一体化地质建模在新近系礁灰岩储层定量表征中的应用

以LH油田三维地质建模为实例，针对礁灰岩储层内部结构复杂的情况，提出了一种综合应用地震、测井及地质资料进行礁灰岩储层研究和地质建模的方法。LH油田主要含油层段为中新统珠江组礁灰岩，储层为台地边缘生物礁相，储层内部结构复杂。以井震资料为基础，以生物礁沉积过程和成岩作用为指导，对礁体内部结构进行了分析，预测了主力油层内部的差物性层空间展布。在地质模式、井点信息和地震属性约束下，采用随机模拟的手段，建立了地质模型，实现了多学科综合的储层定量表征，对无井区储层特征进行了预测，为开发方案的设计提供了地质依据。

Application of Integrated Geological Modeling to the Characterization of Neocene Reef Reservoir

Taking LH Oilfield as an example, a method of integrated geological modeling, using seismic, log and geological data, was applied to the characterization of Neocene reef reservoir.The reservoir of LH Oilfield belongs to Neocene Zhujiang Formation, a typical Neocene fringing reef on the carbonate platform margin.In order to predict the complicated inner stratum frame, a workflow was put foreward.Based on incorporated analysis of 3-D seismic data, cores and logs, the depositional and diagenetic process was figured out, and thus the inner frame of reef was worked out.Under the constraint of geological frame, logs and seismic attribution, a geological reservoir model was built up with stochastic modeling method.The prediction of reservoir characteristics in reef flat area,based on the study and geological model, has been proved by a new well.
