塔北的哈拉哈塘地区是东河砂岩油气勘探的重点地区,该地区目前已发现并探明了东河塘和哈得4两个东河砂岩油气藏,油气储量丰富,显示出良好的勘探前景。基于哈拉哈塘地区东河砂岩段和角砾岩段的岩性段穿时沉积现象异常明显,根据层序地层学原理和方法对哈拉哈塘地区东河砂岩段-角砾岩段进行了重新分层和对比,在层序分层等时地层框架的基础上重新进行了东河砂岩段-角砾岩段沉积模式研究,弄清该地区地层分布规律、演化规律、砂体分布及储层分布规律对该地区的油气勘探具有重要指导意义。

The Halahatang region of western Tarim basin is the key areas of Donghe sandstone oil and gas exploration, there is an abundant oil and gas reserve and has a good exploration prospects, and two oil and gas reservoirs (the east Hetang and Hade 4) has been found here.Sedimentary diachroneity of Donghe sandstone and breccia is very obvious.Based on sequence stratigraphy, stratification and comparison was remade in Donghe sandstone and breccia, a sedimentary mode research on the basis of the construction of stratigraphic framework was made too, and finally the distribution and evolution rules of the strata, sandstone distribution rules as well as reservoir distribution rules was recognized, which was of important significance for the oil and gas exploration of this area.
