摘要
本文主要通过分析下刚果盆地Hauter A区块下白垩碳酸盐储层的岩石地球物理响应特征,通过地震反射结构分析、正演模拟分析、分频处理、地震波形分类等手段研究储层发育有利相带、规模和范围,并通过叠前叠后反演、频谱吸收、地震多属性物性预测等手段建立了从相控反演(基本解决物性预测)→叠前反演(提高物性预测)→地震多属性+分频反演(物性定量预测)→LMR反演+吸收(烃类检测)等一套适合本区深层碳酸盐储层预测的技术流程。并针对本区碳酸盐储层埋藏较深、井少、储层薄、地震分辨率低等特点,在如何最大限度地挖掘地震资料的信息,提高反演可靠性方面取得以下成果:(1)本次将AVO属性处理和地震拓频技术进行结合,建立了适合本区储层地质特点的提高分辨率方法,为后续的精细反演提供了可靠的数据基础。(2)针对井少、储层横向变化快,为了减少反演的多解性,本研究将沉积相研究结果与三维地震建模和储层反演进行结合,利用沉积研究结果进行控制,建立了相控下的反演初始模型,减少了反演的多解性和模型化影响。(3)利用改进后的Fatti方程进行叠前联合反演,同时得到纵横波速度及密度三参数信息,这种方法在反演过程中考虑了Vp、Vs和密度之间的关系,使得反演结果更准确。大大提高了其岩性及物性预测的能力。(4)由于研究工区井少而且位于不同的构造带,加上深水钻探带来的经济风险,在储层研究的基础上,结合构造和有机地化等资料进行了成藏规律研究,并综合其研究成果对有利构造带进行综合评价,降低钻井风险。综合叠后、叠前反演、频谱吸收以及多属性分析等手段,利用概率法和信息融合法对有利储层分布规律进行综合评价。
In this paper, by analyzing rock geophysical response characteristics of Lower Cretaceous carbonate reservoir in he Lower Congo Basin Hauter A block, the scale and scope of favorable macro-facies is researched by means of structural analysis of seismic reflection, forward modeling analysis, Spectral Decomposition processing, seismic waveform classification, and a suite of technology workflow for deep carbonate reservoir prediction is established through Poststack and Prestack inversion, spectral absorption properties etc. for the region buried deep carbonate reservoirs, less wells , thin reservoirs and low seismic resolution on how to maximize the information of seismic data and improve the reliability of inversion has done the following innovations: (1) This will combine AVO attribute seismic processing and frequency extension technology, a suitable geological characteristics of the reservoir to improve the resolution method is established, it provides a reliable data basis for subsequent inversion of the data. (2) for less wells and quick lateral reservoir change, in order to reduce the inversion of multiple solutions, this research will combine sedimentary facies study and reservoir modeling and seismic inversion to integrate inversion through the use of sediment control studies. (3) through the use of improved Fatti equation, prestack inversion simultaneously obstain P-wave velocity, shear wave velocity and density of information, this method is considered in the inversion process of Vp, Vs and density relationship, it make the inversion results more accurate and Greatly enhance the ability to predict lithology and physical properties. (4) Because of less well and a different belt, it couple with the economic risks of deep drilling, this study based on the research in the reservoir, other structural and organic geochemical data develop a comprehensive evaluation for reducing drilling risk. On this basis, a comprehensive evaluation of reservoir distribution is done by using the probability method and the information fusion method.
