| 摘 要： | 塔河油田位于塔里木盆地沙雅隆起阿克库勒凸起西部,目前井控含油气面积约1800km2。它发现于1990年,是我国发现的第一个陆上古生代海相大油田。2004年探明石油储量为5.3×108t,原油年产量为358×104t。油田的主要产层为奥陶系浅海台地—斜坡相碳酸盐岩,其盖层为下石炭统区域性泥岩和膏盐岩,油源为寒武系—下奥陶统碳酸盐岩烃源岩。岩溶储集体发育,油气藏圈闭类型多样。论述了油田的发现和勘探开发历程、油藏的地质特征、油气分布规律,以及寻找海相碳酸盐岩油气田的启示。

| Abstract: | Tahe Oilfield, discovered in 1990, is a large Paleozoic oilfield in Xayar Uplift, Tarim Basin with a petroliferous area of 1800km2 in present. It is also the first Paleozoic marine origin oilfield discovered in continental China. It has the proved oil reserves of 530×106t (2004) and the crude oil production of 3.58×106t per year. Dominant pay pools are Ordovician neritic platform and slope facies carbonate rocks overlying the regional cap of Lower Carboniferous mudstone and anhydrock. Oil and gas traps are various and karst reservoirs are developed. Hydrocarbon sourced from the Cambrian and Lower Ordovincian carbonate rock. The discovered and proved history of the large oilfield, the geological characteristics of the oil reservoirs and the revelation for search and exploration are revealed. |
