摘要
为了预测河道砂体的空间展布规律，进一步完善注采关系，挖潜剩余油，根据河道沉积特点和演化规律建立了孤立河道、削截河道、侧向迁移河道和不连续河道等4种河道砂体组合地质模型，基于测井曲线及随机模拟反演结果确定出4种河道砂体地质模型在地震反演剖面上的响应特征。反演剖面和反演属性图预测河道砂体在剖面、平面上的分布特征表明：通过地震反演可以在平面、剖面上识别这4种河道砂体组合类型，能够有效地预测河道砂体的空间展布形态。
In order to predict the space through-going laws of channel sandbodies, further improve the injection- and-production relation and tap the potential of the remained oil, four types of the geological models of channel sandbody sets, including isolated, truncated, laterally migrated, interrupted ones and so on are established according to the sedimentary features and evolution laws of the channels; based on the logs and the inversion results of random simulation, the response characteristics in seismic inversion profiles of the above four models are determined. The cross-sectional and planar distribution features predicted by the inversion profiles and inversion attribute maps show that with the help of the seismic inversion, the above four types of the combination, no matter horizontal and vertical, can be recognized and furthermore the space distribution states of the channel sandbodies can he effectively predicted also.
