摘要
重1井区位于准噶尔盆地西北缘哈拉阿拉特山脚下,地表复杂,目的层侏罗系齐古组埋深200~400m,具有丰富的稠油资源,用竖直井开采效果差。为了给钻水平井创造条件,在该区做了一块面积为3.216km2的高分辨率三维地震勘探。经严格的野外施工、精细处理、仔细标定和砂层追踪,获得了含油砂层的地质模型,为水平井钻探提供了依据。
The Zhong - 1 wellblock is located in the peidmont of Halaalate Mountain, northwestern Zhunger Basin, with a complex surface condition. The objective formation Jurrasic Qigu Formation contains rich viscous crude in the buried depth of 200~ 400m. Production by vertical well is of low effect. In order to make conditions for drilling horizontal well,a 3-D high-resolution seismic survey has been conducted on the atea of 3. 216km2. Through the strict field acquisition, fine proccssing, careful calibration and sand tracking, the geological model for the oil-bearing sand bas been got, which provides a basis for the drilling of horizontal well.
