| 摘 要： | 石炭系底部的东河砂岩是一套优质储集层和富油层,也是塔里木盆地的主要产油层.本文从砂岩的成岩作用入手,通过对哈得4油田钙质胶结物作用的细致研究,识别出3期同生钙结成岩作用和4期表生钙结成岩作用,并总结了淡水方解石的矿物特征.结合东河砂岩的时空展布特征,确认了东河砂岩在沉积-成岩过程中遭受过抬升剥蚀,目前哈得4油田不足30 m的东河砂岩应为残余厚度.

| Abstract: | The Donghe sandstones in the base of the Carboniferous was an excellent reservoir and main oil-producting interval in the Tarim Basin. To start with a study on diagenesis, based on a detailed work on the calcic cementing materials in the Hade 4 oil field, distinguished 3 generations of syngenetic calcic-diagenesis and 4 generations of supergene calcic-diagenesis in the Donghe sandstones, and summed up the mineralogical characteristics of the fresh water calcites. To synthesize the spatiotemporal distributions of the Donghe sandstones, it could be confirmed that the Donghe sandstones experienced uplifting and erosion in its sedimento-diagenetic process, now the thichness less than 30 m in the Hade 4 oil field must be a relict one. |
