塔河油田深层碎屑岩非构造圈闭地震勘探技术
|
摘要
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 continuous increase of exploratory efforts, the targets for exploration in Tahe oilfield are more and more complex, which are dominated by non-structural reservoirs with buried depth of more than 4 000 meters. Such reservoirs are characterized by low amplitude structure, small sand thickness and large lateral variation, being difficult to identify and evaluate. For these problems, a series of technologies for identification and evaluation of deep clastic non-structural trap in Tahe oilfield is developed, including forward modeling, fine coherent fault interpretation, seismic waveform analysis, seismic attribute acquisition and optimization, seismic-logging inversion, 3D visual geologic object detection, etc., which provide powerful supports for further exploration in Taha oilfield and incremental reserves and production of northwest oilfield company.
