摘要: 以黄骅坳陷明化镇曲流河储集层为例,在稀井网条件下,利用河道边缘检测等地震技术方法,结合沉积规律、生产测井资料,确定河道带展布特征,定量预测未期河道的边界与点坝位置,逐一描述单一河道分布,模拟并展现了整个地质事件连续的分布特征,同时也为井位的优化设计与方案的优化调整奠定了基础。Abstract: With Minghuazhen meandering river reservoir as an example, under the condition of sparse well pattern, with the seismic method of channel edge detecting and by study on sedimentation characteristic and well logging data, the distribution characteristic of channel belt is determined, the boundaries of latest channels and the location of point bars are predicted quantitatively, and the single channel is described one by one. In addition, the continuous distribution characters of the geological events are simulated. This provides a solid base for the optimization of well location design and making the development plan.
