位于塔里木盆地塔东坳陷区跃进一号重力高北部沙雅县境的跃参一井,于1981年9月终孔,井深4747.18米。这是辽阔的塔东坳陷区目前唯一的一口深井。它对认识该区中新生代以来的地质构造、沉积发育及含油气远景等都有重要意义。该井钻遇上第三系(N)厚3564.5米(钻厚,下同),为黄灰,棕黄、浅褐、灰白等色细—粉砂岩、粉砂质泥岩和泥岩,含海相有孔虫和介形虫化石,与库车坳陷上第三系基本可比。
Located in the Tarim Basin, Tarim Basin, Yuejin County, one of the high-gravity north of Shaya County Yueshen a well, in September 1981 the final hole, well 4747.18 meters. This is the only deep well in the vast Tadong depression. It is of great significance to the understanding of the geological structure, sedimentary development and hydrocarbon-prospective since Cenozoic in the area. The well met the Tertiary (N) thick 3564.5 meters (drilling thickness, the same below), yellow, brown, light brown, gray and other color - siltstone, silty mudstone and mudstone, Foraminifer and ostracode fossils, comparable to the Tertiary in the Kuqa depression.
