黄河口凹陷馆陶组水源层评价
|
摘要
黄河口凹陷是渤海湾盆地重要的生烃凹陷,现阶段该凹陷中在生产油田基本都采用注水开发的模式,注入水源主要为新近系馆陶组(Ng)地层水。综合利用测井资料、地震响应资料以及区域沉积特征认识,通过随机模拟的方法分析了黄河口凹陷Ng地层和储层的展布特征;在此基础上结合研究区水源井实际生产资料,分析了水源潜力区域,对各油田Ng地层产水能力进行了预测。研究表明,黄河口凹陷Ng储层厚度大,连续性较好,是优质的水源层区域。
Huanghekou Sag was one of the important hydrocarbon genetic depressions in Bohai Bay Basin.At this stage,water flooding production pattern was used in most of the oilfields,and the injected water was mainly from Neogene Guantao Formation.In this study,based on the logging data,seismic data as well as the understanding of regional sedimentary features,the distribution characteristics reservoirs in Guantao Formation of Huanghekou Sag were analyzed by stochastic simulation method.Based on this analysis and the actual production data of water source wells,the formation water productivity of Guantao Formation was predicted,and the water source potential regions were studied.The results show that the reservoir in Guantao Formation has a great thickness with good continuity,and it is a high-quality water source area.
