| 摘 要： | 三叠系延长组长63段是鄂尔多斯盆地华庆地区重要的勘探目的层,也是典型的低孔-低渗储层.文章对长63砂岩的成岩相进行了初步研究,划分出碳酸盐胶结成岩相、绿泥石胶结成岩相、硅质充填及次生加大胶结成岩相、长石溶蚀成岩相.分析了成岩相与储层发育的关系及其区域分布规律,为进一步的岩性———地层油藏的成藏、规律分析和储层预测提供了依据.

| Abstract: | The Long Segment No. 63 of Yangchang Group of Triassic System is an important prospecting target zone as well as a typical low pore and low permeable reservoir in Huaqing Area in Ordos Basin. This paper carries on a preliminary study on the sandstone diagenesis of the Long Segment No. 63 and holds that it is divided into such diagenesis as carbonate binder, Fe - Mg chlorite binder, silicious filling binder with seconary expanding, feldspar corrosion binder. The relation between diagenesis and its changes and the orderleness of region distribution are further discussed so that the basis is provided for a further analysis on the oil reservoir of stone nature and stratum, orderleness and reservoir forecast. |
