在油田开发中，注水时机、注入方式及注入量对油田的开发效果有着相当重要的影响， 确定合理的注水方式及注入规模对桑合油田高产稳产时间以及提高油藏采收率都十分必要。通过对桑合油田储层岩石特征、岩石敏感性试验分析，结合油田开发过程中取得的认识，认为提前注水、温和注水能够提高诸如桑合油田这类规模小、孔渗性好的复杂断块油藏的开发效果。

The time, mode and rate of water injection have quite important effect to the development result of oilfield. The
determination of reasonable injection mode and dimensions are seriously necessary to the production rate and recovery of Sanghe Oilfied. Based on the analysis of rock characteristics and rock sensitivity test combined with cognition obtained from the development process, it is believed that early and moderate injection can enhance development effect of complicated and faulted oilfields with small scale and high porosity & permeability, such as Sanghe Oilfield.
