摘要:

塔河油田位于塔里木盆地北部沙雅隆起阿克库勒凸起南部,是以奥陶系碳酸盐岩古岩溶油藏为主的油田,是我国第一个古生界海相大油田,储量规模超过十亿吨。笔者从其构造演化与沉积特征、油气藏特征与成藏模式等方面总结了所取得的成果与认识。实践表明,塔里木盆地古生界碳酸盐岩海相油气地质理论的不断丰富与完善是塔河油田发现和不断向外围、深部拓展的理论基础;成熟、配套、有效的勘探技术方法是实现重大发现的手段。

Abstract:

As the first marine Paleozoic giant oilfield in China and an oilfield dominated by palaeokarstic reservoir of Ordovician carbonate rock,Tahe is located on the southern Akekule Salient of Shaya Uplift,the northem Tarim Basin,with its reserves over 1 billion tons.The obtained results and knowledge about the oilfield are summarized by us in tectonic evolution,sedimentary patterns,reservoir features and hydrocarbon accumulation models.It has been practically demonstrated that continuous enrichment and improvement of petroleum geology theories on Paleozoie marine carbonate in Tarim Basin is a foundation for discovering Tahe oilfield and extending towards its periphery and deeper intervals,and that the mature,whole and effective exploration technology is a tool to make major discoveries.

Key words: palaeokarst, carbonate rock, result and knowledge of exploration, Tahe area
