非洲D区的储层预测
|
摘要
本文以非洲D区为例,提出在低勘探程度地区,运用多种地震属性技术进行储层预测的方法,以最大限度地提高预测结果的可信度。具体研究思路是:基于测井、录井资料确定目的层段,建立目标储层发育模式;应用多种地震属性分析技术,结合地质、测井等资料发现和落实圈闭,进行综合评价,指导钻探部署。本文用这套预测方法分析了D区储层的分布范围及有利岩相分布特征,并提交了两口井位,钻探结果不仅与储层预测结果吻合,而且获得了良好油气显示。
Taking African D area as an example, the paper presented the method using multiple seismic attributes to carry out reservoir prediction in the area of less exploration, raising confidence of predicted result maximally. The concrete ideas of study are: creating objective reservoir developing mode on the basis of objective intervals defined by logging data; and using multiple analytic techniques of seismic attributes and in combination with geologic and logging data to discover and define traps, carry out integrative evaluation and guide drilling deployment. The paper used this set of predicting method to analyze the distribution range of reservoir and the distribution feature of favorable lithology in D area, provided two well-sites. The drilled result not only fitted into predicted results of reservoir, but also acquired good oil/gas show.
