储层建模技术是在油气藏描述基础上发展起来的,该技术近几年在各大油田的应用效果表明,其在水平井部署、剩余油挖潜等方面有着巨大的优势。针对磨溪气田雷一1气藏开发中存在的问题和研究的需要,综合利用气藏地震、测井及地质等资料,在对储层主控因素分析的基础上,根据确定性建模与随机建模相结合的原则、等时建模原则、相控建模原则,分别利用克里金法、序贯高斯模拟法和相控随机模拟法建立了雷一1气藏磨91井区储层模型。最后,利用容积法对模型可靠性进行了评价及方法优选。
Reservoir modeling technology was developed on the basis of reservoir description. The application effect of this technology in major oil fields in recent years shows that it has great advantages in horizontal well deployment and residual oil tapping potential. Aiming at the existing problems and research needs in the development of Lei-1 gas reservoir in Moxi gas field, based on the comprehensive analysis of the data of seismic, logging and geologic data of gas reservoirs, based on the analysis of the main controlling factors of reservoirs and according to the deterministic modeling and Stochastic modeling, the principle of isochronous modeling and the principle of phase control modeling, respectively, using Krychin method, sequential Gaussian simulation method and phase controlled stochastic simulation method, Layer model. Finally, the volumetric method is used to evaluate the model reliability and optimize the method.
