Abstract

Based on core observation, thin section identification, petrochemical analysis and reservoir property data analysis, the characteristics and significance of Carboniferous volcanic rocks in Dinan uplift were studied. The result shows that the Carboniferous volcanic rocks in Dinan uplift have the characteristics of coexistence of basic, intermediate and acidic, and intercrescence of subalkaline and alkaline series. Basic volcanic rocks mainly are alkaline series and distributed in Dixi 17 well area. Intermediate-acidic volcanic rocks can be divided into alkaline and sub-alkaline series, the former mainly distributed in Dixi 14 and 18 well areas, and the latter mainly distributed in Dixi 17, 14 and 10 well areas. The lithology distribution on the plane has obvious zonation showing the gradual transition from basic rock to acidic rock towards the southeast.Magmatic process controls the volcanic texture, structure and matrix properties, which led to a gradual deterioration of physical properties frombrecciated lava to volcanic tuff.
