Crop and core analyses show that the pluvial-fan glutenite reservoirs develop 7 lithofacieses with obviously different oiliness and fluidity. The studies show that the cross bedding-fine conglomerate facies from sheetflood deposition and the sandstone facies with parallel bedding have the best oiliness and fluidity, the matrix particle-supported middle-coarse conglomerate facies and the coarse sandstone facies with block-shaped conglomerate lie in the middle, the matrix-supported and disordered-argillaceous conglomerate facies and the fine aleurolite facies with waving beding are the worst. Combined with production performance data, the middle-coarse conglomerate facies and the coarse sandstone facies with block-shaped conglomerate are the main target facieses of the later development adjustment.%野外露头观察和岩心观察,洪积扇砂砾岩储层发育7种岩石相,不同岩石相的含油性和流动性差异明显.研究表明:片流沉积的交错层理-细小砾岩和平行层理砂岩相的含油性和流动性最好,杂基颗粒支撑-中粗砾岩相和含砾块状粗砂岩相含油性和流动性次之,杂基支撑无序-泥质砾岩相和波状层理粉细砂岩相储层含油性和流动性最差；结合生产动态信息,中粗砾岩相和含砾块状粗砂岩相是后期开发调整的目标岩石相.
