of unconventional oil and gas exploration. The source rock of Shahezi Formation indicates adequate source condition for gas, which shows features of great thickness, wide distribution, high organic content and remaining high and overmature stages. Meantime, it possesses a reservoir condition with low porosity and low permeability, a conservation condition with good sealing, a well-matched migration condition, a favourable trap and good source reservoir caprock assemblage. It has qualifications for large-area tight gas reservoir.
