随着塔河油田勘探程度的不断提高,勘探对象也变得越来越复杂,寻找非构造油气藏是当前主要的任务,此类油气藏的特点是,埋藏深度大(4000m以下),圈闭幅度低,砂层厚度小,横向变化快,地震识别、落实与评价困难。针对上述特点,开发出了一套适于塔河油田深层碎屑岩非构造圈闭识别与评价的技术系列,主要包括正演模拟、精细相干断裂解释、波形分析、地震属性提取与优选、地震测井联合反演、三维可视化地质体检测等,从而扩大了塔河油田碎屑岩层系的油气勘探成果,并为此类油气藏的勘探开发提供了强有力的技术支撑。
With the continuous improvement of exploration in Tahe Oilfield, the exploration targets become more and more complex. Searching for non-structural reservoirs is the main task nowadays. Such reservoirs are characterized by large buried depth (below 4000m), traps Low amplitude, small sand thickness, rapid lateral change, earthquake identification, implementation and evaluation of difficulties. In view of the above characteristics, a series of technologies suitable for identifying and evaluating non-structural traps of deep clastic rocks in Tahe oilfield have been developed, including forward modeling, fine coherent fracture interpretation, waveform analysis, seismic attribute extraction and optimization, seismic Logging joint inversion and three-dimensional visualization of geological body, thus expanding the oil and gas exploration results of clastic rock strata in Tahe Oilfield and providing strong technical support for the exploration and development of such reservoirs.
