一些地震相，如丘状相、披复相、前积相和杂乱相与油气聚集有直接的关系。
Some of the facies like mounds, drapings, foreset and chaotic facies are believed to be directly related to oil and gas accumulations.
该相沉积厚度相对较大，在地震剖面上反映为丘状隆起，内部反射杂乱，呈乱岗状反射，多沿主要构造线延伸。
The facies has large depositional thickness, showing colina shape, desultory interior reflections and extension along major structural alignment on seismic section.
