摘要
川西白马庙气田蓬莱镇组沉积相,主要为三角洲前缘和滨、浅湖相沉积。针对此沉积相特征,应用了一种全新的地震储层研究方法。SpecDecomp(分频解释)技术,对河道砂进行识别和研究,结合三维可视化技术(Geoprobe)在三维空间对河道砂进行横、纵向上的刻画,更清楚的了解河道的展布情况,同时利用基于层提取地震属性,对河道砂进行物性的判别。该套技术可以大大优化钻井方案,减少勘探开发风险,提高经济效益。
The sedimentary facies of Penglaizhen Formation in Baimamiao gasfield includes deltaic front facies, shore facies and lacustrine facies. A new seismic-reservoir technique, Spec Decomp, is applied to studying these characteristics. Channel sand is analyzed in 3D space and its distribution is clearly realized by this technology integrated with the 3D visual Geoprobe. Simultaneously, the physical properties of channel sand are identified according to acquisition of seismic attributes. The technique may optimize the drilling program, reduce the risk of exploration and development and raise the economic returns.
