Abstract

Abstract

"Carbonate sandwich shale oil" is a main exploration target in the Subei Basin. The deep depression-inner slope zone of the Gaoyou Sag is a favorable area for the exploration of "carbonate sandwich shale oil" in the second member of Funing Formation (E₁f₂). The source rock and reservoir quality, engineering conditions and movability of each shale section of E₁f₂ were analyzed in order to further clarify "sweet spot" sections by using scanning electron microscopy, mercury intrusion at elevated temperature, nitrogen adsorption, CT scanning, X-ray diffraction, triaxial mechanics, multi-temperature pyrolysis and other research methods. The E₁f₂^shale1 and E₁f₂^shale2 in the deep depression-inner slope zone of Gaoyou Sag were deposited in a dry, hot, reducing and brackish water environment, developing favorable shale with high organic matter content. The TOC contents are 2.33% and 1.63%, respectively Kerogens are mainly of types Ⅰ and Ⅱ₁, with the most favorable conditions for hydrocarbon generation. The interlamellar pores were well developed, and the reservoir space is dominated by macropores and fractures. The brittle mineral content of E₁f₂^shale1 to E₁f₂^shale5 is 59.1%-63.6%, and the clay minerals are dominated by illite/montmorillonite mixed layer and illite. The brittleness index of E₁f₂^shale2 is 64.25% at most. In the range of burial depth greater than 3 500 m, the conversion of the illite/montmorillonite mixed layer to illite is obvious, and the shale brittleness and fracturing transformation conditions are better. The E₁f₂^shale1 and E₁f₂^shale2 in the deep depression-inner slope zone of Gaoyou Sag are exploration directions for shale oil in the Subei Basin.
