摘要: |
通过储层发育层段、储层类型、沉积演化、岩溶作用等方面的对比,发现塔北与塔中地区奥陶系碳酸盐岩储层在发育层位、沉积演化及岩溶期次上既有相似性,也有差异性。在塔中地区的油气勘探中,应注意下奥陶统古风化壳岩溶发育与塔北地区的差异性,加强对上奥陶统礁滩储集体的勘探。 |

Abstract: |
The comparative study of reservoir horizons,reservoir types,sedimentary evolution and karstification phases indicates that there are both similarities and differences in reservoir horizons,sedimentary evolution and karstification phases of the Ordovician carbonate reservoir rocks in northern and central Tarim Basin,Xinjiang.In the petroleum exploration in central Tarim Basin,particular attention should be drawn to the Upper Ordovician reef reservoirs due to their differences in the development of palaeo-weathering crust karsts in the Lower Ordovician strata in northern Tarim Basin. |
Key words: Tarim Basin Ordovician carbonate rock reservoir karstification |
