摘要: |
塔河油田位于塔里木盆地,为该盆地油气田中储量最大,产量最高的油田。下奥陶统是塔河油田最重要的储集层段,而下奥陶统中溶蚀成因的孔洞又是该层段最主要的储集空间。通过对该溶蚀段的研究,笔者认为该溶蚀段具有可以识别的测井响应,其密度呈指状急剧降低,是溶蚀段最明显的特征,并以此与中上奥陶统的瘤状灰岩形成明显区别。 |

Abstract: |
The Tahe oil field as a particularly prolific area is conspicuous in the Tarim Basin, Xinjiang.The Lower Ordovician strata are believed to be the significant reservoir intervals in the oil field, and the solution spaces in the Lower Ordovician strata may serve as the main reservoir spaces. The results in this study show that the solution intervals have the recognizable well logs, which tend to exhibit a sharp finger decline in density. In addition, there are also striking differences in density and bilateral electrical resistivity responses of the Lower Ordovician solution intervals and the Middle and Upper Ordovician nodular limestones. |
Key words: Tahe oil field solution interval nodular limestone |
