【摘要】：储层三维地质建模即在三维空间上表征储层的各项地质特征,是油气藏勘探开发过程中揭示储层特征、寻找有利目标的基础。针对四川盆地龙岗气田鲕粒滩型碳酸盐岩储层非均质性强且研究区井网密度小等特点,形成了以单井解释数据为硬数据,地震属性体资料为约束,高度综合地质、钻井、测井、地震等资料的碳酸盐岩相控储层建模技术系列。该方法将纵向上小尺度精细井资料与地震资料高横向分辨率的优势有效结合,增加了井间预测的合理性,提高了地质模型的精度。建模结果再现了油藏三维空间展布特征,为油田详探、制订和调整开发方案提供了重要依据。
[Abstract]:Three-dimensional geological modeling of reservoir represents the geological characteristics of the reservoir in three-dimensional space, which reveals the reservoir characteristics in the process of exploration and development of oil and gas reservoirs. In view of the strong heterogeneity of oolitic beach carbonate reservoir in Longgang gas field in Sichuan Basin and the small density of well pattern in the study area, the hard data of single well interpretation and the constraint of seismic attribute body data are formed. A series of carbonate facies controlled reservoir modeling techniques for highly integrated geological, drilling, logging, seismic and other data. This method effectively combines the advantages of vertical small scale fine well data with high lateral resolution of seismic data. The rationality of cross-well prediction is increased and the precision of geological model is improved. The result of modeling reappears the three-dimensional spatial distribution characteristics of reservoir and provides an important basis for oil field exploration and formulation and adjustment of development plan.
