磨溪气田雷一~1气藏储层建模研究及方法优选
|
摘要
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 has been developed on the basis of reservoir description and its application to big oilfields for recent years indicates a great advantage on deploying the horizontal well and searching for the remaining oil.Aiming at some existing problems and research requirements in T2l11 gas reservoir,we analyzed the main influencing factors on reservoir by means of seismic,well-logging and geologic data.Then,a reservoir model for Mo 91 wellblock was established by Kriging,sequential Gaussian simulation and facies-control stochastic model methods based on some principles,such as deterministic modeling with stochastic modeling,isochronal modeling and facies-control modeling.Ultimately,the model reliability was evaluated and the method was optimized by volumetric method and reservoir numerical simulation.
