摘要
受构造运动、气候变化、物源供应、古地貌和湖水动力条件等综合因素的控制，滩坝砂岩常为砂泥薄互层，其分布规律非常复杂，使利用常规地震属性预测技术和测井约束反演技术进行储层预测的难度增大。因此，利用近年发展起来的基于薄层反射调谐原理的频谱成像技术对X区块滩坝砂岩进行预测，结果表明该技术对滩坝砂岩储层预测具有可行性，解决了X区块长期面临储层平面变化大、砂层多、单层厚度小、横向变化快的预测难题，为该区块的快速上产、高效开发奠定了基础。
Beach bar sandstone generally presents thin sand-shale interbed with very complex distribution under the combined influence of tectonic movement, climate change, source supply, palaeogeomorphology and hydrodynamic conditions etc, which increases the difficulty to predict reservoir by conventional seismic attribution technique and logging constrained inversion technique. Therefore, the frequency spectrum imaging technology, emerging recently based on the thin-layer reflection tuning principle, is adopted to make beach bar sandstone prediction in X Block, which has proved its feasibility in beach bar sandstone reservoir prediction. This technology solved the long-term problems in X Block, including great reservoir change in plane, multiple sand layers, thin thickness of single layer, frequent lateral reservoir change etc, laying the foundation for rapid increase in production and high efficiency production in X Block.
