扇三角洲沉积体明显地可划分为：扇三角洲平原亚相、扇三角洲前缘亚相和前扇三角洲亚相。
The fan deltaic body can be divided into three subfacies, named fan delta plain, fan delta front and pro-fan delta.
该构造储层属三角洲前缘亚相的水下分流河道微相沉积，并存在由成岩作用形成的次生孔隙发育带。
Its reservoir with secondary porosity zone is also a key for petroleum pool formation, which is of distributary channel of fan delta front.
砂砾岩储层的物性随着沉积环境的不同表现出较大的差异，且以扇三角洲前缘亚相水下分流河道微相最好。
Physical properties of the sandy conglomerate reservoirs differ greatly in different depositional environments, and the best occurs in underwater distributary channel on fan delta front.
