浅谈河南下二门油田物源方向的演绎规律

On the Variation of Sediment Supply for Xiaermen Oilfield,

在全面考察下二门地区古地貌特征的基础上，综合分析了关于下二门油田物源方向的各种即得学说，运用河流凸岸沉积，凹岸剥蚀的有关理论，创造性地提出了下二门油田的物源方向自深层系至浅层系。

There have existed different opinions upon the provenance of the Xiaermen oilfield, Henan. Previous interpretations suggest either a southeast, or a north, or a northwest source area, and this has severely restricted exploration and development performance in the oilfield. On the basis of a comprehensive study of the paleogeomorphologic and sedimentologic character of Xiaermen area, an analysis of the previous interpretations is made in this paper. And it is then pointed out that, from the deep sequence to the shallow sequence, the sediment supply has changed from coming from a southeast provenance to coming from a northwest provenance.
