井震反演识别复合砂体内单一河道
Recognition of Single Channel in Composite Sand Body Based on Well-seismic and Inversion
摘要
Abstract
With the well pattern successively infills,the distributing tend of reservoir sandbody is gradually determined,the distributing characteristics of sandbody in vertical direction can be accurately recognized according to the logging data,but that in horizontal direction is difficulty to be identified. Aiming at the problems of the heavy tasks and the ambiguity on the recognition of a single channel on well-tie sections,the technique of well-seismic and inversion to predict the boundary of a single channel in composite sand body was proposed in the paper,and the river channel boundaries were further proved by the logging curve characteristics. Four typical indicators of the single river channel in composite sand body are recognized on the inversion sections,8 synchronous but not simultaneous single channels are identified clearly by sandstone poor belt conditions of the seismic inversion plan. With the single channel recognition achievement,good effects are obtained on the injection-production relation and remaining oil tapping,which shows a good application prospect.关键词
