测井重构约束反演在大港油田CH二区储层建模中的应用
|
摘要
CH二区位于大港油田滩海地区,其特殊的地理环境导致资料获取困难,且井网稀疏。为了在此条件下建模,提出了基于地震资料为约束条件的地质建模思路。其主要依据三维地震资料和测井重构约束地震反演的预测结果,采用随机建模相的方法,对储层砂体井间分布和储层物性变化规律进行预测,建立高精度的储层三维地质模型。这种方法大大降低了井间储层预测的不确定性与开发风险,同时为类似工区开展储层精细评价提供较好的借鉴。
CH-2 area is located in beach area of Dagang Oilfield,where the special geological environmental results in difficulty in data acquisition and only a few wells scatter.To build model on this condition,this paper puts forward the geological modeling idea based on seismic data.It mainly depends on the three-dimensional seismic data and the predicting results of logging reconstruction and constrained inversion,using stochastic modeling,to predict distribution of reservoir sand bodies between wells and variation of reservoir properties,and to establish high-precision three-dimensional geological model of reservoir.This approach greatly reduces uncertainty of cross-well reservoir prediction and risk in development,and simultaneously provides good reference for precise reservoir evaluation in similar work area.
