研究表明：该凹陷沙三段层序低位域砂体发育下切水道充填，低位楔和低位扇。
The research shows that the lowstand sand bodies of the third member of the Shahejie Formation in the depression consist of incised channel deposits, lowstand wedges, and lowstand fan deposits.
后者储集体主要由由下切水道充填砂岩体、水下扇、废弃型三角洲等砂体组成。这些砂体均是良好的油气储层，并具有相似的成藏动力学过程。
The low stand fans in fault break mainly are almost all favorable reservoirs for oil and gas, and show similar dynamic progress of hydrocarbon accumulation.
