摘要
油气勘探评价中,地震属性作为主要的储层预测手段,发挥了重要的作用。但由于地震属性自身的局限性、多解性,使得属性优选、多属性合理组合等方面难度较大,降低了预测的准确性。就上述问题,本文从地震属性的地球物理含义及所赋予的地质意义出发,重点开展了基本地震属性优先选择、古地貌背景约束下地震属性选取等四种方法的研究及应用效果的分析,有效地增强了地震属性预测的针对性,提高了预测能力和精度,在实际应用中取得了较好的效果。
As a main method for reservoir forecast, seismic attributes play an important role in oil-gas exploration and evaluation. However, the limitations and ambiguity of seismic attributes make attribute optimization and multi-attribute combination more difficult, reducing the accuracy of forecast. To the above-mentioned problems, this paper mainly studied and analyzed the application of four methods such as the optimization of basic seismic attributes, attribute selection under the restraint of old structure, based on the geophysical and geological meaning of seismic attributes. The application of these methods significantly increases the pertinence of the seismic attributes in reservoir forecast and the forecast ability and accuracy, thus getting preferable application effect.
