油藏地质建模及实时跟踪研究
Study on Reservoir Geological Modeling and Real-time Tracking
【摘要】 为了提高采收率,降低开发风险,以滩海地区某油田为研究对象,结合地质、测井、地震等资料,对该油藏进行实时跟踪地质特征综合研究。应用地质建模、随钻测井、地质导向等技术,建立了精细的三维地质导向模型,并根据随钻测井数据和综合地质信息,实时验证构造和储集层信息,对导向模型不断校正,使模型与实钻结果一致,还以该模型为基础,优化水平井钻井的前进轨迹。结果表明,此种方法的应用降低了海上油田开发风险,能取得良好的开发效果。
【Abstract】 Taking an oilfield in Beach area as an example,this paper focused on the geological features with real-time tracking technique based on logging and seismic data.A detailed geosteering model was built initially by geological modeling,logging while drilling and geosteering technique.According to logging while drilling data and synthetical geological information,the structural and reservoir informations were verified in real time and geosteering model was amended continuously in order to correspond geosteering model with the real drilling results.Forward tracking of horizontal well drilling was optimized based on geosteering model.The results showed that this method reduced the risk of offshore oilfield development and achieved positive effects.
【Key words】 geological modeling; real-time tracking; geosteering; horizontal well;
