西部黄羊泉物源花岗岩屑含量高，致使储层刚性颗粒含量高，抗压实能力强。

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.

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.
