哈拉哈塘地区东河砂岩-角砾岩沉积相研究

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田,油气储量丰富,凹陷中心部位的哈6井在角砾岩段地层中测试获低产油流,显示出良好的勘探前景。加强该地区的基础研究工作,弄清该地区东河砂岩段-角砾岩段的岩性地层和层序地层分布规律、沉积相展布及演化规律、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 area in the northern Tarim Basin is a key area for the oil-gas exploration of Donghe Sandstone.It has successfully explorated two oil-gas fields including the wells Donghetang and HD4 with abundant oil resource.After the well HD6 in the center of the sag has been tested in Sedimentary facies,low oil stream has also been discovered,which demonstrates better prospects in the exploration.The basic research in this area should be emphasized,because it is of guiding importance to clarify the volcanic rock strata distribution and Sequence strata distribution of the Donghe Sandstone in this area,the distribution and evolution of sedimentary facies.,as well as the distribution of the sandstone and reservoir.
