欢8块开发后期剩余油挖潜技术研究

摘要

欢8块1980年底投入开发，经过30多年开发，欢8块目前面临着区块含水上升，老井产量递减幅度加大等问题，开发形势十分严峻。本文针对区块目前存在问题，采用井震结合，VSP技术多种方法重新认识区块构造，在局部构造微高点侧钻，挖潜剩余油，分析水淹范围挖潜井间剩余油。%Aiming at the problems existed in Huan 8 block,such as rising block water cut and high production declination in existent wells,this paper discusses the application of a variety of measures such as well data/seismic data combination technology, VSP technology to recognize block structures,apply lateral drilling in the micro-high points of local structure to tap the potential of inter-well remaining oil.
