| 中文摘要:冀东潜山侏罗系主要分布于柏各庄凸起和西南庄凸起南部，其沉积体系主要为湿扇型冲积扇，也有湖泊滨岩沉积，其物源方向主要来自柏各庄凸起东部地区。侏罗系3个矿层组中I砂层组扇中辫状水道发育，但物性差；Ⅲ砂层组扇前缘辫状水道物性较好，但砂体厚度较薄；而Ⅱ砂层组扇中与扇前缘辫状水道都比较发育，且物性较好，为最有利的储集砂体。 |

| Abstract:The Jurassic buried hills in eastern Hebei Province are developed mainly in the Baigezhuang saliency and the southern Xinanzhuang saliency. The depositional systems of this area include wet alluvial fan and lake shore, with the sedimentary source derived from the eastern Baigezhuang saliency. The Jurassic has three sand sets and the braided channel is the most important subfacies. The braid channels of mid alluvial fan are developed very well in Sand Set Ⅰ, but the porosity and permeability of their sand bodies are not good. Sand Set Ⅲ develops braided channels of front alluvial fan, the porosity and permeability of their sand bodies are very good, but the sand bodies have very limited thickness. In Sand Set Ⅱ, braided channels of both mid alluvial fan and front alluvial fan are ideal; moreover, the porosity and permeability of the sand bodies are quite high. Therefore, the sand bodies in Sand Set II are most favo rable among the three sand sets. |
