【摘要】：针对复杂多变的陆相曲流河沉积砂体,以储层构型研究理论为指导,综合运用岩心、密井网、测录井、开发动态等资料,深入剖析复合河道砂体空间配置关系。按单河道期次和隔夹层发育程度,从沉积速率与可容纳空间比值角度,对港西油田三区复合河道砂体叠置样式分析,结果表明,本区共有孤立型、桥接型、叠加型、切叠型和复合型5种砂体接触类型,其中孤立型和桥接型又按期次细分为2种样式。除孤立型砂体外,其余接触类型砂体均有不同程度的剩余油富集,受沉积韵律与隔夹层的影响,点坝内部隔夹层附近和切叠型砂体成为复合河道砂体内部剩余油的主控因素。
[Abstract]:In view of the complex continental meandering river sedimentary sand, to study the theory of reservoir structure guided by core, dense well pattern, well logging, reservoir dynamic data, in-depth analysis of the relationship between the allocation of composite channel sand body space. According to the single channel times and interlayer development degree, from the deposition rate and accommodation the ratio of angle of Gangxi oilfield three zone composite channel sand superimposition analysis results show that the total area of the isolated type, bridge type, superposition, cutting and stacking and composite 5 kinds of sand contact type, the isolated type and bridging and on the subdivided into 2 styles. In addition to isolated the sand in the remaining oil in different degrees the contact types of sand bodies were enriched, affected by the sedimentary rhythm and interlayer, point bar near the interlayer and cut stacking sand body dominated composite channel sand body internal factors of residual oil.
