【摘要】 红台气田三间房组是一个以凝析气藏为主的勘探开发重点区域,而依据目前的勘探开发现状,红台气田当前存在的主要问题有:砂体发育变化大,储层认识不清;储层具有低渗透、非均质性较强的特点,气层连片性差,同时又受断层封隔,储量丰度平面差异较大。因此,需要进行精细的油藏描述,建立适应气田开发调整的三维地质模型。综合地震、测井和地质的研究成果建立地层格架,结合相控建模,利用序贯指示随机模拟建模方法进行气藏的属性建模,所建地质模型反应了地下地质体三维空间分布特征,为拓展三间房组勘探开发和挖掘潜力,寻找有利储层发育带和天然气分布规律提供了有利依据。更多还原

【Abstract】 Sanjianfang formation in Hongtai gas field is a key exploration area which is rich in condensate gas.But there are some problems in Hongtai gas field under current status such as sand bodies change a lot;the reservoirs,which have low permeability and high heterogeneity,are not known clearly.The gas zones are not interconnected and seperated by the faults.The reserves abundance in plane varies greatly.Therefore,fine reservoir description is needed to establish a 3d geological model which is suitable for the gas field.Seismic,well logging and geological researches are combined to establish the stratigraphic framework.With facies-controlled modeling,the sequential indicating stochastic simulation modeling method is used to set up the gas reservoir attribute modelling which will response three-dimensional space distributional characteristics of the undrground geological bodies.It provides a favorable basis for exploration and development of Sanjianfang formation and looking for valuable reservoir growth zones and natural gas distribution law.更多还原
