| 摘 要： | 千米桥潜山凝析油气田发现于1998年10月,于1999年6月产油气。它是渤海湾地区具有代表性的低位潜山油气田,油气藏为新生古储式,潜山北、南两侧的古近系生油凹陷为其油气来源,油气主力产层为奥陶系马家沟组海相碳酸盐岩,含油气面积为57.1km2,探明油气当量达394.68×108m3。该油气田位于黄骅坳陷北大港构造带东北倾没端,是一个受裂缝和岩溶洞穴共同控制的复杂油气田,储层非均质性强,油气分布复杂,勘探开发难度大。本文回顾了油田的勘探和发现历程。在论述潜山油气田地质特点的基础上总结了取得油气勘探突破的实践和认识,分析了此类潜山勘探的成败原因。

| Abstract: | Qianmiqiao Condensate field is discovered in October 1998 and began to yield commercial oil and gas in June 1999. It is located at the northeastern pitching end of Beidagang anticline belt in Huanghua Depression and is representative of low-positioned buried hills in Bohaiwan Basin. The main reservoir or pay bed is Ordovician upper Majiagou carbonate rock and hydrocarbon derived from Tertiary hydrocarbon source rocks in Banqiao and Qikou depressions on the north and south of it. The field covers a hydrocarbon area of 57.1km2 and holds proved reserves in-place up to 39.468×109m3. Exploitation activities have confirmed that the field is characteristic of complex anisotropic reservoir that is controlled by a number of fractures and karstificated caves, which is hard to ascertain the distribution rules of hydrocarbon in reservoir. The exploration history and enlightenment of the field are reviewed. The success during exploration and frustration during development are also discussed. |
