2011年8月中旬,吐哈油田三塘湖盆地条湖凹陷2口区域探井接连获得新发现。条27井试油获日产1.06m3油流,条25井常规试油获少量油流,扩展了条湖南缘勘探成果,条湖南缘带呈现出多层系含油、多类型油气藏共生、两排构造带叠合连片成藏的趋势,展示出良好勘探前景。三塘湖盆地是吐哈油田的重点探区,是吐哈未来发展最有利、最现实的战略接替区域。早在2000年,条5井的突破打破了荒原的沉寂,勘探人员信心百倍地部署条7井,但复杂的地下情况导致没有获得更多发现。2006年,在马朗凹陷马17井获得重大突破后,勘探
In mid August 2011, exploration wells in two areas of the Thanghu Sag in the Santanghu Basin, Tuha Oilfield, were newly discovered. Oil well of Well No. 27 was tested with 1.06m3 oil flow. The conventional well test of Well No.25 gained a small amount of oil flow, which extended the exploration results of the southern edge of Hunan Province. The Hunan margin showed a multi-layer oil-bearing and symbiotic multi-type reservoirs. The tectonic trend of superimposed contiguous reservoirs shows a good exploration prospect. The Santanghu Basin is a key exploration area of Tuha Oilfield and is the most advantageous and realistic strategic replacement area for Tuha’s future development. As early as 2000, the breakthrough of Well No.5 broke the silence of the wilderness, and exploration personnel deployed Confidence 7 wells with great confidence. However, complicated underground conditions led to no further discoveries. In 2006, a major breakthrough was made in Ma-17 well in Malan sag after exploration
