利用断面沟扇体系及基底形态、地震反射结构、粘土矿物组合、岩屑类型、重矿物组合明确古流向和物源。

Source orientation was studied by using Basement and fractured surface form, Seismic Reflection structure, Clay mineral Assemblages, cuttings type and heavy mineral Combination.

西部物源中花岗岩岩屑含量较高，致使储层刚性颗粒含量高、抗压实能力强，这是西部扇体储层物性普遍优于北部扇体储层物性的原因之一。

As the western provenance has higher content granite, so do the higher content hard particle, and which makes the reservoir has stronger ability to resist the compaction.
