The gas field having been found in Ordovician palaeocrust of Ordos Basin is large ancient landform gas accumulations and its gas containing area is closely related to distributive configuration of ancient valley trough on Ordovician erosion surface.
其含气面积与奥陶系侵蚀面古沟槽展布密切相关。

到目前塔河油田共有四口以奥陶系为目的层的水平井进行了成像测井,通过对这些成像测井资料的分析,可以看到水平井成像测井响应特征在某些方面与直井有较大的差异,如裂缝在直井中多为高视倾角而在水平井的FMI成像图上表现为视倾角较低,真倾角高;硅质团块、方解石充填裂缝等也与直井有较大的区别。

| 概 述 |
| 奥三面坝位于日本新泻县岩船郡朝日村、三面川水系(Miomotegawa)三面川上，地处磐梯朝日国立公园内。非对称式抛物线混凝土拱坝，最大坝高116m，水库总库容1.255亿m3。工程目的为防洪和发电，兼有减轻下游洪水危胁和维持河道正常功能作用。电站最大装机容量34.5万kW。1981年开工，预计2001年竣工。 |
