中文摘要：

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一细小砾岩和平行层理砂岩相的含油性和流动性最好，杂基颗粒支撑一中粗砾岩相和含砾块状粗砂岩相含油性和流动性次之，杂基支撑无序一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。

英文摘要：

Crop and core analyses show that the pluvial-fan glutenite reservoirs develop 7 lithofacieses with obvi- ously 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-sup- ported 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.
