531井区 T2 k2低孔低渗油藏由于开发年限较长，地质特征复杂等因素，目前油藏已开发区存在产量递减快、油藏注水困难，地层压力保持程度低、含水上升较快、注采井网不完善等问题。系统分析了531井区T2 k2低渗油藏油藏的注水见效特征，并从沉积微相、注采井网井距、注采连通性、射孔等方面对对影响本油藏的注水见效因素进行分析，总结出了531井区 T2 k2低渗油藏的注水见效影响因素，对本油藏高含水期开发调整提供指导。同时为同类低孔低渗油藏开发调整提供指导借鉴。%T2 k2 low perm eability reservoir in 531 w ell area, with the long developm ent years and complex geological characteristics and other factors, appears problem s like production declining quickly, reservoir w ater injection difficulty, the low degree of pressure m aintenance, w ater content increasing rapidly, imperfect injection patterns, etc. This paper system atically analyzes the characteristics of effective w ater injection of the 531 w ell area T2 k2 low perm eability reservoir, and analyzes the effective factors which affecting the reservoir 's w ater injection from multiple perspectives, such as sedim entary m icrofacies, injection patterns, injection- production connectivity, perforation and so on.The w ater injection effective factors are found out for the guidance to the developm ent and adjustm ent of 531 w ell area T2 k2 low perm eability reservoir in the period of high w ater content.
