摘要: 针对鄂尔多斯盆地上古生界二叠系盒8砂岩岩性气藏非均质性强、开发前期井少、井距大、储层预测难的特点,通过地震多种属性分析,并结合井资料,利用地质统计学方法优选出对砂岩厚度、储层物性及含气性较敏感的地震波形、地震波速度变异参数和地震子波吸收系数3种属性,根据这3种地震属性的分类特征对盒8砂岩厚度和储层含气性的平面分布进行了预测和描述,划分的Ⅰ+Ⅱ类含气有利区被确定为下一步的评价区块。地震属性分析应用于非均质岩性气藏的早期描述,为评价部署和开发方案编制提供了依据。

Abstract: The He-8 sandstone lithologic gas reservoir in Permian system of Ordos Basin can be described by stronger heterogeneity, small number of wells, larger well spaces and more difficult reservoir prediction during earlier stage development. Three optimal attributesseismic reflection waveform, variance parameter of seismic wave velocity and absorption coefficients of seismic wavelet have been sought out according to seismic attributes analysis results integrating well data by using of geologic statistics method. These attributes are sensitive to sandstone thickness, physical properties and gas bearing. The classifying characteristics of above three attributes have been used in the thickness prediction and description of gas reservoir distribution of He-8 sandstone. The resulting two types gas bearing zones (type Ⅰand Ⅱ) have been confirmed as the next appraisal areas. The application of seismic attributes analysis provided an important proof in evaluation deployment and making development plan for heterogeneous lithologic gas reservoir.

Key words: seismic attribute, lithologic gas reservoir, during production prophase, gas reservoir description
