摘要：Recent years, progress has been made in hydrocarbon exploration of Shaximiao Formation in Sichuan Basin. The Shaximiao formation is fluvial facies deposit, the reservoir is channel sandstone with a low porosity and permeability, oil and gas generate from black shale of the Lianggaoshan formation and the Da’anzhai section of Ziliujing formation. In Longgang, immigration channel is the key condition of accumulation of Shaximiao formation. There are two kinds of immigration channels, fractures caused by hydrocarbon generation overpressure release and faults. Oil generated from Lianggaoshan shale immigrated to the sandstone of bottom part of Sha1, oil and gas generated from Da’anzhai black shale immigrated to upper part sandstone though faults. There is no water in the reservoir. Channel sandstone and source faults interpretation is the key point of exploration success.
