摘　　要：531井区T2k2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T2k2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T2k2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 permeability reservoir in 531 well area, with the long development years and complex geological characteristics and other factors, appears problems like production declining quickly, reservoir water injection difficulty, the low degree of pressure maintenance, water content increasing rapidly, imperfect injection patterns, etc. This paper systematically analyzes the characteristics of effective water injection of the 531 well area T 2 k2 low permeability reservoir, and analyzes the effective factors which affecting the reservoir ＇ s water injection from multiple perspectives, such as sedimentary microfacies,injection patterns, injection- production connectivity, perforation and so on. The water injection effective factors are found out for the guidance to the development and adjustment of 531 well area T2 k2 low permeability reservoir in the period of high water content.
