摘要
松辽盆地古537区块勘探目的层的沉积相为三角洲前缘亚相,储层砂体薄、相变快、规律性差,精确预测困难。地震约束地质建模技术能有效地预测储层分布和物性特征,方法原理是,以地质资料和地震解释层位数据为基础构建构造模型,在测井数据控制下,以地震岩性反演数据为约束,采用序贯高斯同位协同模拟方法建立储层岩性模型,进行储层描述。在古537区块,利用该方法进行了储层砂体展布和厚度预测,结果与井点的储层特征基本吻合。
The sedimentary facies of exploration target in Gu537 block of Songliao Basin is mainly of delta front sub-facies,and the reservoirs are characterized by thin sandbodies,rapidly variable facies and bad regularity,which lead to it difficult for accurate reservoir prediction. Seismic constraint geologic modeling technique can effectively predict the distribution and physical properties of reservoir,firstly, structure model is built on the basis of geologic data and seismic interpreted horizon data;secondly,under the control of well logs,constrained by seismic lithology inversion data,proceeding interpolation among well according to the trend of seismic lithology inversion; finally,the reservoir lithology model is built by sequential Gaussian collocated co-simulation method for reservoir description. The method was applied to predict the distribution and thickness of sandbodies in Gu537 block,and the results are almost coinciding with the reservoir characteristics at well locations.
