基于特征曲线重构的波阻抗反演在复杂储层预测中的应用
|
摘要
在目前储层预测方法中,基于测井约束的波阻抗反演作为一项关键技术,应用效果较为良好。对于其反演效果的优劣,声波测井资料品质具有显著影响。当声波特征曲线对有效储层与围岩差异的敏感性较低时,常规测井约束反演的结果对储层刻画能力会有所不足,而测井特征曲线重构技术则可以有效改善储层预测效果,提高砂体边界刻画的精度。在研究区实际地质特征分析的基础上,依据现有地震、测井资料,并结合储层预测需要,从声波测井资料的特点出发,在相关性分析基础上,将自然伽马、自然电位、电阻率等不同特征曲线按不同权重与声波资料融合,构建出重构特征曲线。最终在重构声波曲线基础上,通过测井约束波阻抗反演来表征储层。实际应用结果表明砂、泥岩得到良好区分,储层描述明显改善,为后续生产开发提供了有效指导。
In the current reservoir prediction methods,the wave impedance inversion based on the logging constraint is a key technology,and the application effect is relatively good. For the pros and cons of inversion results by this method,the quality of acoustic logging data is of great significance. When the acoustic characteristic curve is less sensitive to the difference between the effective reservoir and the surrounding rock,the result of the conventional logging constrained inversion will be insufficient for the reservoir characterization,while the technique of logging characteristic curve reconstruction can effectively enhance the effect of the reservoir prediction,improving the accuracy of sand body boundary characterization. Based on the analysis of the actual geologic characteristics of the study area and the available seismic and well logging data and combined with the requirement of the reservoir prediction,from the features of the acoustic logging data,the reconstructed characteristic curve is constructed by merging different characteristic curves such as the natural gamma ray,spontaneous potential,resistivity curves into the acoustic data in accordance with different weights. Finally,logging constrained wave impedance inversion is carried out to characterize the reservoir on the basis of the reconstructed acoustic curve. The actual application shows that the sandstone and mudstone are well distinguished and the reservoir description is obviously enhanced,which provides an effective guide for subsequent production and development.
