【Abstract】 Formation factors and mechanism of the laumontite in upper Triassic Yanchang group of Jingan oilfield are analyzed. The features of diagenesis and its effect on reservoirs are introduced. It is pointed out that the dissolution of laumontite may greatly improve lower porosity and permeability of the reservoirs, which is the most favorable distribution area of oilbearing reservoirs.更多还原
