| 摘 要： | 塔里木盆地阿克库勒地区三叠系岩石样品的物性表明,砂岩的物性受沉积相的控制，纵向上中油组物性最好,上油组最差,砂岩以中等喉道为主;砂岩的孔隙度受到胶结物、分选性和成岩作用的影响,压实作用和胶结作用使砂岩孔隙度减少25%左右,而溶蚀作用使研究区三叠系孔隙度增加12%左右;成岩作用已达到晚成岩作用的B期。

| Abstract: | The petrophysical property of Triassic reservoir in Arkekule are in Tarim basin is controlled by sedimentary facies, with the better of the middle oil layer and the poor of the upper oil layer as well as sandstone of medium throat radius. The porosity of sandstone reduces by about 25%, due to influences of cementation and compaction (sorting and diagenesis), whereas the porosity of Triassic reservoir increases by about 12% for dissolution. It is concluded that the diagenesis stage has been up to stage-B of late diagenesis. |
