复杂断块油藏注水见效影响因素研究与实践

Research and Practice on Influencing Factors of water injection effect in complex fault block reservoir

注水开发为复杂断块油藏驱油主要手段,油井注水见效差别却很大,以XX断块为例,应用动静态资料,从构造、储层等地质特征及注水开发井网多方面分析影响注水效果的因素,并将研究成果应用到注采井网的调整中,提高最终采收率。对复杂断块油藏高效注水开发具有极其重要的意义。

Water flooding is the main means of oil displacement in complex fault block reservoirs,but the effect of water injection on oil wells is quite different,taking XX fault block as an example,dynamic and static data are applied,The factors influencing water injection effect are analyzed from geological characteristics such as structure,reservoir and well pattern,The research results are applied to the adjustment of injection production well pattern to improve the final recovery.It is of great significance for high efficiency waterflooding development of complex fault block reservoirs.
